Hardening
High-frequency induction hardening guarantees the surface hardness and optimum strength of the material, which makes the shaft highly durable and resistant to abrasion. We can supply several conditions as follows:
1,Hard chrome plated (surface without heat treatment)
2,High-frequency induction hardened hard chrome plated
3,Quenched and Tempered
4,Induction hardened with Q&T
Centerless grinding
Our grinding lines work at high processing speeds with optimum efficiency. Depending on material and diameter requirements, surface qualities with roughness specifications up to Ra 0.2 µm can be obtained.
Surface treatment
By hard chrome plating, your components obtain a high resistance to corrosion and wear. This means high endurance over the entire life of the product. Usually, the thickness of hard chrome plating is 10μm ~ 15μm.Resistance in front salt spray (fog) test environment according to the ASTM B-117-97 could be 36 hours.
Hard chrome plated rod (HRC 15-20)
Hardened and tempered chrome plated rod (HRC 28-30)
Induction and hardened chrome plated rod (HRC 55-60)
Polishing
We can guarantee you mirror-like polished surfaces with our optimal finish grinding method - without material loss.
