Stainless steel forged pipe fittings

UNS S31254 Pipe Fittings which is described as a 6 % Mo super austenitic stainless steel. These Duplex Steel UNS S31254 Butt Weld Fittings is a lustrous, silvery colored Molybdenum metal which has an abundance of 1.5 ppm in the earth¡¯s crust. Our Duplex Steel UNS S31254 Pipe Fittings is a high-alloy austenitic stainless steel developed for use in seawater and other aggressive chloride-bearing media. The driving force to the development of these Stainless Steel SMO 254 Buttweld Fittings was the sensitivity to inter-granular corrosion of existing austenitic steels which often contained 0.08 % – 0.10 % carbon. Our Duplex Steel F44 Buttweld Pipe Fittings combines moderately good mechanical strength and high ductility with excellent corrosion resistance in a variety of environments.

Grade 316 pipe bend also has given excellent service in potable water. Pitting and crevice corrosion may occur in waters with higher chloride content, and 2000 ppm is accepted as the upper limit. The higher molybdenum content of 316 make it significantly more corrosion resistant than grade 304.

Ordinary steel fittings are susceptible to chloride stress corrosion cracking. However, ASME SA815 Duplex Pipe Reducers are better because they inhibit deformation and avoid corrosion cracking even at high temperatures. UNS S31803 Duplex Steel Tee is said to have amazing resistance to toxicity and elasticity, so it is used in the gas desulfurization industry. WERKSTOFF NR. 1.4462 end caps are highly resistant to intergranular corrosion and are therefore used for termination connections.

Duplex 2205 is a duplex ferritic austenitic stainless steel containing approximately 22% chromium, 3% molybdenum and (5 to 6)% nickel. Duplex steel butt welded pipe fittings are also available in various forms, such as 45 degree, 90 degree long and short radius elbows, equal and unequal diameter tees, concentric and eccentric reducers, end caps, short pipe ends, and more.

It is ideal for food processing, chemical processing, and fluid transportation. The most common uses for stainless steel forged fittings are in food and fluid processing, as well as chemical applications. Stainless Steel 304 is the best choice for forged fittings because of its inherent properties.
