18CrNiMo7-6 Alloy Steel Bar
Cov Cuab Yeej Tshwj Xeeb J / (kg.K): 460
Hluav taws xob Resistivity Ohm.mm2 /m: 0.18
Hluav taws xob conductivity Siemens.m/mm2: 5.55
DIN1.6587/18CrNiMo7-6 yog cov pa roj carbon tsawg, cov ntaub ntawv hardening (carburizing) steel uas muaj 1.8 feem pua chromium - npib tsib xee - molybdenum ua cov tshuaj ntxiv dag zog raws li EN 10084. Cov yam ntxwv los ntawm cov tub ntxhais muaj zog thiab tawv tawv hauv nruab nrab mus rau qhov loj. nrog cov ntaub ntawv hardness txog Rc62 thaum carburized, hardened thiab tempered, thiab nws kuj yog siv nyob rau hauv cheeb tsam ntawm hnyav thiab siab strained iav qhov chaw nrog siab xav tau ntawm toughness ntawm core tensile ntawm 1050–1350N / mm2.DIN1.6587/18CrNiMo{14 }} yog tib yam li 17CrNiMo6 steel, feem ntau muab nyob rau hauv lub annealed mob nrog lub siab tshaj plaws brinell hardness ntawm 229
