1,We Manufacturing processes are primarily classified into four types: 1:Forging, 2:Casting, 3:Cutting, 4:Rolling. 2,We can manufacture in accordance with these standards. Standards: GB Series (Chinese Standards), JB Series (Machinery Standards), HG Series (Chemical Industry Standards), ASME B16.5 (American Standards), BS4504 (British Standards), DIN (German Standards), and JIS (Japanese Standards). Internationally, there are two primary systems of pipe flange standards: the European system, represented by the German DIN standards (including those of the former Soviet Union), and the American system, represented by the US ANSI pipe flange standards. Other common standards include: the Chinese Ministry of Machinery Industry standards (JB series), the Ministry of Chemical Industry standards (HG series), the Chinese National Standard *GB/T 9112–9124-2010 Steel Pipe Flanges*, as well as US standards (ASME B16.5), British standards (BS4504), German standards (DIN), Japanese standards (JIS), and marine standards (CBM), among others. The nominal pressure ratings for the PN series are designated by "PN" and comprise the following nine levels: PN2.5, PN6, PN10, PN16, PN25, PN40, PN63, PN100, and PN160. The nominal pressure ratings for the Class series are designated by "Class" and comprise the following six levels: Class150, Class300, Class600, Class900, Class1500, and Class2500. Flange Classification 1. **According to Chemical Industry Standards:** Flanges are classified as follows: Plate Flat Welding Flange (PL), Necked Flat Welding Flange (SO), Necked Butt Welding Flange (WN), Integral Flange (IF), Socket Welding Flange (SW), Threaded Flange (Th), Butt Welding Ring Loose Flange (PJ/SE), Blind Flange (BL), Flat Welding Ring Loose Flange (PJ/PJ), and Lined Blind Flange (BL(s)). 2. **According to Petrochemical (SH) Industry Standards:** Flanges are classified as follows: Threaded Flange (PL), Butt Welding Flange (WN), Flat Welding Flange (SO), Socket Welding Flange (SW), Loose Flange (LJ), and Blind Flange (no specific designation). 3. **According to Machinery (JB) Industry Standards:** Flanges are classified as follows: Integral Flange, Butt Welding Flange, Plate Flat Welding Flange, Butt Welding Ring Plate Loose Flange, Flat Welding Ring Plate Loose Flange, Lap Joint Ring Plate Loose Flange, and Blind Flange. 4. **According to Connection Method/Type:** Flanges are classified as follows: Plate Flat Welding Flange, Necked Flat Welding Flange, Necked Butt Welding Flange, Socket Welding Flange, Threaded Flange, Blind Flange, Necked Butt Welding Ring Loose Flange, Flat Welding Ring Loose Flange, Ring-Type Joint (RTJ) Flange and Blind Flange, Large-Diameter Plate Flange, Large-Diameter High-Neck Flange, Figure-8 Blind Plate, Butt Welding Ring Loose Flange, etc. 5. **According to the Component Being Connected:** Flanges can be classified into Vessel Flanges and Pipe Flanges. 6. **According to Structural Type:** Flanges include Integral Flanges, Threaded Flanges, Flat Welding Flanges, Butt Welding Flanges, Lap Joint (Loose/Swivel) Flanges, and Blind Flanges. A flange—also referred to as a flange plate or rim—is a component used to connect shafts to one another, or, more commonly, to join the ends of pipes. Flanges are also utilized at the inlet and outlet ports of equipment to facilitate connections between two devices—for instance, the flange on a speed reducer. A "flange connection" or "flanged joint" refers to a detachable joint assembly comprising three interconnected elements—a flange, a gasket, and bolts—that together form a sealed structural unit. In the context of piping systems, a "pipe flange" specifically denotes a flange used for plumbing within the installation; when applied to equipment, it refers to the inlet or outlet flange of that specific device. Flanges feature a series of holes through which bolts are inserted to securely fasten the two flanges together, while a gasket placed between the flanges ensures a leak-proof seal. Flanges are broadly categorized into three types: threaded (screw-in) flanges, welded flanges, and clamp-type flanges. Flanges are invariably used in pairs; threaded flanges are suitable for low-pressure piping applications, whereas welded flanges are required for systems operating at pressures exceeding 4 kilograms per square centimeter. A sealing gasket is inserted between the two flange plates, which are then firmly secured using bolts. The thickness of a flange—as well as the specifications of the bolts used to fasten it—vary depending on the specific pressure rating required for the application. When connecting equipment such as water pumps or valves to piping systems, the corresponding connection points on these devices are often manufactured in the shape of a matching flange; this method of attachment is also referred to as a "flange connection." Generally, any connecting component that utilizes bolts to join and seal the perimeters of two flat surfaces—such as the joints in ventilation ducts—is termed a "flange"; such components may collectively be classified as "flange-type parts." However, since such a connection often constitutes merely a *portion* of a larger device—for instance, the interface between a flange and a water pump—it would be inappropriate to classify the entire water pump itself as a "flange-type part." Conversely, smaller components—such as valves—that feature such flanged interfaces may indeed be appropriately categorized as "flange-type parts." -:- For detailed product information, please contact sales. -: AISI M1015 Merchant Quality Carbon Steel Flange, Composition Spec Product Information -:- For detailed product information, please contact sales. -: AISI M1015 Merchant Quality Carbon Steel Flange, Composition Spec Synonyms -:- For detailed product information, please contact sales. -:

AISI M1015 Merchant Quality Carbon Steel, Composition Spec Product Information -:- For detailed product information, please contact sales. -: # Product Datasheet: AISI M1015 Merchant Quality Carbon Steel ## Composition Specification --- ### 1. PRODUCT OVERVIEW **AISI M1015 Merchant Quality (MQ) Carbon Steel** is a standardized low-carbon steel formulation specifically designated for general-purpose manufacturing and construction applications where **chemical composition consistency** is the primary procurement requirement, rather than guaranteed mechanical properties. The "M" prefix explicitly denotes **Merchant Quality**, establishing a clear commercial agreement that the material is supplied to meet precise chemical composition limits while mechanical properties are reported as typical values but **not guaranteed** by the producer. This quality designation represents the most economical tier of standardized steel procurement, optimized for applications where cost-effectiveness, predictable fabricability (weldability, formability, machinability), and consistent chemical response are prioritized over certified mechanical performance. M1015 MQ steel serves as a reliable, cost-controlled base material for non-critical components where design incorporates substantial safety factors or where the application does not require specific minimum strength values. --- ### 2. KEY SPECIFICATIONS & INTERNATIONAL STANDARDS | **Parameter** | **Specification** | |---------------|-------------------| | **AISI/SAE Designation** | **M1015** (Critical "M" prefix indicates Merchant Quality) | | **UNS Designation** | G10150 (Note: Shares UNS with standard AISI 1015; quality distinction is commercial) | | **Primary Governing Standard** | **ASTM A283/A283M** - Standard Specification for Low and Intermediate Tensile Strength Carbon Steel Plates | | **Relevant Supporting Standards** | **ASTM A575/A575M** - Steel Bars, Carbon, Merchant Quality, M-Grades
**ASTM A576/A576M** - Steel Bars, Carbon, Hot-Wrought, Special Quality (for comparison)
**ASTM A36/A36M** - Structural Steel (different philosophy: guaranteed mechanical properties) | | **Quality Philosophy** | **Composition-Constrained, Properties-Typical** | | **Common Product Forms** | Hot-rolled bars, merchant bars (angles, channels, flats), plates, occasionally sheets | **International Context & Quality Philosophy:** - **Europe:** No direct equivalent; similar to "non-alloy steel" with standard composition but without EN 10204 Type 3.1/3.2 certification - **General International:** Represents a specific North American commercial practice; other regions may use "Commercial Quality" or similar with different implications - **Key Distinction:** Unlike most international standards that either guarantee properties or are completely generic, MQ establishes explicit chemical limits without property guarantees --- ### 3. CHEMICAL COMPOSITION (% BY WEIGHT) - SPECIFICATION REQUIREMENTS | **Element** | **Composition Range** | **AISI 1015 Standard Range** | **Significance of Control in MQ** | |-------------|----------------------|------------------------------|-----------------------------------| | **Carbon (C)** | **0.13 - 0.18%** | Same as standard 1015 | Primary controlled element; ensures consistent weldability and formability response | | **Manganese (Mn)** | **0.30 - 0.60%** | Same as standard 1015 | Controlled for predictable hardenability and hot workability | | **Phosphorus (P)** | **≤ 0.040% max** | Same as standard 1015 | Residual control for consistent cold formability and weld integrity | | **Sulfur (S)** | **≤ 0.050% max** | Same as standard 1015 | Residual control balancing machinability and hot workability | | **Silicon (Si)** | **0.10 - 0.20% (typical)** | Same as standard 1015 | Deoxidizer control for consistent internal quality | | **Copper (Cu)** | **≥ 0.20% min (when specified)** | Optional in standard 1015 | **Key MQ option:** When specified for enhanced atmospheric corrosion resistance | | **Residual Elements** | Typically not specified | Varies | MQ may have less stringent control than SQ (Special Quality) grades | **Critical Manufacturing & Procurement Notes:** 1. **"When Specified" Elements:** - Copper content ≥ 0.20% is **optional** but becomes mandatory when specified on purchase order - This allows procurement of either standard or copper-bearing steel from the same M1015 designation 2. **Comparison with Special Quality (SQ):** - MQ typically has **less restrictive controls** on residual elements (Cr, Ni, Mo, Cu) - SQ grades (ASTM A576) may specify maximum limits for these elements to ensure weldability - MQ prioritizes chemical consistency of major elements over comprehensive residual control 3. **Certification Basis:** - Mill certifies **chemical composition only** - Mechanical properties may be reported but are **informational only** - No guarantee of meeting any specific mechanical property values --- ### 4.
