DIN standard HI Boiler and Pressure Vessel Steel Plate

DIN standard HI is a specification for boiler and pressure vessel steel plate, which is used for high-temperature service applications. The steel plate is typically composed of carbon and manganese, which provide good strength and ductility, and are suitable for welding.

The mechanical properties of DIN standard HI steel plate are as follows:
Tensile strength: 400-510 MPa
Yield strength: 235 MPa
Elongation in 2 inch (50 mm): 24%
