304 stainless hlau seamless yeeb nkab vim yog thermal embrittlement ntawm 304 stainless hlau seamless yeeb nkab ntawm cov seams vim sib txawv coefficients ntawm expansion qhov muag thaum rhuab tsim ib tug ntau ntawm tshav kub kev nyuaj siab, tshwj xeeb tshaj yog thaum lub sij hawm ceev kub hloov vim thermal shock zoo li. steel quenching tawg yuav tsim tib yam tshwm sim.

Ntawm qhov kub thiab txias hloov kaum ob lossis ntau pua zaus rov ua cua sov yuav ua rau thermal qaug zog tawg.Tab sis raws li ib tug kub thiab qaug zog, uas yog tsim nyob rau hauv high kub vim lub load sab nraud variations tshwm sim, thaum lub qub yog raws li ib tug thermal hloov vim lub thermal stresses tshwm sim los ntawm embrittlement.

304 stainless hlau seamless yeeb nkab kev nyuaj siab corrosion engineering kev huam yuaj, tom qab macroscopic kev ntsuam xyuas, cov ntsiab lus, tsuas yog lub zos yeeb nkab seem kev nyuaj siab corrosion kev puas tsuaj ntawm cov khoom thiab cov khoom los ntawm corrosion (kev nyuaj siab corrosion cracking thiab pitting, crevice corrosion), thiab tsis muaj qhov tseem ceeb ntawm corrosion.Txawm tias thaum raug kev nyuaj siab heev corrosion kev puas tsuaj ntawm cov cuab yeej yog tsis muaj kev zam.Hauv qee qhov kev tshaj tawm, qee zaum ob qho tib si kev nyuaj siab corrosion (los yog nrog rau cov pitting hnyav), muaj kev xeb loj heev.
