What is the difference between 65' manganese steel and high carbon steel

Manganese steel is a kind of steel, is a kind of high-strength manganese resistant steel, mainly used to need to withstand impact, extrusion, material wear and other harsh working conditions, is a typical anti-wear steel, the as-cast structure is austenite plus carbide. After water quenching at about 1000°C, the structure is transformed into a single austenite or austenite with a small amount of carbide.

High carbon steel hardness is high, high manganese steel (spring steel) hardness is low, but the toughness is much better than high carbon steel, and the possibility of high carbon steel breaking is great when it withstands the same violent chop.

65Mn steel plate strength, hardness, elasticity and hardenability are higher than high carbon steel, with overheating sensitivity and tempering brittleness tendency, water quenching has a tendency to crack. The machinability of annealed state is reasonable, the cold deformation plasticity is low, and the weldability is poor. Moderately loaded plate springs, coil springs with a diameter of 7-20mm and spring washers. Spring ring. High wear resistance parts, such as grinding machine spindle, spring clamp, precision machine tool screw, cutter, spiral roller bearing sleeve ring, railway rail, etc.
