Russian standard retaining rings, circlips,GOST 13942, GOST 13943
Carbon Spring Steel is the standard material for these internal retaining rings, and phosphate & Oil are the standard finishes. Stainless steel rings is made from SS420, SS304 or SS316.
Oriental Industry Co., Ltd is a leading manufacturer of retaining rings, circlips, snap rings, disc Spring washers, spring pins etc. in China. Our factory has obtained IATF16949 and ISO14001 certificates. The products can be applied to automotive industry, wind power machinery, engineering machinery, electrical tool, electrical appliance, general machinery etc. 80% of our products are exported to Europe, North America, South America and Asian & Pacific area. By introducing advanced equipment, using quality material and develop new process, Oriental Industry has set up a well-established production system. The utilization rate of raw material is improved from 30% to 70%. We have invested the advanced cold rolling mill which ensures the thickness tolerance within 0.05 mm.

Heat treatment and finish
- Austempering is applied to increase the mechanical property of our products. Our modern heat treatment equipment and skillful technicians guarantee each retaining ring within the mechanical properties required.
- The standard finish of carbon steel retaining rings is phosphate.
- Dacromet is available on request.
- Zinc plating is available, but is not recommended because of the risk of hydrogen brittleness.
- Stainless steel is polished into original color after heat treatment.

Stainless Steel SS420
2Cr13, which is equivalent to 420, is frequently used for SS retaining rings. The hardness reaches HRC 44-50 after heat treatment. This makes our SS retaining rings much excel the just stamped stainless retaining rings

* Ni is allowed to be equal to or less than 0.6.
Tensile Strength: σb (MPa):≥1274(130)
Yield strength σs (MPa):≥1176(120)
Elongation δ10 (%):≥5
reduction of cross section ψ (%):≥25
Hardness :hot rolling,≤321HB; cold rolling+heat treatment,≤321HB
