Duplex stainless steel is a kind of stainless steel material. They are called biphasic (or austenite-ferrite) because their metallurgical structure consists of two phases, with almost equal proportions of austenite and ferrite. These materials have improved corrosion resistance, particularly chloride stress corrosion and chloride pitting, and have higher strength than standard austenitic stainless steels such as SS304 or SS316. Compared with austenitic stainless steel, the main difference in composition of duplex steel is the chromium content of 20-28% higher; Molybdenum content is high, up to 5%; The nickel content was reduced to 9% and the nitrogen content was reduced to 0.05-0.50%. Both low nickel content and high strength are significantly cost effective.

Copper pipe is also known as red copper pipe. A non - ferrous metal pipe, is pressed and drawn seamless pipe. Copper pipe has the characteristics of good electrical conductivity, thermal conductivity, electrical accessories and heat dissipation accessories of the main material, and become the modern contractor in all residential commercial housing water pipe, heating, cooling pipe installation of the first choice. Copper pipe corrosion resistance is strong, not easy to oxidation, and some liquid substances are not easy to react with chemical, easy to bend shape.

Aluminum pipe is a kind of non-ferrous metal pipe, refers to pure aluminum or aluminum alloy extrusion processing along its longitudinal length of hollow metal tubular material, can have one or more closed through holes, wall thickness, uniform cross section, in linear shape or into a roll delivery. Widely used in automobile, ship, aerospace, aviation, electrical appliances, agriculture, electromechanical, household and other industries

Sus201/201 stainless steel is a widely used precipitation hardening grade, high hardness, high strength, good corrosion resistance. Its performance is similar to that of SS302 stainless steel.
SS202 machinability to produce long rubber chip. It can also be processed in the annealed state. For full martensitic transformation and heat treatment, the material must be immersed at 1038°C(1900°F) for 30 min and cooled below 16°C(60°F). Do not use oxyacetylene welding connection. 202 steel material can be welded by ordinary fusion resistance method. SS 202 has good toughness at low temperature.
Grade 202 or 201 materials can be made into rolls, plates, strips, lines, tubes, profiles, bars, angles, etc.
