Surface Roughness and Tolerance Class: Navigating the Critical Relationship in Quality Control

Surface roughness is an important technical index that reflects the microgeometric errors of a part’s surface and is a key factor in assessing surface quality. The selection of surface roughness is directly linked to a product’s quality, service life, and production cost. There are th... Read More

Understanding the Applications of Quenching, Tempering, Normalizing, and Annealing

1. Quenching 1. What is quenching?Quenching is a heat treatment process used for steel. In this process, the steel is heated to a temperature above the critical temperature Ac3 (for hypereutectoid steel) or Ac1 (for hypereutectoid steel). It is then kept at this temperature for a period of time t... Read More
