Analysis of commonly used wear-resistance in Shot blasting machine industry-2

1. 65Mn:
65 Mn is a high carbon manganese steel with a carbon content of 0.65%. The front 65 indicates a nominal carbon content of 0.65%. It has high hardness and good elasticity, making it a material for processing springs, tools, and saw blades.
2. 16Mn:
16 Mn is a low-carbon manganese steel with a carbon content of 0.16%, The front 16 indicates a nominal carbon content of 0.16%. It has low hardness, and Softer material than 65 Mn; 16 Mn has better toughness than 65 Mn, and in some cases where toughness is required, 16 Mn may be more suitable. For example, when manufacturing components that need to withstand impact and vibration, the toughness of 16 Mn can reduce the risk of component fracture.
3. Difference:
Compared to 16 Mn, 65 Mn material is harder.
The hardness of steel is mainly related to its carbon content, in addition to its alloy content.
The higher the carbon content, the closer it is to iron, the higher the hardness, and the harder the material.
16Mn usually has a surface hardness of less than 1 degree HRC.
Before heat treatment, the surface hardness of 65Mn can reach around 10 degrees HRC. Properly treated 65Mn can reach around HRC60 degrees, greatly enhancing the hardness, deformation resistance, wear resistance, and ability of the steel plate.
16Mn and 65Mn both contain Mn elements, but 65MN achieves strong elasticity and fatigue resistance with the help of carbon and other elements. So 65Mn steel plate, also known as spring steel plate, while ordinary 16MN materials do not have these characteristics.
