1. 304 stainless hlau yog austenitic stainless hlau, ib yam khoom nyob rau hauv stainless hlau (SUS304 stainless hlau hu ua nyob rau hauv Nyiv, 304 stainless hlau hu ua nyob rau hauv lub tebchaws United States, thiab hu ua 0Cr18Ni9 nyob rau hauv kuv lub teb chaws), muaj 19 feem pua chromium, suav nrog Nickel 9 feem pua, qhov ceev 7.93 g / cm3.
2. 316 stainless hlau yog Omartensitic stainless hlau. Rau lub hauv paus ntawm 304 stainless hlau, molybdenum ntxiv. Qhov nruab nrab nickel ntsiab lus ntawm 316 stainless hlau yog 12 feem pua, uas yog siab tshaj qhov nruab nrab nickel ntsiab lus ntawm 304, uas yog 9 feem pua, yog li tus nqi yuav kim dua 304 stainless hlau.
3. 403 yog ferritic stainless hlau, thiab 403 16Cr yog ib tug neeg sawv cev qib steel ntawm ferritic steel, nrog zoo thermal expansion tus nqi, zoo heev formability thiab oxidation kuj. 304 stainless hlau muaj txog 8 feem pua nickel thiab 403 tsis muaj npib tsib xee. 304 muaj zoo corrosion kuj thiab toughness tshaj 403, uas yog ib tug hardenable stainless hlau nrog siab hardness tom qab quenching.
