AISI 410
Typically supplied in the hardened and double tempered condition (197-237HBW/*22 HRC max)
Grade is typically used for pressure containing applications such as valve bodies, tubing hangers, it is also used for valve gates and stems.
Good weldability, and so may be welded to itself or weld inlayed. The grade does require a post weld heat treatment at 621oC min in order to meet sour service (NACE MR017/ ISO 15156) requirements.
Non-NACE condition hardened and single tempered product can be supplied where applications call for 105K min yield, however this condition significantly reduces the impact toughness.
