S70MC is a type of steel plate that is commonly used in construction, engineering, and industrial applications. Here are some key properties and characteristics of S70MC steel: - Grade: S70MC - Material: High-Strength Low-Alloy (HSLA) Steel - Thickness: 4mm-150mm - Width: 1000mm-3000mm - Length: 3000mm-12000mm - Yield Strength: 700 MPa (min) - Tensile Strength: 850-1000 MPa - Elongation: 15% (min) - Impact Test: -20°C (optional) - Heat Treatment: As rolled or normalized - Applications: - Construction equipment - Industrial machinery - Automotive parts - General engineering - High-strength applications - Features: - High strength and toughness - Good weldability and machinability - Good corrosion resistance - Affordable price S70MC steel is known for its excellent strength, toughness, and weldability, making it a popular choice for various industrial applications. Note: S70MC is a designation from the European standard EN 10149-2, where: - S = structural steel - 70 = minimum yield strength (700 MPa) - MC = high-strength low-alloy steel The exact composition and properties of S70MC steel may vary depending on the specific standard or specification being followed.
