Ntaub
khaub thuas ua haujlwm: Tsis pom zoo, tsuas yog rau kev tiv thaiv me. Kev tiv thaiv hnyav tuaj yeem ua rau tawg.
Kub Ua Haujlwm: Ua tom qab cov cua kub sib txawv rau 2100-2250℃f (1149-1232 degree). Kub ua haujlwm qis dua 1700℃f (927 degree) tej zaum yuav ua rau tawg.
Hwj txwv
Qeb 420 stainless hlau muaj cov tsis zoo weldability. Nws yog qhov siv tau rau preheat rau 150-320℃ua raws los ntawm cua sov rau 610-760 degree. Qeb 420 coated electrodes tuaj yeem siv rau cov pob qij txha siab, uas tuaj yeem ua kom muaj kev cia siab thiab npau taws tom qab vuam. Yog tias cov seem yuav tsum tau siv ncaj qha rau hauv lub xeev welded, cov pob qij txha tuaj yeem tsim nrog qib 309 vuam hlau lossis hluav taws xob.
Dab tsi yog qhov sib txawv ntawm 1.4021 thiab 1.4028?
Qhov sib txawv tseem ceeb yog1.4028Muaj cov ntsiab lus carbon ntau dua (0.26-0.35%) piv rau1.4021(0.16-0.25%), ua 1.4028 yooj yim dua ntawm cov zog thiab qib nyuaj. Yog li ntawd, 1.4028 muaj ntau dua hardness muaj peev xwm, thaum 1.4021 muaj me ntsis zoo corrosion tsis kam thiab 1.4028 me ntsis qis zog.
