316/316L vs 304/304L
Hom 316 / 316L / 316H yog austenitic stainless hlau npaj siv rau hauv cov ntawv thov uas xav tau lub zog siab, tawv thiab ua haujlwm tau zoo, nrog rau kev txhim kho corrosion.Muab piv rau 304 stainless hlau, 316 muaj feem pua ntawm molybdenum ntau dua (Mo 2% -3%) thiab npib tsib xee (Ni 10% mus rau 14%), Molybdenum muaj kev tiv thaiv zoo tag nrho, tshwj xeeb tshaj yog rau pitting thiab crevice corrosion hauv chloride ib puag ncig.316 muaj cov khoom zoo heev thiab cov khoom siv hluav taws xob ntawm qhov kub qis, haum rau txias dov, nruam zeb phaj thiab phaj millplate daim ntawv, thickness ntau txog 60 nti.

316L / TP316L Stainless hlau yeeb nkab
Qib 316L yog hais txog S31603 UNS deination 1.4404, nws muaj kev tiv thaiv corrosion zoo dua li TP316 vim tias cov ntsiab lus carbon tsawg.316L siab tshaj carbon cov ntsiab lus 0.03% uas 316 siab tshaj 0.08%, siab dua cov pa roj carbon ntau yuav ua rau intergranular corrosion.Yog li, 316L yog qhov tsim nyog rau cov ntawv thov uas yuav tsum tau zam cov nag lossis daus.Qhov no stainless hlau yog dav siv rau vuam cov khoom, nws cov ntsiab lus tshwj xeeb cov pa roj carbon monoxide ua ke ua kom muaj kev tiv thaiv siab tshaj plaws rau kev xeb, tshwj xeeb tshaj yog siv rau cov khoom hnyav.
316L raug suav hais tias tiv taus oxidation ntau dua li hom 316, tshwj xeeb tshaj yog nyob rau hauv qhov chaw sov marine.Ntxiv dua thiab, nws cov ntsiab lus qis carbon tiv thaiv nws los ntawm cov nag lossis daus.Cov hlau kuj nthuav tawm qhov tsis kam ntawm qhov kub tsis tshua muaj, txawm tias mus rau qib cryogenic.Nyob rau hauv cov nqe lus ntawm tshav kub tsis kam, 316L nthuav tawm zoo dua creep tsis kam, tawg kev nyuaj siab tsis kam thiab tag nrho lub zog tshaj lwm yam stainless hlau qib.
Ntau yam kev ua haujlwm zoo ib yam uas siv tau rau Hom 316 kuj tseem tuaj yeem siv rau 316L, suav nrog kev sib txuas thiab kev ua haujlwm txias.Tsis tas li ntawd, 316 tsis tas yuav tsum tau ua haujlwm tom qab annealing los ua kom nws qhov kev tiv thaiv corrosion, tab sis annealing yuav siv tau rau qee kis.
316H / TP316H Stainless hlau
Qib 316H yog hais txog S31609, cov ntsiab lus carbon 0.04% rau 0.10%, nws muab kub ua haujlwm siab dua 316L.
316 Ti/TP 316 Ti
Stainless hlau 316Ti yog lub npe hu ua qib ruaj khov ntawm 316 hom thiab tseem yog ib qho ntawm ob 316 stainless hlau pom zoo rau kev siv kub dua.Qib no muaj me me (feem ntau tsuas yog 0.5%) ntawm titanium.Thaum nws tseem sib koom ntau yam khoom ntawm lwm qib 316, qhov sib ntxiv ntawm titanium tiv thaiv 316Ti los ntawm nag lossis daus ntawm qhov kub thiab txias, txawm tias muaj kev cuam tshuam ntev.
Molybdenum kuj tseem ntxiv rau qhov muaj pes tsawg leeg ntawm 316Ti.Zoo li lwm qib 316, molybdenum muab kev tiv thaiv zoo tiv thaiv corrosion, tshuaj chloride pitting thiab lub zog thaum muab tso rau hauv qhov kub thiab txias.Txawm li cas los xij, nws qhov kub thiab txias kuj tseem sib xyaw los ntawm nws cov ntsiab lus titanium, uas ua rau 316Ti tiv thaiv los nag ntawm qhov kub thiab txias.Tsis tas li ntawd, cov hlau tiv taus cov kua qaub xws li sulfuric acid, hydrochloric acid, thiab acid sulfates.
316Ti feem ntau yog siv rau hauv cov khoom siv hluav taws xob, cov khoom siv hauv cov ntawv zeb thiab cov khoom siv hauv tsev hauv marine ib puag ncig.
TP316LN/316N
316N: Nitrogen (N) yog ntxiv rau 316 stainless hlau kom lub zog tsis txo cov yas, kom cov thickness ntawm cov khoom raug txo.Rau siab zog qhov chaw nrog zoo corrosion kuj.
316LN zoo li 316L nrog N ntxiv, muaj kev tiv thaiv corrosion zoo dua li 316N.
TP316 / 316L / 316H / 316Ti Stainless Hlau Yeeb Nkab Daim Ntawv Thov
TP316/316L seamless yeeb nkab yog siv rau cov kua los yog roj siab hloov mus rau hauv dej kho, dej khib nyiab, petrochemical, tshuaj, tshuaj thiab lwm yam lag luam.Thiab cov ntawv thov kev tsim muaj xws li tes tuav, ncej thiab cov yeeb nkab txhawb nqa rau cov dej ntsev thiab qhov chaw corrosive.Piv nrog TP304 stainless hlau, TP316 stainless hlau yeeb nkab muaj qis weldability, yog li nws tsis yog siv ntau npaum li cov yeeb nkab welded tshwj tsis yog nws cov corrosion kuj zoo tshaj weldability.
