the service hardness of pre-hardened steel
the service hardness of pre-hardened steel is usually within the range of 30—42HRC, wherein the cutting property is not good under high hardness, […]
Select a suitable coating for mold component
A popular practice of moldmakers and injection molders is to coat mold components as an attempt to increase the durability and achieve longer life while reducing maintenance and operational costs. This practice is certainly plausible, as it often falls short of providing the expected results and reduces the potential for maximum cost savings. [...]
Define hardness,heat treatment and holding temperature
Hardness: Hardness is the measurement of the steel’s resistance to indentation by pressing into the surface of the steel a specific object—such as a steel or molybdenum ball or diamond indenter—using very specific loads. […]
