Dab tsi yog qhov txawv ntawm sus 316 thiab sus 316L?
Tso lus
SUS316 yog dab tsi?
SUS316 yog qib ntawm austenitic stainless hlau, tseem hu ua AISI 316, uas yog superior rau SUS304 vim qhov sib ntxiv ntawm 2-3% molybdenum. Qhov no ua rau nws tiv taus corrosion los ntawm cov tshuaj chlorides thiab lwm yam tshuaj, ua rau nws zoo tagnrho rau kev siv dej hiav txwv, kev kho mob, thiab kev siv tshuaj. Qhov kev xaiv "SUS" yog los ntawm Japanese Industrial Standards (JIS).
Lub ntsiab lus ntawm SUS 316L yog dab tsi?
SUS 316L txhais tau tias "Steel Use Stainless" qib 316L, raws li Japanese Industrial Standards (JIS) tsim. Nws yog hais txog ib hom austenitic stainless hlau uas muaj cov pa roj carbon tsawg, uas yog resistant rau corrosion thiab zoo tagnrho rau vuam.
Dab tsi yog qhov txawv ntawm sus 316 thiab sus 316L?
Qhov sib txawv tseem ceeb ntawm SUS 316 thiab SUS 316L nyob hauv lawv cov ntsiab lus carbon; 316L muaj cov ntsiab lus qis dua (0.03%) dua li 316 (0.08%). Cov ntsiab lus qis dua ntawm 316L ua rau nws tsis tshua muaj carbide nag lossis daus thaum lub sijhawm vuam, yog li tshem tawm qhov xav tau tom qab vuam annealing los txhim kho corrosion kuj, ua rau nws zoo tagnrho rau vuam daim ntaub ntawv . 316 muaj me ntsis yield zog thiab tensile zog tshaj 316L.

SUS 316 vs SUS 316L: Corrosion Resistance
Muab piv rau Corrosion Resistance ntawm 316 Stainless SteelSUS 316L muaj superior corrosion kuj piv rau SUS 316, tshwj xeeb tshaj yog nyob rau hauv welded daim ntaub ntawv, vim nws cov ntsiab lus carbon tsawg. Qhov no txo cov pa roj carbon monoxide nyob rau hauv 316L tiv thaiv kev tsim ntawm corrosive chromium carbide precipitates nyob rau hauv lub tshav kub-cuam tshuam cheeb tsam thaum vuam, uas yuav ua rau intergranular corrosion nyob rau hauv txheem SUS 316. Ob alloys yog heev corrosion-resistant, tab sis cov qib "L" yog qhov zoo dua xaiv rau daim ntaub ntawv uas muaj welding.
SUS 316 vs SUS 316L: Weldability
SUS 316L yog qhov zoo tshaj rau SUS 316 rau vuam vim nws cov ntsiab lus qis qis tiv thaiv cov vuam lwj (sensitization thiab intergranular corrosion) yam tsis tas yuav tsum tau kho cua sov tom qab vuam. Thaum ob qib tuaj yeem welded, 316 yog qhov cuam tshuam rau daim ntawv no ntawm corrosion thiab feem ntau yuav tsum tau annealing los kho corrosion kuj nyob rau hauv welded cheeb tsam. Rau cov haujlwm uas xav tau kev vuam dav, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig corrosive, 316L yog qhov kev xaiv zoo dua.
SUS 316 vs SUS 316L: Formability
Ob leeg SUS 316 thiab SUS 316L muaj cov qauv zoo heev, txhais tau tias lawv yog ob qho tib si khoov tau yooj yim, ncab, thiab zoo li tsis tawg. Qhov sib txawv tseem ceeb yog tias 316L muaj qhov zoo tshaj plaws weldability vim nws cov ntsiab lus qis dua, uas ua rau nws qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas muaj qhov hnyav-gauge vuam thiab qhov twg tom qab vuam corrosion kuj tseem ceeb heev.
Yog tias koj tab tom nrhiav corrosion-resistant stainless hlau rau kev lag luam lossis marine ib puag ncig, xaiv ntawm SUS 316 thiab SUS 316L yog qhov tseem ceeb.
