HV Hardness of metal machined parts
HV Hardness is the vickers hardness, and HRC is the representation of rockwell hardness.Their differences are mainly in the hardness test, the indentation shape is different. The conversion between HV and Mpa Load 49~980 N,The conical diamond with the Angle of 136 degrees is pressed into the surface of the material,After keeping time,Measure the […]
Heat treatment is also important to machined parts
Everyone know that heat treatment is important to metal machined parts. We handle a project for automotive parts recently, the part material is 16Mncr5, heat treat requirements on print : tensile strength.800-950Mpa, Surface Hardness 500HV1. There are at least three ways to meet this heat treatment requirements as below. 1. Hardened parts at 900 C and […]
QPQ Nitriding
Do you know QPQ Nitriding? QPQ Nitriding is a process for producing a thin, high-hardness case that is wear and corrosion resistant. QPQ Nitriding widely used in industry for decades, is mainly used to improve the abrasion resistance of steel, cast iron, stainless steel and other materials, and to improve the fatigue strength, particularly in […]
