Cov chromium tam sim no nyob rau hauv cov hlau muab nws qhov zoo ntawm lub zog zoo nyob rau hauv daim ntawv thov ntawm tshav kub kub thiab zoo heev corrosion rau kuj. Cov khoom zoo yog muaj vim muaj lwm yam khoom ntawm cov tshuaj. Cov ntsiab lus zoo li molybdenum, phosphorus, manganese, niobium, thiab carbon yog muaj nyob rau hauv stainless hlau uas ua rau muaj kev ncaj ncees cov yam ntxwv thiab cov khoom. Ob peb qib muaj nyob rau hauv kev ua lag luam ntawm cov hlau tab sis qib uas tau siv dav los ua SS coils yog 420.

Qib piav qhia:
Nws yog martensitic stainless hlau uas muab corrosion kuj nrog ntxiv zog thiab hardness. Nws tab tom nrhiav cov khoom sib nqus hauv cov txheej txheem annealed thiab hardened tej yam kev mob. Txawm li cas los xij, ntau dua corrosion kuj yog attained nyob rau hauv tag nrho hardened thiab kev nyuaj siab relieved mob. Nws yog qhov zoo tshaj plaws los siv nyob rau hauv qhov kub siab tshaj 800 deg f vim yog softening sai thiab poob ntawm corrosion. Ss coils yog siv nyob rau hauv lub hardened thiab kev nyuaj siab relieved mob kom muaj zog corrosion kuj. Thaum nws yog annealed nws muaj kev ua haujlwm tsis zoo corrosion thiab ntawm qhov ntau, nws tsis siv. Cov coils no yog annealed rau siab tshaj plaws softness. Tsis tas li ntawd, nws tuaj yeem raug kos thiab tsim.
