Typical  201  Stainless  Steel  Welded  Tube

Type 201 stainless steel is the most common austenitic chromium-nickel stainless steel and is a variation of the classic more than 0.7Ni  stainless. Its properties provide corrosion resistance to a wide range of construction, upholstery,decoration etc.  Such as fencing,railing,safe door ,windows, gate fittings,inside staircases, furniture, sanitary wares, kitchenwares!

Typical  304  Stainless  Steel  Welded  Tube

Type 304 stainless steel is the most common austenitic chromium-nickel stainless steel and is a variation of the classic 18Cr8Ni stainless. Its properties provide corrosion resistance to a wide range of construction, upholstery,decoration etc.  Such as fencing,railing,safe door ,windows, gate fittings,inside staircases, furniture, sanitary wares, kitchenwares!
