Tsis tas li ntawd, nws muaj cov ntsiab lus xws li silicon (Si) Tsawg dua lossis sib npaug li 1.0%, manganese (Mn) Tsawg dua lossis sib npaug li 2.0%, phosphorus (P) Tsawg dua lossis sib npaug li 0.04% (qee qhov chaw hais tsis ntau tshaj 0.045%), thiab sulfur (S) Tsawg dua lossis sib npaug li 0.030%.
Mechanical Properties: A312 TP316L stainless hlau seamless yeeb nkab txais ib qho qis - cov ntsiab lus carbon cov ntsiab lus tsim lub tswv yim, txo cov nag lossis daus ntawm chromium carbide thaum vuam, yog li ua kom tsis txhob muaj kev hem thawj ntawm intergranular corrosion thiab txhim kho cov khoom siv corrosion kuj. Tshwj xeeb tshaj yog tsim nyog yog nws zoo heev corrosion kuj nyob rau hauv chloride media thiab siab -kub ib puag ncig. Tsis tas li ntawd, A312 TP316L kuj nthuav tawm cov khoom siv zoo tshaj plaws thiab kev ua haujlwm.
Vuam Kev Ua Tau Zoo: Cov txheej txheem tsim khoom ntawm A312 TP316L stainless hlau seamless yeeb nkab suav nrog cov txheej txheem tseem ceeb, suav nrog kev npaj cov khoom siv raw, melting thiab casting, kub dov los yog txias dov, koom nrog (vuam), kev kho cua sov, tsis yog - kuaj kev puas tsuaj, thiab kev kho deg. Cov txheej txheem vuam siv cov txheej txheem vuam zoo tshaj plaws, xws li TIG welding (tungsten inert gas welding) lossis MIG welding (hlau inert gas welding), kom ntseeg tau tias cov welds ua tau raws li cov qauv zoo. Cov kauj ruam kho cua sov yog txhawm rau tshem tawm cov kev ntxhov siab sab hauv uas tau tsim thaum lub sij hawm vuam, yog li txhim kho tag nrho cov kev ua tau zoo ntawm cov kav dej.

Kev sib piv ntawm ASTM A312 TP316L Stainless hlau nrog rau lwm cov ntaub ntawv
Piv rau TP304: TP316L, vim nws cov ntsiab lus molybdenum, muaj kev tiv thaiv zoo tshaj rau pitting corrosion, ua rau nws xaiv ntau "advanced".
Piv rau TP321: Ob qhov chaw nyob intergranular corrosion, tab sis nyob rau hauv ntau txoj kev. TP316L ua tiav qhov no los ntawm ultra- cov ntsiab lus carbon tsawg, thaum TP321 ruaj khov nws cov ntsiab lus carbon los ntawm kev ntxiv titanium. TP321 tseem ceeb tshaj - qhov kub thiab txias, thaum TP316L tsom ntau rau kev tiv thaiv chloride ion corrosion ntawm chav tsev kub / qis kub.
"L" Hom vs. Standard Hom: Feem ntau, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov uas yuav tsum tau vuam, TP316L muaj kev nyab xeeb thiab txhim khu kev qha ntau tshaj li tus qauv TP316, tshwj tsis yog tias muaj kev kub ntxhov siab heev - qhov yuav tsum tau muaj zog.
