During continuous development, GBT 8162 40Cr seamless steel pipe also has a better promotion in performance, today BBN steel would like to introduce how to improve the hardenability of GBT 8162 40Cr seamless steel pipe.
The internal surface mechanical polishing of GBT 8162 40Cr seamless steel pipe covers rotary and linear polishing. The heat resistance of GBT 8162 40Cr seamless steel pipe refers to that under the high temperature, GBT 8162 40Cr seamless steel pipe has the properties of corrosion resistance, that is, thermal stability. At the same time, at high temperature, 40Cr pipe has sufficient strength, that is, thermal strength.
Manganese can improve the strength of GBT 8162 40Cr seamless steel pipe, weaken and eliminate the adverse effects of sulfur, and GBT 8162 40Cr seamless steel pipe can improve the hardenability.
After hardening, the GBT 8162 40Cr seamless steel pipe has been greatly improved in comprehensive performance, and gets obvious change in hardness. So, in the subsequent development process, the performance of GBT 8162 40Cr seamless steel pipe has also been better improved.
Just like you, 70% customers choose long-term cooperation with BBN steel not only for our good product and service quality, good reputation in the international market, but also for our experienced one-stop raw material supply and further steel processing!
