321/321H Stainless Hlau Phaj - Siab - Kub & Oxidation Resistance

General Properties

Alloy 321 (UNS S32100) yog titanium stabilized austenitic stainless hlau phaj nrog zoo corrosion kuj. Nws muaj kev tiv thaiv zoo heev rau intergranular corrosion tom qab raug kub hauv chromium carbide nag lossis daus ntawm 800 - 1500℃F (427 - 816 degree). Lub alloy tiv taus oxidation mus rau 1500℃F (816 degree) thiab muaj ntau dua creep thiab kev nyuaj siab rupture zog dua alloys 304 thiab 304L. Nws kuj muaj qhov zoo ntawm qhov kub thiab txias toughness.
