Taw qhia
Stainless hlau yog cov hlau alloy siab.Cov hlau no muaj nyob rau hauv plaub pawg uas suav nrog martensitic, austenitic, ferritic thiab nag lossis daus-hardened steels.Cov pab pawg no yog tsim los ntawm cov qauv crystalline ntawm stainless hlau.
Stainless hlau muaj cov chromium ntau dua nyob rau hauv kev sib piv nrog rau lwm cov hlau thiab yog li muaj corrosion kuj zoo.Feem ntau ntawm cov hlau tsis muaj steel muaj li ntawm 10% ntawm chromium.
Qib 2205 stainless hlau yog ib tug duplex stainless hlau uas nws tsim enables combining txhim kho tsis kam mus pitting, siab zog, kev nyuaj siab corrosion, crevice corrosion thiab cracking.Qib 2205 stainless hlau resists sulfide kev nyuaj siab corrosion thiab chloride ib puag ncig.
