Strong Metal participated in the 6th Heat Treatment Forum in Shenzhen

Stainless steels are generally heat-treated based on the stainless steel type and reasons for carrying out the treatment. Heat treatment methods, such as stress relieving, hardening and annealing, strengthen the ductility and corrosion resistance properties of the metal that is modified during fabrication, or generate hard structures capable of tolerating abrasion and high mechanical stresses.

​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.

The 72nd anniversary of our birth, the motherland is strong, the people have faith, and the prosperity is stronger and stronger!

The stainless steel bright annealing production line (BAL) of a steel mill is a large-scale production line designed and manufactured by a foreign company for bright annealing stainless steel strips. Its total height is 55m, and it can handle stainless steel plates with a width of 600 to 1250 mm and a thickness of 0.1 to 3.0 mm. belt.

MEPS raised its forecast for global stainless steel crude steel production growth in 2021. It is estimated that global stainless steel crude steel production will increase by 11% year-on-year to 56.5 million tons in 2021. Indonesia's production growth in the first quarter exceeded expectations, and China's strong growth supported the expected increase in supply.

[Summary Description] On July 31, the Foshan Metal Materials Industry Association (hereinafter referred to as the "Association") will hold the 2021 "Foshan Integrity, Brand Not Stone" Forum and the "Contract Abiding and Trustworthy" Enterprise Owners Conference (fourth Session) held a press conference at the Fourth Yellow Building He Hall of Tooling International Hotel (Foshan World Clothing Store). Guests at the conference included Foshan Federation of Industry and Commerce, Foshan City Federation of Industry and Commerce, Foshan Institute of Science and Technology, and Battery Energy Institute, etc. Taking the lead in organization, Foshan Yuanxinghong Welded Pipe Machinery Mould Co., Ltd., Foshan Zunxianxing Stainless Steel Co., Ltd. and other metal material industry representatives, Shichuang Technology was invited to attend this conference and participate in the corporate image brand of "Abiding by Contract and Respecting Credit" .
