What is the hardness of 16mo3 heat treatment

Pageviews:

The characteristic of niobium in 16Mo3 heat treatment etc. steel material is to increase the recrystallization temperature of austenite, so as to achieve the purpose of refining austenite grains. In general, the amount of niobium added in steel material is less than 0.05%, and the contribution of niobium above 0.05% to strengthening and toughening will no longer be obvious.

The Indian customer purchased our A516 Gr 70 pressure vessel steel plates to make tanks. They have very strict requirement for raw materials quality. For the A516 Gr 70 pressure vessel steel plates, they asked for Normalizing, 0℃ impact, A578 UT test, PWHT and so on tests, our Q/C department witness the production process with the technician from the customer company together. Meanwhile, we arrange BV inspection to check the quantity, spray mark, stamp on the A516 Gr 70 pressure vessel steel plates, and so on.

As the basic industry of the national economy, the steel industry is one of the most internationally competitive industries in my country. Li Xinchuang said: "During the new crown pneumonia epidemic, foreign steel companies have reduced production, suspended production or even shut down and withdrawn, while Chinese steel companies have basically maintained full capacity production, playing the role of 'ballast stone' in ensuring supply, protecting people's livelihood, and ensuring development."
