Jiangsu Liangyi is an ISO 9001:2015-certified nickel-alloy forging manufacturer in China supplying Incoloy 945 / UNS N09945 (Alloy 945) forged bars, rings, flanges, valve bodies and wellhead parts to oil & gas, subsea, marine, chemical and power projects in India and worldwide, to ASTM B637 and manufactured to API 6A and NACE MR0175 / ISO 15156-3 requirements.
Why Incoloy 945 / UNS N09945 for Indian oil & gas and chemical projects
Incoloy 945 is a precipitation-hardenable Ni-Fe-Cr superalloy (4447% Ni) with 895 MPa yield, 1035 MPa tensile and best-in-class resistance to sulfide stress cracking (SSC) and stress-corrosion cracking (SCC) in HS/CO/chloride sour service. For India's offshore and onshore sour gas, refinery and chemical projects, N09945 suits high-pressure wellhead and Christmas-tree parts, subsea valve bodies, tubing/casing hangers and downhole tools where lesser alloys fail.
