Product Description
65Mn steel is a Chinese GB standard spring steel grade, Manganese (Mn) improves hardenability, so the strength, hardness, elasticity and hardenability are higher than that of 65# steel, but it has overheat sensitivity and temper brittleness. Water quenching tends to form cracks. The annealed state has good machinability, low cold deformation plasticity, and poor weldability.
Application
65Mn high carbon steel is a widely used Chinese steel with many applications, more prevalently for making kitchen knives. It is the steel we prefer making our handmade kitchen knives. With a hardness of 58 HRc (28 to 34 HRc in its raw form) on the Rockwell hardness scale, 65Mn steel is ideal for making resilient blades.
