Types of Stainless Steel
Stainless steels can be produced with five distinct crystalline structures: ferritic, austenitic, martensitic, duplex, and precipitation hardening. Ferritic Ferritic stainless steels contain iron, carbon, and between 10.5 and 18 percent chromium. They may contain other alloying elements such as m...Read more -
Heat treatment for stainless steel
Spheroidizing Spheroidizing occurs when carbon steel is heated to approximately 1290°F for 30 hours. The layers of cementite in the pearlite microstructure are transformed into spheroid, resulting in the softest and most ductile form of steel. Full annealing Carbon steel is annealed by f...Read more -
How scrap metal is recycled and reused
