321 stainless steel coil is a titanium stabilized chromium nickel austenitic stainless steel with corrosion resistance similar to 304/304L. This grade is typically used in the 800-1500˚F temperature range where it is stabilized against chromium carbide pr
316 stainless steel, 18cr-12ni-2.5 Mo due to the addition of Mo, so its corrosion resistance, atmospheric corrosion resistance and high temperature strength is particularly good, can be used in caustic conditions.
The black tube is made from hot rolled steel strip, so the application scope of the tube is greatly expanded. It is mainly used for construction, machinery manufacturing, shipbuilding, steel construction projects, solar power support, steel structure engi
