STKMRS370 Non-Alloy Steel is a type of non-alloy steel pipe primarily used in mechanical and industrial applications where high strength and accuracy are required. STKMRS370 steel is commonly used in construction components, machinery, and other applications.

Key Characteristics of STKMRS370 Non-Alloy Steel:

- Chemical Composition:
- Carbon (C): Approximately 0.30-0.40%, providing hardness and strength to the steel.
- Manganese (Mn): Approximately 0.60-0.90%, enhances ductility and impact resistance.
- Silicon (Si): Approximately 0.15-0.35%, helps in hardening the steel and improving corrosion resistance.

- Physical Properties:
- Tensile Strength: Approximately 370 MPa, allowing the steel to withstand tensile forces well in strength-demanding applications.
- Hardness: Can achieve higher hardness after heat treatment processes like quenching and tempering.
- Machinability: Good, easily machinable using conventional methods such as turning, milling, and grinding.

- Applications:
- Construction Industry: Used in the production of steel pipes for construction applications, such as structural frameworks and load-bearing components.
- Machinery Industry: Applied in machinery and equipment requiring high precision and strength.
- Automotive Industry: Used in the production of automotive components such as shafts and other high-strength parts.
- Manufacturing Industry: Utilized in producing steel products with high strength and quality requirements.

- Shape and Size:
- STKMRS370 steel is commonly supplied in the form of steel pipes, with dimensions and thicknesses depending on the specific requirements of each application.

Manufacturing and Processing:
- STKMRS370 steel is typically produced through basic steelmaking processes and hot or cold rolling to form the final product. Afterward, the steel may be heat-treated to enhance its mechanical properties.
