309 Stainless Hlau Yeeb Nkab Corrosion Resistance thiab Kub Resistance
AISI 309 stainless hlau yeeb nkab muaj cov cua kub zoo thiab tuaj yeem tiv taus qhov kub txog li 1000 degree yam tsis muaj oxidation, tab sis tuaj yeem tsim σ theem ntawm qhov kub siab tshaj 900 degree, uas yuav txo tau cov corrosion kuj thiab txhua yam khoom ntawm cov khoom. Nws cov corrosion kuj yog qhov zoo, nrog rau nruab nrab tsis kam rau sulfur-muaj gases thiab zoo heev tsis kam mus rau nitrogen-muaj gases.
