Quenching structure of Crl3 stainless steel

2Crl3 stainless steel is a hypoeutectoid steel. The temperature is raised to the austenite transformation temperature and kept for a period of time to make its austenite nucleate more evenly. Then, it is cooled rapidly. This process is called foreign fire. The MS of Crl3 type stainless steel is...

Development status of Crl3 stainless steel

Li Yupeng and others found that under the same quenching and tempering process, the tensile strength of 2Cr13 Steel after isothermal annealing can be more than 850mpa, and the impact energy aku2 value can also be increased by 21.8%, reaching 75.5j. Under the process of 1000 ° C +...

Annealing microstructure of Crl3 stainless steel

Generally speaking, as cast alloy steel is mostly ferritic + carbide phase, so is 2Crl3 stainless steel, which needs further annealing treatment. 2Crl3 stainless steel is a medium low carbon alloy steel. Relevant data show that under the traditional 750-800 ° C heat preservation for 2-6h and air cooling,...

Microstructure of tempered Crl3 stainless steel

The tempering process is a quenching and tempering step after the previous heat treatment. Although the martensite in the structure after quenching is very “hard”, it is all caused by dislocation distortion due to supersaturation of carbides. Such structure is unstable due to internal stress. In order to obtain...
