Stainless hlau yog txhais nyob rau hauv GB / T20, 878-2007 raws li ib tug steel nrog stainless hlau thiab corrosion kuj raws li nws cov yam ntxwv tseem ceeb, chromium cov ntsiab lus ntawm tsawg kawg yog 10.5 feem pua thiab cov ntsiab lus carbon ntawm ntau tshaj 1.2 feem pua.
Stainless hlau yog lub ntsiab lus ntawm stainless thiab acid resistant steel. Cov hlau uas tiv taus tsis muaj zog corrosive media xws li huab cua, chav dej thiab dej los yog muaj cov khoom tsis zoo yog hu ua stainless hlau; Cov hlau uas tiv taus tshuaj corrosion nruab nrab yog hu ua acid resistant steel.
Vim qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg, lawv cov corrosion kuj sib txawv. Ordinary stainless hlau feem ntau tsis resistant rau tshuaj nruab nrab corrosion, thaum acid resistant steel feem ntau stainless. Lub sij hawm "stainless steel" tsis tsuas yog hais txog ib hom stainless hlau, tab sis kuj hais txog ntau tshaj 100 hom kev lag luam stainless hlau. Txhua hom stainless hlau tsim muaj kev ua tau zoo hauv nws daim ntawv thov tshwj xeeb.
Feem ntau hais lus, lub hardness ntawm stainless hlau yog siab dua li ntawm aluminium alloy, thiab tus nqi ntawm stainless hlau yog siab dua li ntawm aluminium alloy.
