Kev Piav Qhia Luv:
Din 1.4034 SS 430 Tiaj Tus Tuav, SS UNS S42000 Tiaj Tus Tuav, Stainless Hlau 420 Tiaj Tus Tuav, 420 Stainless Hlau Txias Kos Cov Tuav Khoom Siv Hauv Suav Teb.
Qib 420 stainless hlau yog cov hlau uas muaj cov pa roj carbon ntau nrog cov ntsiab lus chromium tsawg kawg nkaus ntawm 12%. Ib yam li lwm cov hlau tsis xeb, qib 420 kuj tseem tuaj yeem ua kom tawv los ntawm kev kho cua sov. Nws muaj cov khoom zoo hauv nws lub xeev annealed thiab cov khoom tiv thaiv corrosion zoo heev thaum cov hlau raug polished, nto grounded lossis hardened. Qib no muaj qhov nyuaj tshaj plaws - 50HRC - ntawm txhua qib stainless hlau nrog 12% chromium.
