AISI M1010 Merchant Quality Carbon Steel, Composition Spec Product Information -:- For detailed product information, please contact sales. -: # Product Datasheet: AISI M1010 Merchant Quality Carbon Steel - Composition Specification ## 1. Product Overview AISI M1010 Merchant Quality (MQ) Carbon Steel is a versatile low-carbon steel formulation specifically designed for general-purpose applications where precise mechanical property guarantees are not the primary requirement. Designated with the "M" prefix to indicate "Merchant Quality," this grade prioritizes consistent chemical composition over guaranteed mechanical properties, making it a cost-effective solution for a wide range of fabrication and manufacturing needs. It represents a balanced approach between basic steel performance and economic feasibility. ## 2. Key Specifications & International Standards * **AISI/SAE Designation:** M1010 (Merchant Quality) * **UNS Designation:** G10100 (Note: Shares UNS with standard AISI 1010) * **ASTM Standards:** * **ASTM A283/A283M** - Standard Specification for Low and Intermediate Tensile Strength Carbon Steel Plates * **ASTM A570/A570M** - Standard Specification for Steel, Sheet and Strip, Carbon, Hot-Rolled, Structural Quality * **ASTM A36/A36M** - May be supplied to similar applications (though A36 has different composition) * **Quality Distinction:** The "Merchant Quality" designation specifically indicates that the material is sold primarily to chemical composition requirements rather than mechanical property guarantees. * **Common Product Forms:** Hot-rolled bars, structural shapes, plates, and occasionally sheets. ## 3. Chemical Composition (%, Specification Requirements) The chemical composition is the defining characteristic of M1010 Merchant Quality steel: | Element | Composition Range | Key Characteristics | |---------|------------------|---------------------| | **Carbon (C)** | 0.08% - 0.13% | Provides basic strength while maintaining good formability and weldability | | **Manganese (Mn)** | 0.30% - 0.60% | Controls sulfide morphology and provides modest strengthening | | **Phosphorus (P)** | ≤ 0.040% max | Residual element controlled for weldability | | **Sulfur (S)** | ≤ 0.050% max | Residual element affecting machinability and hot workability | | **Silicon (Si)** | Typically 0.10% max (when specified) | Deoxidizer, typically lower than structural grades | | **Copper (Cu)** | ≤ 0.20% (when required for atmospheric corrosion resistance) | Optional addition | *Note:* Merchant Quality steels typically have less restrictive residual element controls compared to "Special Quality" or "Structural Quality" grades. ## 4. Typical Physical & Mechanical Properties (Indicative Only) *Important:* For Merchant Quality steels, mechanical properties are **not guaranteed** by specification but typically fall within these ranges based on manufacturing practice: | Property | Typical Range | Condition | |----------|---------------|-----------| | **Tensile Strength** | 330 - 430 MPa (48 - 62 ksi) | Hot-rolled | | **Yield Strength (0.2% Offset)** | 230 - 280 MPa (33 - 41 ksi) | Hot-rolled | | **Elongation in 50 mm (2 in)** | 25% - 32% | Hot-rolled | | **Reduction of Area** | 45% - 55% | Hot-rolled | | **Hardness (Brinell)** | 105 - 125 HB | Hot-rolled | | **Modulus of Elasticity** | 190 - 210 GPa (27,500 - 30,500 ksi) | - | | **Density** | 7.85 - 7.87 g/cm³ (0.283 - 0.284 lb/in³) | - | | **Machinability** | 50-55% (compared to 1212 free-machining steel as 100%) | - | | **Weldability** | Excellent - All common methods without preheat | - | ## 5. Product Characteristics & Quality Philosophy **Merchant Quality Distinction:** - **Composition-Driven:** Primary conformance is to chemical composition limits - **Property Variability:** Mechanical properties may vary between heats and producers - **Cost-Effective:** Lower cost than steels with guaranteed mechanical properties - **Fabricator's Responsibility:** End-users must qualify material for specific applications - **Typical Applications:** Suitable where exact strength values are not critical to design **Key Material Properties:** - **Good Formability:** Can be bent, formed, and fabricated with standard equipment - **Excellent Weldability:** No special procedures required for most welding methods - **Adequate Machinability:** Acceptable for general machining operations - **Limited Hardenability:** Cannot be effectively through-hardened; case hardening possible - **Surface Quality:** Standard hot-rolled surface with mill scale ## 6. Typical Applications M1010 Merchant Quality steel is specified where consistency in fabrication response is more important than exact strength values: **Construction & Infrastructure:** - Non-critical structural components - Construction brackets and supports - Temporary structures and formwork - Building hardware and accessories **Manufacturing & Fabrication:** - General fabrication projects - Machine bases and frames (non-precision) - Guard rails and safety barriers - Storage racks and shelving (light duty) **Agricultural & Industrial:** - Equipment frames and housings - Trailer components - Agricultural implement parts - Conveyor system components **Consumer Products:** - Furniture frames - Exercise equipment components - Hand tool components (non-cutting) - Recreational equipment parts ## 7. Comparison with Other 1010 Variants | Grade Type | Primary Focus | Property Guarantees | Typical Cost | Application Focus | |------------|---------------|---------------------|--------------|-------------------| | **M1010 (Merchant Quality)** | Chemical Composition | None | Lowest | General fabrication, non-critical uses | | **1010 Commercial Quality** | Dimensional & Surface | Limited or typical values | Low | Light forming, good appearance | | **1010 Structural Quality** | Mechanical Properties | Minimum yield/tensile | Medium | Load-bearing applications | | **1010 Drawing Quality** | Formability | Forming parameters | Higher | Severe forming, deep drawing | ## 8. Processing Considerations **Fabrication Notes:** - **Welding:** No restrictions; all standard processes applicable - **Forming:** Good for moderate bending and forming operations - **Machining:** Use standard low-carbon steel machining parameters - **Heat Treatment:** Not recommended for through-hardening; responds well to case hardening (carburizing) - **Surface Preparation:** Mill scale should be removed for painting or plating (shot blasting, pickling, or grinding) **Quality Assurance:** - Purchase orders should specify "Merchant Quality" or "M1010" designation - Certifications typically provide chemical analysis only - For critical applications, consider upgrading to Structural or Special Quality grades - In-house testing of mechanical properties may be warranted for new suppliers ## 9. Remarks & Selection Guidance AISI M1010 Merchant Quality steel represents the most economical tier of specified carbon steel, ideal for applications where: - Design loads are well below material capability - Fabrication consistency is more critical than exact strength values - Cost optimization is a primary consideration - The component is not safety-critical **When NOT to use M1010 Merchant Quality:** - Safety-critical structural applications - Applications requiring certified mechanical properties - Components subject to dynamic or fatigue loading without substantial safety factors - Applications where consistent batch-to-batch mechanical performance is essential **Procurement Advice:** Always communicate with suppliers about the intended application and ensure "Merchant Quality" is clearly specified. For applications approaching the typical strength values, consider specifying Structural Quality (SQ) or requiring mill test reports with actual mechanical properties. --- *Note: This datasheet provides general information about AISI M1010 Merchant Quality Carbon Steel.
