420 stainless hlau tiaj li bar
Cov lus piav qhia luv luv:
DIN 1.4034 SS 430 pob zeb ncaj, SS Unu S42000 lub pob zeb ncaj, Hlau Stainless 420 tiaj tus hlau tawg cov khoom lag luam txuas rau Suav teb.
Qeb 420 stainless hlau yog ib tug high-carbon hlau nrog qhov tsawg kawg nkaus cov ntsiab lus chromium tsawg kawg ntawm 12%. Zoo li lwm yam stainless hlau, qib 420 kuj tseem tuaj yeem ua kom tiav los ntawm kev kho cua sov. Nws muaj cov qauv ducity nyob rau hauv nws annealed lub xeev thiab zoo heev corrosion protigerance thaum cov hlau yog polished, saum npoo av lossis tawv tawv. Cov qib kawm no muaj lub siab tshaj plaws - 50hrc - ntawm txhua tus stainless hlau qib nrog 12% chromium.
