EN P235GH European specified steel for use in pressure vessels,boilers and heat exchangers


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.

Table 1: Chemical Composition of EN 10028 P235GH

Element % by mass Element % by mass
Carbon (C) ≤0.16 Silicon (Si) ≤0.35
Manganese (Mn) 0.60 to 1.20 Phosphorous (P) (max) 0.025
Sulphur (S) (max) 0.015 Aluminium (Al) ≤0.020
Nitrogen (N) ≤0.012 Chromium (Cr) ≤0.30
Copper (Cu) ≤0.30 Molybdenum (Mo) ≤0.08
Niobium (Nb) ≤0.020 Nickel (Ni) ≤0.30
Titanium (Ti) (max) 0.03 Vanadium (V) ≤0.02

The combined quantities of Chromium, Copper and Molybdenum should not exceed 0.70% P235GH – Mechanical Properties The mechanical properties of EN 10028 P235GH are outlined in the table below.
