Processing performance and heat treatment

409L stainless steel has good processing performance, the starting temperature of hot processing is 1100-1150℃, and the coiling temperature is 600℃. The annealing temperature of hot-rolled strip in the bell furnace is 830-870℃, and the continuous annealing and pickling temperature of cold-rolled strip in the cold line or mixed line should be controlled at 860±10℃. The current input should be small during welding to avoid excessive grain growth and reduce the plastic toughness of the weld and heat-affected zone.

409L stainless steel coil application field

Widely used in automobile exhaust systems. Due to its excellent corrosion resistance and high temperature resistance, it is used to extend the life of the car and achieve lightweighting of the car.
