ST37 is a commonly used designation for carbon steel. It refers to a low-carbon steel grade that conforms to the German DIN 17100 standard. ST37 carbon steel is also known as mild steel or plain carbon steel and has a relatively low tensile strength compared to other steel grades.
The chemical composition of ST37 carbon steel typically includes:
- Carbon (C): 0.17% – 0.20%
- Manganese (Mn): 1.40% – 1.60%
- Phosphorus (P): 0.045% max
- Sulfur (S): 0.045% max
- Silicon (Si): 0.17% – 0.35%
ST37 carbon steel plates are used in various applications, including general structural purposes, manufacturing of automotive parts, construction machinery, and more. It is relatively inexpensive and offers good weldability and machinability.
