Audited Supplier EN 10216-2 P235GH Seamless steel tubes for pressure purposes -Technical delivery conditions: Non-alloy and alloy steel tubes with specified elevated temperature properties.
Material P235GH is non-alloy steel with specified high temperature properties, good plasticity, toughness, cold bending and welding properties, specified in German and European standards DIN EN10216 and DIN EN 10028. EN 10216 Part 2 P235GH seamless tube is mainly for pressure purposesuch as the manufacturing of boilers and heat exchangers, steam tubes and pressure vessels.
P235GH is a normalized carbon low alloy steel. "P" means "weldable", "G" means "softened annealed" and "H" means "hardened". The main materials of EN10216-2 including: P235GH, P265GH, 16Mo3, 10CrMo55, 13CrMo45, 10CrMo910, 25CrMo4 and so on. P235GH's chemical composition makes it ideal for high-temperature applications, and the material is used by manufacturers in the oil, gas and petrochemical industries.
P235GH steel pipe is from European specification EN 10216-2 seamless steel tubes for pressure vessels,boilers,heat exchangers,super heaters,power piping,processing piping.For heat treatment,P235GH steel pipe does Normalized treatment with temperature 880 to 940 Deg.Centigrade.The cooling medium in Air.Rolling typies can be hot finished or cold finished.
Comparasion with P265GH steel pipe and P235GH steel pipe properties,chemical composition is very similar,only P265GH steel pipe need a higher carbon contains.Mechanical properties,P265GH steel pipe owned higher yield strength above 265 Mpa and tensile strength within 410-570 Mpa.P235GH steel pipe yield strength above 235 Mpa and tensile strength within 360-500 Mpa.Various diameters of P235GH steel pipe and P265GH steel pipes stock in our warehouse ready for shipment.
EN Specification alloy steel Tubes are used for high temperature service applications.Seamless Alloy Steel Tubes according to EN 10216-2 Grade P235GH are reheated and furnished in full annlealed,isothermal annealed or normalised quenched and tempered condition .EN 10216-2 Grade P235GH Alloy Steel Seamless Tubes have a typical chemistry with additions of max 0.30 Chromium and max 0.08 Molybdenum.Bearing minimum tensile strength of 360 Mpa and maximum tensile strength 500 Mpa, EN 10216-2 Grade P235GH Tubes have a minimum yield strength of 235 Mpa.
