From Raw Material to Premium Product:Core Process Guarantee of Henan Xintengfei Cast Steel.

Casting Technology: The company adopts the sodium silicate sand casting process, which endows large gear castings with a dense internal structure.

Heat Treatment Process:In view of the material characteristics of ZG42CrMo, ZG40CrNi2Mo and other grades, the company has developed dedicated heat treatment process schemes. By precisely controlling heating temperature, holding time and cooling rate, it realizes the optimal matching of strength and toughness for castings.Full-process Quality Monitoring:From spectral analysis of incoming raw materials, casting process control, to mechanical property tests (tensile strength, impact energy, etc.) and non-destructive testing (UT, MT) after heat treatment, strict inspection points are set for every working procedure.This ensures the performance data of every delivered gear fully meets and even exceeds industry standards.

Customer Value: Reliability, Long Service Life and Comprehensive Cost Efficiency.

For end users, the significance of material selection lies in the value brought by the long-term and stable operation of equipment.The large gears supplied by Henan Xintengfei Cast Steel in materials such as ZG42CrMo and ZG40CrNi2Mo deliver core customer value as follows:

Ultra-high Reliability:Eliminate the risk of early failure through raw material control at the source and sophisticated manufacturing processes, ensure continuous and stable operation of main equipment, and reduce unplanned downtime.

Ultra-long Service Life:Excellent wear resistance and fatigue resistance significantly extend the gear replacement cycle, cutting long-term maintenance and replacement costs.

Comprehensive Cost: It delivers high cost performance. From the perspective of equipment life-cycle cost, its long service life, high reliability and low failure rate can create substantial economic benefits for customers.

Henan Xintengfei Cast Steel Co., Ltd. stated that the selection of materials is both a science and an art, supported by profound theoretical knowledge and rich practical experience. The company not only provides customers with high-quality large gear castings, but also strives to become customers’ technical partner. Tailored to different working conditions and design requirements, it jointly promotes the reliability of China's heavy equipment manufacturing industry.
