Description
Duplex stainless steel tube(seamless tube and welded tube) can be divided into four types: low alloy, medium alloy , high alloy, and super duplex stainless steel type. The main characteristic of the duplex stainless steel tube is that its yield strength can reach 400-55OMPa, which is twice that of ordinary stainless steel, so it can save materials and reduce equipment manufacturing costs. In terms of corrosion resistance, especially for poor conditions of the medium (such as seawater and high chloride ion content), the resistance to pitting, crevice corrosion, stress corrosion, and corrosion fatigue of duplex stainless steels is significantly better than that of ordinary austenite, as good as high-alloy austenitic stainless steels.
Karnora can provide duplex stainless steel pipes and plates of various standards and grades, 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.

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.
