hardox 450 chemical composition size list with price
On 18th December, 2019, BBN Group decorated the office Hardox 450 chemical composition building with many kinds of pendant. There were christmas trees, gifts and snowflakes in the logo wall. At the same time, we made a video at the Zhengzhou office to celebrate the coming Christmas holiday. Our Hardox 450 chemical composition oversea sales team and market delevopment team wish you Merry Christmas and Happy New Year. Besides, we prepare some meaningful gifts for our old customers.
The wear-resistant composite plate, Hardox 450 chemical composition should be pre heat treated to eliminate the residual stress produced in the machining process. If conditions permit, vacuum heating quenching and cryogenic treatment after quenching should be selected as far as possible. On the premise of ensuring the hardness of steel plate, pre cooling, step cooling and quenching or high temperature quenching should be selected as far as possible. For some wear-resistant composite plates, pre heat treatment, aging heat treatment and quenching, tempering and nitriding heat treatment can be used to control the accuracy of the wear-resistant composite plate.
