Duplex Stainless Steel Round Bar

Duplex stainless steel round bar is downstream processed to seamless pipe, fitting, flange, shaft, pump valve, member bar and so on, the final products are widely used in LNG liquefied natural gas, chemicals, ocean industry, petrochemical engineering and some high-end industries. 022Cr22Ni5Mo3N duplex stainless steel is a kind of ferrite to austenite stainless steel, belong to the second generation of duplex stainless steel in the alloy. In the early 1980 s, our country began to develop and 022Cr22Ni5Mo3N  duplex stainless steel is 00 cr22ni5mo3n duplex stainless steel, the microstructure of ferrite and austenite F A each account for about 50%. It combines ferrite and austenite is the most useful performance: ferrite phase steel has high strength and resistance to chloride stress corrosion performance, austenitic phase steel has good toughness and corrosion resistance. S31803, therefore, has the very good resistance to chloride stress corrosion cracking, are better than ferritic st...

ASTM A335 P22 alloy steel pipe

ASTM A335 P22 is the part of ASTM A335. ASTM A335 P22 alloy steel pipe shall be suitable for bending, flanging, and similar forming operations, and for fusion welding. Each length of pipe shall be subjected to the hydrostatic test. Also, each pipe shall be examined by a non-destructive examination method in accordance to the required practices. Inspection and Test: Ultrasonic inspection of seamless pipes Chemical Composition Inspection, Mechanical Properties Test(Tensile Strength,Yield Strength, Elongation, Flaring, Flattening, Bending, Hardness, Impact Test), Surface and Dimension Test,No-destructive Test, Hydrostatic Test. Surface treatment: Oil-dip, Varnish, Passivation, Phosphating, Shot Blasting. Both ends of each crate will indicate the order no., heat no., dimensions, weight and bundles or as requested. A335 is often called chrome moly pipe because of the chemical makeup of Molybdenum (Mo) and Chromium (Cr). Molybdenum increases the strength of steel as well as the elastic limit...
