ASTM A213 AISI 321 Stainless Steel Tube UNS N32100 EN 10216 – 5 1.4541 is a stabilized stainless steel which offers as its main advantage an excellent resistance to intergranular corrosion following exposure to temperature in the chromium carbide precipitation range from 800 to 1500°F (427 to 816°C). Alloy 321 stainless steel tubing is stabilized against chromium carbide formation by the addition of titanium. 321 321H stainless steel is basically from 304 stainless steel. They different by a very very small addition of Titanium. The real difference is their carbon content. The higher the carbon content the greater the yield strength. 321 stainless steel has advantages in high temperature environment due to its excellent mechanical properties. Compared with 304 alloy, 321 stainless steel has better ductility and resistance to stress fracture. In addition, 304L can also be used for anti-sensitization and intergranular corrosion.A limitation with 321 is that titanium does not transfer well across a high…

ASTM A789 ASME SA 789 SAF 2507 UNS S32750 (EN 10216 – 5 1.4410) Stainless Steel is super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment. The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion. S32750 Stainless Steel have enhanced pitting and crevice corrosion resistance when compared with 300-series austenitic stainless steel or conventional duplex alloys. This can be attributed to the enhanced levels of chromium, molybdenum and nitrogen found in these materials. Alloy 2507 is the most common “super” duplex grade. Guanyu Steel Tube Super Duplex 2507 Stainless Steel Pipe Corrosion Resistance 1. Usual CorrosiveThe higher chromium and molybdenum content of SAF 2507 has a strong resistance to overall corrosion of organic acids such as formic acid, acetic acid, etc. The SAF2507 alloy has a strong resistance to inorganic…

ASTM A789 ASME SA 789 S32205 2205 Duplex Tubing is a 22% chromium, 3% molybdenum, 5-6% nickel, nitrogen alloyed duplex stainless steel with high general, localized, and stress corrosion resistance properties in addition to high strength and excellent impact toughness. S32205 is very similar with S31803. The difference is on Chemical composition. Usally we use S32205 replace S31803. Alloy 2205 Duplex Tubing provides pitting and crevice corrosion resistance superior to 316L or 317L austenitic stainless steel in almost all corrosive media. It also has high corrosion and erosion fatigue properties as well as lower thermal expansion and higher thermal conductivity than austenitic.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 austenitic alloy ease of fabrication and corrosion resistance. ASTM A789 ASME SA 789 S32205 Duplex Stainless Steel is a nitrogen enhanced duplex stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steel. “Duplex” describes a family…
