What material is STKM13A?

STKM11A is JIS G3445 carbon steel pipe for machinery. This material is tougher than mild steel, offering higher tensile and yield strengths while maintaining good bending properties.

Material

STKM11A typically has a carbon content of around 0.10-0.20%. In addition to carbon, it also contains appropriate amounts of manganese, phosphorus, and sulfur. These additions maintain toughness and weldability, making it particularly reliable for bending, forging, and post-processing.

Characteristics

Due to its low carbon content, it offers excellent weldability. It also has good ductility, making it suitable for machining. It also has moderate strength, meeting basic structural requirements.

Can STKM13A Tube be used in automotive applications?

Yes. STKM13A is typically used in automotive seat frames, steering columns, and suspension components. Its excellent weldability and stable dimensional accuracy make it an ideal choice for components requiring both safety and manufacturability.

STKM13A offers an excellent balance of weldability, toughness, and cost-effectiveness, making it an ideal choice for machine frames, furniture, and automotive components. However, customers should carefully select the material based on their application needs: STKM13A is ideal for structural and medium-load applications, while other materials should be considered for high-pressure or extreme environments.
