All the tooling will be made on our own expense within 3 days.10 Grease nipples11 Hose clampsCertificatesHeat 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.Chemical and mechanical properties of steelCarbon spring steel C67 EN 10132-4: 2000Chemical components of Carbon spring steel C67SCSiMnPSNiCrMoCuother0.65-0.730.15-0.350.60-0.90≤0.025≤0.025≤0.400≤0.400≤0.100-Mechanical properties of C67SCondition of deliverySoft annealed (+A) or soft annealed and slightly rerolled (+LC)Quenched and tempered (+QT)0,2% proof stress Rp0,2 [N/mm²]max. 5101200 - 1900Tensile strength Rm [N/mm²]max. 640Fracture elongation A80 [%]min. 16Hardness [HV]max. 200370 - 580Hardness [HRB]max. 92Hardness [HRC]38,5 - 54Typical hardness values (HV) for quenched and tempered materials at different thickness rangesEffective thickness [mm]0,30<=0,500,50<=0,750,75<=1,001,00<=1,501,50<=2,002,00<=3,00Hardness [HV]485 - 535465 - 515455 - 505445 - 495425 - 475415 - 465Stainless Steel SS4202Cr13, which is equivalent to 420, is frequently used for SS retaining rings. The hardness reaches HRC 44-50 after heat treatment.
