Heat treatment of bearing steel - strong metal heat treatment furnace
Bearing steel ingots are generally subjected to long-term diffusion annealing at a high temperature of 1200 ~ 1250 ℃ to improve carbide segregation. The atmosphere in the furnace should be controlled during hot working, the heating temperature of the billet should not be too high, and the holding time should not be too long to avoid serious decarburization. The final rolling (forging) temperature is usually between 800 and 900 ℃. If it is too high, it is easy to appear coarse network carbides, and if it is too low, it is easy to form rolling (forging) cracks. The finished rolled (forged) material should be quickly cooled to 650°C to prevent cementite from precipitating in a network on the grain boundary. If conditions permit, a controlled rolling process can be used. -

What are the advantages of stainless steel roofs?
The first large-scale high-end application of stainless steel in the roof was the Chrysler Building in New York built in 1930. It was the world's tallest building at that time. The roof and wall panels were made of 302 stainless steel, which is still shining today. -
