Uginox MA3M (X38CrMo14, No. 1.4419) is an age-hardenable martensitic stainless steel, mostly used where a sharp edge for cutting is needed. The molybdenum-containing MA3M and Ma5MV grades can be used for kitchen knife and other food preparation blades due to their corrosion resistance and the possibility of achieving high hardness levels in the quenched and tempered condition. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-1017. Producer or source: Arcelor Stainless Processing LLC.
