321 Stainless Steel Strip is an austenitic chromium-nickel-manganese stainless steel developed in the 1950s as a result of global nickel shortages. Manganese and nitrogen are partially substituted for nickel in the Type 321 composition.The following is the chemical composition of austenitic, non-magnetic stainless steel 321. It is composed of chromium (16% - 18%) and nickel (3.5% - 5.5%). It has a higher manganese (5.5%-7.5%) and nitrogen content, but a lower nickel content than type 304 steel.
317L Stainless Steel Strip is an austenitic chromium-nickel-manganese stainless steel developed in the 1950s as a result of global nickel shortages. Manganese and nitrogen are partially substituted for nickel in the Type 201 composition.The following is the chemical composition of austenitic, non-magnetic stainless steel 317. It is composed of chromium (16% - 18%) and nickel (3.5% - 5.5%). It has a higher manganese (5.5%-7.5%) and nitrogen content.
317 Stainless Steel Strip is an austenitic chromium-nickel-manganese stainless steel developed in the 1950s as a result of global nickel shortages. Manganese and nitrogen are partially substituted for nickel in the Type 317 composition.The following is the chemical composition of austenitic, non-magnetic stainless steel 317.
