42CrNiMo,18CrNiMo7-6  Free Forging forged hollow tubes 

Premium 42CrNiMo and 18CrNiMo7-6 Forged Hollow Tubes via Free Forging Process

We specialize in manufacturing high-quality forged hollow tubes using advanced free forging technology, with materials such as 42CrNiMo and 18CrNiMo7-6. These alloy steels are renowned for their outstanding strength, impact resistance, and fatigue performance, making them ideal for use in high-load industrial applications.

Precision Engineering for Demanding Applications

Our forged hollow tubes are widely used in wind turbine components, heavy-duty gearboxes, oil & gas equipment, and marine shafts. The free forging process ensures excellent metallurgical structure, uniform grain flow, and superior toughness. We can produce custom dimensions with or without inner bore machining, meeting exact customer specifications.

Strict Quality Control and International Standards

Each forged hollow tube is subjected to rigorous ultrasonic testing according to EN10228-3 or customer-specified standards. Our production process includes normalization, quenching & tempering, and accurate dimensional control. We are ISO9001, ISO14001, and ISO45001 certified, ensuring reliability and traceability throughout the production chain.
