Chanathip Nickel Alloys & Plates is a top manufacturer of Duplex Steel S32205 forged fittings in Bangkok, Thailand. We offer a wide range of socket weld and threaded forged fittings, including elbows, tees, couplings, plugs, and unions. Made to meet ASME B16.11 and MSS SP-79 standards, these fittings are produced through precision forging and machining processes, followed by solution annealing. Our forged fittings are recognized for their ability to handle high pressure, dimensional accuracy, and excellent corrosion resistance. These products serve essential industries such as oil & gas, petrochemicals, power generation, and marine applications both locally and for export.
S32205 forged fittings include about 22% chromium, 5–6% nickel, 3% molybdenum, and up to 0.20% nitrogen. Carbon, sulfur, and phosphorus levels are kept very low. The duplex microstructure gives them high mechanical performance: tensile strength ranges from 620 to 700 MPa, yield strength exceeds 450 MPa, elongation is typically above 25%, and hardness remains below 290 HB. Forging improves grain structure and strength, making these fittings perfect for high-pressure environments. They also offer superior corrosion resistance to pitting, crevice, and stress corrosion cracking compared to austenitic stainless steel.

Duplex Steel S32205 forged fittings are perfect for high-pressure and corrosive piping systems. They are commonly found in chemical processing plants, oil refineries, offshore platforms, and power plants. Typical applications include connecting instrumentation lines, joining small-diameter process piping, and ending pipelines with threaded or socket weld connections. These fittings are also used in desalination units, water treatment facilities, and fire suppression systems. Their strength and corrosion resistance make them ideal for tough service conditions that involve chlorides, sulfides, and acidic media. Easy to maintain and robust, these fittings are crucial in high-stakes and high-integrity piping systems.
