Recently, Pangang's first roll of high-speed and strong beam steel 800L successfully rolled off the production line at Xichang Steel and Vanadium hot rolling production line, marking that Pangang has a new generation of high-speed and strong beam steel production capabilities.
High-strength automotive beam steel is mainly used to process commercial vehicle beams. Lightweighting is an important measure to reduce exhaust emissions and energy consumption in the automotive field, improving the strength of steel plates is an important way to reduce plate thickness. 800L is the latest generation of high-performance beam steel and a key product for domestic steel companies.
The processing technology of automobile beam steel is stamping and bending, which requires the beam steel to have strong toughness, fatigue resistance, and cold formability. In view of this, Pangang combined its own resource attributes, used vanadium and titanium as composite micro-alloying elements, carried out composition design and key process technology research, and formed the key control technology of 800L girder steel. Pangang's 800L girder steel product has been innovatively researched on the basis of existing titanium micro-alloy girder steel, its performance indicators have simultaneously improved strength toughness, and plasticity, and can adapt to various high cold climates.
The rollout of Pangang's high-strength beam steel 800L makes Pangang one of the first domestic companies to carry out product certification of this brand, which will help Pangang expand its product market.
