P235GH is a European specified steel for use in pressure vessels, boilers and heat exchangers. The composition of this 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. P235GH is a normalized carbon alloy steel and is available ex-stock from our warehouse with mill certification and stamping. This EN10028 steel grade supersedes the older BS and DIN standards (Grades BS 1501-161-360A and DIN H 1, respectively). The technical details are given in the tables below. P235GH – Chemical Composition The Chemical Composition of EN 10028 P235GH is given in the table below.
