Custom Alloy Steel Forgings – 42CrMo, 30CrNiMo8 Shafts, flanges,
gear blanks for Wind Power Turbines
We produce custom alloy steel forgings in 42CrMo and 30CrNiMo8, tailored for wind power turbine components such as main shafts, flanges, and gear blanks. With over 25 years of open die forging experience, we provide high-strength, fatigue-resistant parts engineered to
meet the demanding requirements of wind energy applications.
Our forgings are available in non-standard sizes, support small batch production, and include material certificates (EN10204 3.1/3.2). We export regularly to Europe and offer in-house CNC rough machining and quality inspection to ensure reliable, on-time delivery.

We provide rough-machined large alloy steel forgings that have
undergone precise heat treatment processes such as annealing and
tempering. These components are ideal for further processing in
demanding applications across wind power, mining, energy, and heavy
machinery industries.
