Common Hardness Comparison Table | Most Complete Collection

HV, HB, and HRC are all measurements of hardness used in materials testing. Let’s break them down: 1)HV Hardness (Vickers Hardness): HV hardness is a measure of a material’s resistance to indentation. It is determined by applying a known load to the surface of the material using a dia... Read More

Normalizing, annealing, quenching, tempering.

The difference between annealing and tempering is:Simply put, annealing means not having hardness, and tempering still retains a certain hardness. Tempering:     The structure obtained by high temperature tempering is tempered sorbite. Generally, tempering is not used alone. The main purpose of t... Read More
