Annealing process

The process of heating metal or alloy to a suitable temperature, holding a certain period of time and then slowly cooling is called annealing. The essence of annealing is to turn the steel into pearlite after austenitizing, and the microstructure after annealing is close to the equilibrium microstructure. The purpose of annealing: (1) reduce the…

Induction heat treatment instead of carburizing gradually

Nowadays, the demand for environmental protection is higher and higher. China has taken environmental protection as a basic national policy, and began to promote cleaner production, requiring the implementation of green heat treatment, production of clean products. Implementation of green heat treatment, the most fundamental is for the sustainable development of mankind. We should make…

Carburizing and nitriding

Carburizing and nitriding

Carburizing and nitriding generally refer to surface chemical heat treatment of steel. Carburizing must be made of low carbon steel or low carbon alloy steel. It can be divided into solid, liquid and gas carburizing three kinds. Widely used gas carburizing, heating temperature of 900-950 degrees celsius. Carburizing depth mainly depends on holding time, generally…
