Gear Steel Bar factory 20CrMnTi is a carburized steel with good performance and high hardenability. After carburizing and quenching, it has a hard and wear-resistant surface and a tough center, high low-temperature impact toughness, medium weldability, and good machinability after normalizing. It is a substitute steel of 18CrMnTi, which is widely used as carburized parts. In the automobile and tractor industries, it is used as an important carburized part with a section of less than 30mm, which can withstand high speed, medium or heavy load, impact and friction, such as gear, shaft, gear ring, gear shaft, main shaft of sliding bearing, crosshead, claw clutch, worm, etc. Chemical聽Composition聽and聽Mechanical聽Properties(In聽Quenched聽&聽Tempered聽State) Material20CrMnTi Chemical聽CompositionMechanical聽Properties(In聽Quenched聽&聽Tempered聽State) C0.17-0.23Tensile聽strength(MPA)聽鈮?080 Si0.17-0.37Yield聽strength聽(MPA)鈮?50 Mn0.80-1.10Elongation(未5/%)鈮?0% Cr1.00-1.30Reduction聽in聽Area聽(蠄/%)鈮?5% Ti0.04-0.10Impact聽聽(J)鈮?5 P鈮?.030聽聽 Hardness聽聽聽聽鈮?17HB聽聽 S鈮?.030 V------- 聽 Similar聽steel聽grade聽&聽Equivalent聽steel聽materials USAJapaneseGemanyBritishFranceInternationalChinese ASTM&AISI&SAEJISEN聽DINEN聽BSEN聽NFISOGB ----SCM421---------------20CrMnTi 聽 Product聽Sales聽Information SizeDiameter:10mm-1000mm Length:5000mm-6000mm Origin聽place聽Made聽In聽China Delivery聽ConditionHot聽rolled,cold聽drawn,forged Surface聽requireBlack,grinding,bright,polish Heat聽treatmentQuenched,Tempered,annealed Packingseaworthy聽packing聽,wooden聽case聽,carton,woven聽bag聽or聽at聽client's聽requires Delivery聽timeIn聽10-50聽days Trade聽TermEXW,FOB,CIF PaymentsT/T聽or聽L/C聽at聽sight PortChina聽main聽Port,such聽as聽shanghai,Dalian,Shenzhen聽port.
