Khoom Taw Qhia

ASTM A240 Hom 420 muaj cov pa roj carbon ntau ntxiv los txhim kho cov khoom siv kho tshuab. Cov ntawv thov xws li cov cuab yeej phais. SS 420 Phaj yog lub hardenable, martensitic stainless hlau uas yog kev hloov kho ntawm SS 410 Phaj.

Zoo ib yam li SS 410 Phaj, nws muaj qhov tsawg kawg nkaus ntawm 12% chromium, txaus txaus los muab cov khoom tiv thaiv corrosion. Muaj nyob rau hauv ntau qhov sib txawv ntawm cov ntsiab lus carbon 420 stainless hlau phaj yog tsim rau kev kho cua sov. Stainless Hlau 420 Phaj muaj 13% chromium cov ntsiab lus uas muab cov lus qhia ib theem ntawm corrosion kuj zog. Cov qhab nia British muaj nyob rau hauv 420S29, 420S37, 420S45 Phaj.

ASTM A240 Hom 420 Daim Ntawv Thov:

Alloy 420 yog siv rau ntau yam kev siv uas zoo corrosion thiab zoo hardness yog tsim nyog. Nws tsis haum qhov twg qhov kub siab tshaj 800 ° F (427 ° C) vim ceev hardening thiab poob ntawm corrosion kuj.
