Description

The 304 / 304L grade of austenitic chromium-nickel stainless steel tubes and pipes are the most versatile and widely used steel piping products. Type 304 / 304L stainless steel is a very low carbon steel that exhibits excellent corrosion resistance. Also, it offers superior resistance to intergranular corrosion following welding or stress relieving. Besides, the 304 and 304L type grades exhibit good machine ability and excellent weld-ability characteristics with or without filler metals.

Other advantages are its resistance to oxidation, excellent form ability, ease of fabrication and cleaning, excellent strength to weight ratio and good toughness at cryogenic temperatures.

Centerway steel co.,ltd can provide 304/304l stainless steel pipes and plates of various standards, passed ISO9001, SGS and other certificates, accept third-party testing, has complete testing and testing facilities, from product development, raw material supply, production process management, etc. in accordance with international quality The system standards are standardized to provide customers with satisfactory pre-sale, in-sale and after-sale services.
