302 yog ib qho kev hloov pauv ntawm 18 feem pua chromium / 8 feem pua nickel austenitic alloy, uas yog cov paub zoo tshaj plaws thiab feem ntau siv hauv tsev neeg stainless hlau. Alloy 302 yog cov pa roj carbon ntau dua me ntsis ntawm 304, feem ntau pom nyob rau hauv daim ntawv sawb thiab hlau. Nws yog ib qho tawv, qib ductile uas qhia tau hais tias muaj kev sib piv corrosion kuj, tsis yog-sib nqus, thiab tsis hardenable los ntawm kev kho cua sov. Alloy 302 feem ntau yog siv rau hauv nws cov mob annealed thiab muaj qhov yooj yim ntawm fabrication thiab formability.
| Khoom | 302 |
| Yield zog, min. (ksi) | 30 |
| Tensile zog, min. (ksi) | 75 |
| Elongation, min. (%) | 40 |
| Hardness, max. (Rb) | 92 |
Tsis tas li ntawd, ntau yam kev siv feem ntau suav nrog cov tshuaj hauv tsev thiab kev lag luam. Lub 18 mus rau 19 feem pua ntawm chromium uas cov alloys muaj muab kev tiv thaiv rau oxidizing ib puag ncig xws li dilute nitric acid. Cov alloys no kuj tiv taus cov organic acids xws li acetic, thiab txo cov acids xws li phosphoric. Lub 9 mus rau 11 feem pua ntawm cov npib tsib xee uas muaj los ntawm cov 18-8 alloys pab muab kev tiv thaiv rau ib puag ncig txo qis. Qhov ntau txo qhov chaw xws li boiling dilute hydrochloric thiab sulfuric acids tau pom tias yuav nruj heev rau cov ntaub ntawv no. Boiling 50 feem pua ntawm caustic yog ib yam nkaus thiab txhoj puab heev.
