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.

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. -: Sandvik 19C27 Strip Steel Flange Product Information -:- For detailed product information, please contact sales. -: Sandvik 19C27 Strip Steel Flange Synonyms -:- For detailed product information, please contact sales. -:

Sandvik 19C27 Strip Steel Product Information -:- For detailed product information, please contact sales. -: ## **Sandvik 19C27 Strip Steel – High-Carbon Martensitic Stainless Steel for Wear-Resistant Components** ### **Product Overview** Sandvik 19C27 is a specialized **high-carbon, high-chromium martensitic stainless steel strip** engineered for applications requiring exceptional wear resistance, moderate corrosion protection, and high hardness in through-hardened condition. Positioned between standard cutlery grades and specialized tool steels, 19C27 offers an optimal balance of hardness, carbide formation, and stainless properties for demanding industrial components subjected to abrasive wear and mechanical stress. ### **Key Advantages** * **Superior Wear Resistance:** High carbon content combined with chromium carbides provides excellent resistance to abrasive and adhesive wear. * **High Hardness Potential:** Can achieve hardness levels up to 60-62 HRC through proper heat treatment, suitable for demanding tooling applications. * **Good Corrosion Resistance:** Offers better corrosion resistance than tool steels like D2 or A2 due to higher chromium content, suitable for humid or mildly corrosive environments. * **Good Dimensional Stability:** Exhibits relatively low distortion during quenching compared to some high-alloy tool steels. * **Optimized Carbide Structure:** Controlled manufacturing produces a uniform distribution of carbides for consistent performance. ### **Chemical Composition (Typical, wt%)** The composition is balanced to form hard chromium carbides while maintaining adequate corrosion resistance. | Element | Content (%) | Element | Content (%) | | :--- | :--- | :--- | :--- | | **Carbon (C)** | 0.90 - 1.00 | **Chromium (Cr)** | 13.0 - 15.0 | | **Silicon (Si)** | 0.30 - 0.60 | **Manganese (Mn)** | 0.30 - 0.60 | | **Molybdenum (Mo)** | 0.40 - 0.70 | **Vanadium (V)** | 0.10 - 0.20 | | **Sulfur (S)** | ≤ 0.015 | **Phosphorus (P)** | ≤ 0.025 | | **Iron (Fe)** | Balance | | | *Note: The elevated carbon (>0.9%) enables high hardness, while molybdenum and vanadium additions refine grain size and improve toughness.* ### **Physical & Mechanical Properties** #### **Properties in Annealed Condition (as supplied strip):** * **Density:** 7.7 g/cm³ * **Modulus of Elasticity (E):** 200 GPa * **Hardness:** 200-230 HB * **Tensile Strength:** 700-850 MPa * **Yield Strength:** 550-700 MPa * **Elongation:** 10-15% * **Microstructure:** Spheroidized carbide structure in ferritic matrix #### **Properties after Hardening & Tempering:** * **Recommended Austenitizing:** 1010-1040°C * **Quenching:** Oil or forced air * **Tempering Range:** 180-250°C for maximum hardness * **Achievable Hardness:** **58-62 HRC** * **Tensile Strength:** 2100-2400 MPa * **Compressive Strength:** ~3000 MPa * **Toughness:** Moderate for achieved hardness level #### **Corrosion Resistance:** * Resists atmospheric corrosion, water, steam, and mild chemicals * Superior to conventional tool steels in humid environments * Not suitable for severe chemical or marine applications ### **International Standards & Approvals** * **Sandvik Proprietary Grade:** **19C27** * **Similar/Equivalent Standards:** * **EN / DIN:** 1.4108 / 1.4034 (X90CrMoV18) * **AISI:** 440C modified * **UNS:** S44004 * **ISO 4957:** Tool steels - Stainless * **Industry Specifications:** Recognized in tooling and component manufacturing sectors ### **Product Applications** #### **Cutting & Slitting Applications:** * Industrial cutting blades for paper, textiles, and plastics * Slitter knives for metal and non-metal materials * Guillotine blades for soft materials * Food processing blades #### **Tooling & Wear Components:** * Plastic injection mold components (cores, cavities, ejector pins) * Die components for forming and stamping * Wear plates and guides * Measuring instruments and gauges * Valve seats and seals #### **Industrial Components:** * Pump shafts and sleeves * Bearing races and components * Fastener manufacturing tools * Textile machinery components #### **Specialty Applications:** * Surgical and dental instrument components * High-wear fasteners * Precision mechanical components requiring wear resistance ### **Processing Guidelines** #### **Forming & Machining:** * **Annealed State:** Good machinability (approximately 60% of free-cutting steel) * **Forming:** Limited formability in annealed state;
