Product Description Product DescriptionAlloy Steel 52100, as known as AISI 52100, contains a high level of carbon and chromium. This alloy offers users good machinability, as well as forming through conventional methods. The hardening of Alloy Steel 52100 can be achieved by cold working, heating, and quenching.Chemical Composition (%)GradesCSiMnPSCrMoCuNiGCr15/521000.95-1.050.15-0.350.2-0.4≤0.027≤0.021.3-1.65≤0.1≤0.25≤0.3GCr15SiMn0.95-1.050.45-0.750.95-1.25≤0.025≤0.0251.4-1.65≤0.1≤0.25≤0.3100Cr60.95-1.050.15-0.350.25-0.45≤0.025≤0.0251.4-1.65≤0.08≤0.25≤0.3440C0.9-1.00.800.80≤0.035≤0.03016-18≤0.75≤0.25≤0.60100CrMn61.050.751.250.0250.0251.650.10.250.3Heat TreatmentQuenchingTemperingHeating Temperature/oCCoolingHardness/HRCHeating Temperature/oCCoolingHardness/HRC830-850Oil62-65150-190Air58-62Heat Treatment for ASTM 52100 Bearing Steel.ASTM/AISI 52100 alloy bearing steel is heated at 816°C followed by quenching in oil. Before performing this process, it issubjected to normalizing heat treatment at 872°C followed by slowly cooling in order to reduce the machining stress.Hot WorkingAISI 52100 bearing steels alloy can be hot worked at 205 to 538°C.Cold WorkingAISI 52100 bearing steel can be cold worked using conventional techniques in the annealed or normalized conditions.AnnealingFor spheroidize anneale, the following isothermal anneal is recommended:* 1500oF (815oC) for 3 hours* 1350oF (735oC) for 4 hours* 1250oF (675oC) for 3 hours* Slow cool to 1000oF (540oC) then air cool.QuenchingAISI 52100 alloy bearing steel could be hardened by quenching in water from 801-829 degree or quench in oil from 816-842 degree.TemperingTemper to desired hardness as indicated by tempering curves after water or oil quench.Product specificationTolerancesPipe typesPipe sizes(mm)TolerancesHot rolledOD<50±0.50mmOD≥50±1%WT<4±12.5%WT 4~20+15%, -12.5%WT>20±12.5%Cold drawnOD 6~10±0.20mmOD 10~30±0.40mmOD 30~50±0.45OD>50±1%WT≤1±0.15mmWT 1~3+15%, -10%WT >3+12.5%, -10%product application52100 Alloy Seamless Tube & Pipe For Bearing1.
