1.4521 stainless steel chemical composition

The heat treatment process of 1.4521 stainless steel mainly includes:
Solution treatment: carried out at a temperature of 800~1050°C, followed by rapid cooling
Annealing treatment: used to eliminate processing stress, restore the ductility of the material, and improve its mechanical properties. Annealing treatment is usually carried out in the range of 800°C to 900°C for about 1-2 hours. After annealing, it should be slowly cooled, preferably in the furnace, to avoid embrittlement of the material.

1.4521 stainless steel is available in different forms, including:
Sheets: commonly used in the manufacture of chemical containers, gas heat exchangers, food processing equipment, etc.
Pipes: suitable for the manufacture of pipelines, petrochemical equipment, etc.
Bars: used for the manufacture of valves, bearings, etc.
Wires: used for welding, the manufacture of bolts and fasteners, etc.
