Yuhong Group has been dealing with Stainless Steel / Duplex Steel / Nickel Steel Seamless Tubes for more than 10 years, selling more than 80,000 tons of Stainless Steel / Duplex Steel / Nickel Steel Seamless Tubes every year. Our customers have covered 45 countries. Our seamless stainless steel pipes are widely used in mining, energy, petrochemical, chemical, food mill, paper mill, gas and fluid industries, etc. ANSI B16.10: B16.19 Sch 5s, Sch 10s, Sch 20, Sch 30, Sch 40s, Sch 60, Sch 80s, XS, Sch 100, Sch 120, Sch 160, XXS.
Carpenter 20 B729 tubing manufactured to ASTM B729 specifications is typically supplied in a stabilized annealed condition. As one of the foremost manufacturers of alloy 20 welded tubing, we recommend that these tubes be used in applications that are susceptible to pitting and chloride corrosion. In fact, we strongly recommend the use of Alloy 20 tubing in areas where Grade 316 alloys are susceptible to stress-related corrosion cracking. The difference between alloy 20 and alloy 20cb3 tubes is that specified CB3 tubes have niobium added to their alloy to make them more stable.
