13CrMo4-5, 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.
