Duplex Steel Tube

Seamless S31803 3/4 Inch Super Duplex Steel Cold Drawn Tube Cold Drawn Tube: Super duplex stainless such as duplex is a mixed microstructure of austenite and ferrite which has improved strength over ferritic and austenitic steel grades. The main difference is super duplex has a higher molybdenum and chromium content which gives the material greater corrosion resistance. Super duplex has the same benefits as its counterpart - it has lower production costs when compared with

ASTM A789 Bright Annealing Duplex Steel For Industrial Tubing The advantages of duplex construction are resistant to stress corrosion cracking and high strength and ease of fabrication and corrosion resistance. The stainless steel tubing is generally produced by a cold-drawing process. A subsequent annealing process is required to eliminate residue stress and obtain improved softness and ductility. Industrial Tubing Application a) Petroleum b) Chemical industry c) Instrument

S31803/2205 1/4 Inch Duplex Stainless Steel Seamless Tube Stainless Steel Seamless Tube: Duplex S31803/2205 is a nitrogen enhanced duplex stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steels. The advantage of a duplex structure is that it combines the favorable qualities of a ferritic alloy (stress corrosion cracking resistance and high strength) with those of an austenitic alloy (ease of fabrication and
