201&202 Stainless Steel Square Tube
Description
201 stainless steel square tube
Brief introduction of 201 material
Type 201 is an austenitic chromium-nickel-manganese stainless steel. It can be used in most applications as a substitute for 301. Type 201 is nonmagnetic in the annealed condition, but becomes slightly magnetic when cold worked. The rate of work hardening is similar to type 301, although type 201 develops somewhat higher yield strength while retaining equal ductility when cold worked. Toughness at low temperatures is excellent.
202 stainless steel square tube
Brief introduction of 202 material
202 stainless steel is one of the 200 series stainless steel. 200 series stainless steel has low nickel (4%-6%) and high manganese (7.5%-10%). It's widely used in building decoration, municipal engineering, highway guardrail, hotel facilities, shopping malls, vitreous armrest, public facilities, etc.
201/202 stainlesss steel tube Application
Typically used for: food processing equipment, appliances, sinks, restaurant equipment, cooking utensils, hardware, automotive trim, architectural applications, buses, trailers, fastener parts and hose clamps.
