| Hluav taws xob Resistivity | 20 ° C | 0,74m ;ua | 0.74 Ω |
Qhov ntom ntawm 420J2 stainless hlau qhia nws qhov hnyav, uas yog qhov kev txiav txim siab hauv cov ntawv thov uas qhov hnyav hnyav yog qhov tseem ceeb. Lub melting point qhia tias nws haum rau siab - daim ntawv thov kub, thaum thermal conductivity thiab tshwj xeeb kub muaj peev xwm yog ib qho tseem ceeb rau cov kev siv uas muaj xws li thermal tswj.
