Mar-X is a precipitation-hardening, stainless steel with excellent corrosion resistance for both atmospheric and chemical attack. The heat response characteristics of this grade provide especially good welding characteristics. Absence of hardening in the weld heat-affected zone (HAZ) offers improved blending characteristics and reduced cracking potential in welded areas. The material is supplied in the solution-treated condition with a hardness of approximately 321 HB (34 HRC). It may be age hardened with a simple thermal treatment to a hardness of 40+ HRC. This datasheet provides information on composition, physical properties, and hardness. It also includes information on heat treating, machining, joining, and surface treatment. Filing Code: SS-922. Producer or source: A. Finkl & Sons Company.
