Rubber machine screw Details
Rubber machine screw:
Nitriding brittleness:< = 一级
Chromium coating thickness:0.05～0.10mm
Application: rubber machine, rubber manufacturing machinery
Specs: bore Φ14-Φ300 X 8000mm
Nitrogen treatment: surface hardness>1000H, thickness: 0.5~0.8mm, Nitriding brittleness: ≤2, Alloy hardness: HRC56°～65°(alloy uses nickel base alloy)
1. Abrasion resistant, corrosion resistant.
2. With special treatment, it can effectively increase the abrasion resistance, extend the lifespan.
3.Corrosion resistance,abrasion resistance
4. The heat treatment uses nitriding treatment, chromium plating, high-frequency quenching, wear-resisting bimetallic layer, vacuum hardening and many other methods.
