What is ST37 Hot Rolled Steel Coil?
ST37 hot rolled steel coil (also known as black iron coil) is a low-carbon, general-purpose structural steel widely used across various industries. “ST37” refers to the German standard DIN 17100 grade, with a minimum tensile strength of 370 MPa.
As a hot rolled black iron product, it features:
-
Dark blue-black surface from the hot rolling process (mill scale)
-
Excellent formability for bending, rolling, and stamping
-
Good weldability for easy fabrication
-
Cost-effective compared to cold rolled alternatives
ST37 is equivalent to S235JR (EN) , A283C (ASTM) , and Q235B (GB) standards.
This makes it the ideal choice for general construction, automotive parts, pipe manufacturing, and various fabrication projects where surface finish is not the primary concern.
