Charactteristics:

Flat Steel GCr15 Flats are of

Good hardening ability. Good wear resistance. Shadow depth of hardness

Harden from a temperature of 790-820oC, 820-860oC followed by water or oil quenching. Hardness after quenching is 63-67, 63-66 HRC.

Tempering temperature: 150-300oC. Hardness after tempering is 56-65 HRC.

 

Application:

Commom steel used to produce balls and rings of bearing. The product has characteristics of uniform-chemical composition, low percentage of harmful elements, high purity, well-distributed carbide, good surface quality. It also has characteristics of wide scope of plastic,stable heat-treatment quality, uniformand high hardness, high wear resistance,high strength of touching fatigue. It has excellent machining property afer spheroidize annealing.


The use of products The product is used to produce balls and rings of bearing. Future Development By rational rolling and cooling process, the product can be spheroidized on-line and can be used in drawing and machining directly by customers. By combining re-spheroidize annealing and re-crystallisation of semi-finished product, the steel wire process can be simplified.
