DIN HI steel is a European specified steel for use in pressure vessels, boilers and heat exchangers.
The composition of DIN HI steel makes it ideal for applications where elevated working temperatures are the norm and the material is used by fabricators throughout the oil, gas and petrochemical industry.
DIN HI steel is a normalized carbon alloy steel and is available ex-stock from our warehouse with mill certification and stamping.
