EN10028: Part2 :2006 is a euro norm standard relating to weldable pressure vessel grade alloy and non–alloy steels used in elevated temperature service.

The standard supersedes the old British and DIN standards. Chrome Molybdenum steels, with their higher temperature resistance, come under this standard and this section includes link to EN10028 chrome moly grades which are suitable for the fabrication of pressure vessels and boilers.

Chrome Molybdenum pressure vessel grade steels offers good corrosion resistance and weldability. We supply this material to fabricators who serve the major oil, petrochemical and gas companies.

Masteel stock EN 10028: 2: 2006 specified chrome moly steel which is shipped with test certification and stamping.

EN 10028 10CrMo910

10CrMo910, with increased molybdenum and chromium, provides greater heat and corrosion resistance than 16Mo3 & 13CrMo45.

Again the material is a pressure vessel grade steel for use in elevated temperature service. Masteel supplies 10CrMo910 to fabricators serving the oil and gas industry. The steel has good weldability and is offered under the EN 10028 standard.

Please refer to the technical information for 10CrMo910 below.

EN 10028 13CrMo45

13CrMo45 is chrome moly steel intended for use in the fabrication of weldable steel pressure vessels and boilers in elevated temperature service.

The material offers excellent performance with higher than normal temperature resistance and displays excellent anti-corrosive properties making it suitable steel for use in sour service environments. Popular with the oil, petrochemical and gas industries, 13CrMo45 is supplied under the EN 10028 euro norm standard.

EN 10028 16Mo3

16Mo3 is a EN10028 specified pressure vessel grade chrome molybdenum steel alloy for use in elevated working temperatures.

The material is used as a weldable steel in the fabrication of industrial boilers and steel pressurised vessels found in the oil, gas and chemical industry. Due to the materials chrome and molybdenum content, 16Mo3 has excellent heat resistance and corrosion resistant characteristics.

Grade 16Mo3 is available ex–stock from Masteel UK Limited and the material comes with test certification and stamping. Please refer to technical information for this grade below.
