The 10CrMo910, with increased chromium and molybdenum, provides greater heat and corrosion resistance than 13CrMo45 and 16Mo3.
The material is also a pressure vessel grade steel intended for use in elevated temperature service. Masteel delivers 10CrMo910 to fabricators serving the oil and gas sector.
In addition, the steel has good weldability and is provided under the EN 10028 standard.
Technical information is given below for 10CrMo910.
