Cov hlau tsis xeb 309thiab 310 yog ob qho tib si austenitic stainless hlau alloys uas tiv taus cua sov, tab sis lawv muaj qee qhov sib txawv hauv lawv cov khoom sib xyaw thiab cov ntawv thov.309: Muaj kev tiv taus kub zoo thiab tuaj yeem tswj tau qhov kub txog li 1000 ° C (1832 ° F). Nws feem ntau siv rau hauv qhov cub tawg, cov khoom hloov pauv cua sov, thiab cov chaw kub siab.310: Muaj kev tiv taus kub zoo dua thiab tuaj yeem tiv taus kub txog li 1150 ° C (2102 ° F). Nws tsim nyog rau cov ntawv thov hauv cov chaw kub heev, xws li cov cub tawg, cov kilns, thiab cov raj radiant.

Hauv kev xaus, qhov sib txawv tseem ceeb ntawm cov hlau tsis xeb 309 thiab 310 yog lawv cov khoom sib xyaw thiab kev tiv taus kub. 310 muaj cov chromium ntau dua me ntsis thiab cov ntsiab lus nickel qis dua, ua rau nws zoo dua rau cov ntawv thov kub dua li 309. Koj qhov kev xaiv ntawm ob qho yuav nyob ntawm qhov xav tau tshwj xeeb ntawm koj daim ntawv thov, suav nrog qhov kub, kev tiv taus corrosion, thiab cov khoom siv kho tshuab.
