Name: GCr15 Cold Rolled Bearing Steel Strip
Brand: Hengtaifeng

Overview

GCr15 is a high-carbon chromium bearing steel designation, often compared with 52100, SUJ2 and 100Cr6. Comparable names do not prove interchangeability; chemistry, cleanliness, carbide condition, delivery state and acceptance tests must be checked against the governing standard.

Chemical Composition

Element	C	Si	Mn	Cr	P (max)	S (max)
%	0.95-1.05	0.15-0.35	0.25-0.45	1.40-1.65	0.025	0.025

Mechanical Properties

Condition	Hardness	Tensile Strength
Annealed (spheroidized)	≤207 HB	≤750 MPa
Hardened & Tempered	60-65 HRC	2000-2500 MPa

Composition, hardness and mechanical-property tables are grade references, not guaranteed supply values. Verify the applicable standard edition, product form, condition and order-specific acceptance criteria.

Typical Applications

Bearing Rings

Inner and outer rings for ball and roller bearings. Ultra-clean steel with controlled inclusion level for long fatigue life.

Ball & Roller Bearings

Precision balls and rollers. Uniform carbide distribution ensures consistent contact stress performance at 60-65 HRC.

Precision Instruments

Gauge blocks, valve components, and linear guides. Excellent dimensional stability and wear resistance after heat treatment.

How to Specify GCr15 Strip

State GCr15 or the accepted equivalent standard
Provide thickness, width and dimensional tolerance
Choose the required delivery condition and surface finish
Describe the bearing component, edge and testing requirements
Include order quantity and destination for quotation review
