China 316L stainless steel pipe manufacturers 316, 316L, 321, 310S stainless steel tube
HAOSTEEL is one of the most professional manufacturer and supplier of stainless steel Tube. Stainless steel tube can be divided into seamless tube and welded tube according to production mode. Seamless tube can be divided into hot rolled tube, cold rolled tube, cold drawn pipe and extruded tube.The welded pipe is divided into straight welded pipe and spiral welded tube.
Description:
316L stainless steel features
1) cold rolled products have good gloss and beautiful appearance;
2) excellent corrosion resistance, especially pitting corrosion resistance, due to the addition of Mo;
3) excellent high-temperature strength
4) excellent working hardenability (weak magnetism after processing)
5) no magnetism in the solid solution state;
