Chanathip Nickel Alloys & Plates produces forged fittings made from high-quality UNS N10276 alloy in the form of elbows, tees, reducers, couplings, caps and other forged shapes. Forging, machining, and heat treatment provide high strength, corrosion resistance, and dimensional accuracy. Employed in chemical plants, pollution control, marine applications, and any system conveying aggressive or mixed acids, these fittings provide integrity in adverse conditions. A pressure test and material test are applied to each fitting to provide safety and reliability in severe service.
Hastelloy C276 forging fittings have the same composition as the alloy: approximately 57% Ni, 15.5‑17% Mo, 14.5‑16.5% Cr, with Fe, W, Co and minor impurities. Mechanical properties are tensile up to ~790 MPa, yield strength ~ 355 MPa, elongation ~35‑45%, and good resistance. Forging enhances grain structure and pressure rating, providing strong performance in pressure class fittings. The alloy offers superior resistance to pitting, crevice corrosion, stress-corrosion cracking and maintains strength in oxidizing/reducing environments and high temperature environments.

Hastelloy C276 forged fittings are utilized in piping systems of chemical and petrochemical facilities, acid handling, marine and offshore facilities, flue gas scrubbers, and pollution control devices. They are applied where manifold elbows, reducers, or specialty forged shapes are required to pass corrosive media, high pressure, or thermal cycling. These fittings offer long service life where welded or wrought parts will be inferior. Uses include power generation, desalination, pharmaceuticals, and acid production. Their improved corrosion resistance and mechanical strength make them the best choice in high‑cost, high‑risk systems.
