ZGCr15 Electroslag Remelting Steel & High-Carbon-Chrome-Bearing-Steel
Description
ZGCr15 is made of GCr15 by the ectro-slag remelting method, which is also called the electroslag remelting steel.
ZGCr15 has fewer impurities and better comprehensive performance than GCr15. Its excellent performance includes:
- Better cutting performance after annealing;
- High and uniformity hardness after quenching and tempering;
- High wear resistance ability;
- High anti-fatigue strength;
- Better thermal processing performance.
So, ZGCr15 is the most widely adopted steel for bearing rolling elements and sleeve drawings.
