Product Advantages
Precision Machining
Measure and process using precision machine tools and measuring tools under strictly controlled environmental conditions.
High-quality Carbon Steel (35#/45#)
With long life, low heat generation, high hardness, high rigidity, low noise, high wear resistance and other characteristics.
Cost-effective
The use of high-quality carbon steel steel, after precision processing and forming, greatly improves the user experience.
Surface Treatment
ZINC
Electro-galvanizing is a traditional metal coating treatment technology that provides basic corrosion resistance to metal surfaces. The main advantages are good solderability and suitable contact resistance. Due to its good lubrication properties, cadmium plating is commonly used in aviation, aerospace, marine, and radio and electronic products. The plating layer protects the steel substrate from both mechanical and chemical protection, so its corrosion resistance is much better than zinc plating.
Parameter of Product
DIN 557 STANDARD
