321 Cov Hlau Stainless Seamless Yeeb Nkab
Kev Piav Qhia Luv:
ASTM TP321 Seamless Yeeb Nkab:
321 stainless hlau seamless yeeb nkab yog ib yam khoom siv ua tau zoo heev uas siv dav hauv qhov chaw kub siab. 321 stainless hlau yog ua los ntawm 18Cr-8Ni sib xyaw nrog ntxiv titanium los txhim kho nws txoj kev tiv thaiv rau intergranular corrosion. 321 stainless hlau seamless yeeb nkab ua tau zoo heev hauv qhov chaw kub siab thiab tuaj yeem siv tas li hauv qhov kub ntawm 800-1500 ° F (427-816 ° C), nrog rau qhov kub siab tshaj plaws ntawm 1700 ° F (927 ° C). Vim yog ntxiv titanium, 321 stainless hlau muaj kev tiv thaiv zoo rau intergranular corrosion, ua rau nws haum rau qhov chaw uas intergranular corrosion yuav tshwm sim hauv qhov kub siab. 321 stainless hlau muaj lub zog siab thiab lub zog tensile, nrog rau kev ua tau zoo thiab toughness. 321 stainless hlau tuaj yeem welded siv cov txheej txheem vuam ib txwm muaj, tab sis post-weld annealing tej zaum yuav tsim nyog los rov qab nws txoj kev tiv thaiv corrosion.
