42CrMo & 40Cr Wear-Resistant Forged Alloy Steel Parts for Marine Shaft Fittings
We manufacture high-quality forged alloy steel parts using 42CrMo and 40Cr, engineered for superior performance in marine shaft fittings and other shipbuilding applications. These wear-resistant steel components deliver exceptional strength, hardness, and fatigue resistance—ensuring reliable operation in harsh offshore environments.
Each part is forged to exact specifications, followed by precise heat treatment and mechanical testing, including tensile tests and impact tests, to guarantee consistent quality. Our forged marine parts are ideal for ship shafts, couplings, flanges, and custom shaft components.
