Tso lus
Thaum xaiv ntawm 316, 316L, lossis 316H stainless hlau, cov neeg yuav khoom feem ntau tawm tsam los txiav txim siab qib twg zoo tshaj plaws rau lawv daim ntawv thov raws li kev tiv thaiv corrosion, weldability, thiab siab - qhov kub thiab txias. Txawm hais tias tag nrho peb yog molybdenum- muaj cov austenitic stainless hlau, lawv cov ntsiab lus carbon sib txawv, cuam tshuam ncaj qha rau lawv cov kev ua tau zoo hauv ntau yam kev siv.
Dab tsi yog 316, 316L, thiab 316H Stainless Hlau?
Dab tsi yog316 Stainless hlau?
316 stainless hlau, feem ntau hu ua marine stainless hlau, yog qib siab -qib austenitic stainless hlau uas feem ntau muaj 16-18% chromium, 10-14% npib tsib xee, thiab 2-3% molybdenum, nrog rau me me ntawm carbon, manganese, thiab silicon . 316 nws lub zog zoo dua 0. kub txog 870℃(1600℃F), thiab nws lub zog tuav tau zoo dua nyob rau hauv 800-304℃ntau piv rau 500.
AISI 316L Stainless hlau yog dab tsi?
316L yog qib stainless hlau, koom nrog American ASTM tus qauv. Nws cov qib sib raug zoo hauv Suav GB tus qauv system yog 022Cr17Ni12Mo2, thiab nws cov lej sib koom ua ke yog S31603. Nws tsis yog- sib nqus thiab tsis tuaj yeem ntxiv dag zog los ntawm kev kho cua sov; nws lub zog tsuas tuaj yeem txhim kho los ntawm kev ua haujlwm txias. Nws muaj zoo plasticity thiab toughness ntawm ob chav tsev thiab tsis kub, yog ib qho yooj yim rau tsim, thiab muaj zoo weldability. Nws cov khoom muaj xws li daim hlau, tuav, kav, strips, xov hlau, thiab forgings.
Dab tsi yog316H Stainless hlau?
316H stainless hlau yog siab - carbon austenitic stainless hlau nrog siab dua - kub lub zog. Nws yog qhov sib txawv ntawm tus qauv 316 stainless hlau, thiab nws cov ntsiab lus carbon ntau dua (0.04% - 0.10%) ua rau nws tsim nyog rau kev siv xws li kev tsim hluav taws xob, kev lag luam tshuaj, thiab kev lag luam petrochemical uas xav tau lub zog zoo heev ntawm qhov kub thiab txias.

Corrosion Resistance
Hom 316 thiab 316L Stainless Steels tso saib zoo dua corrosion kuj tshaj hom 304. Lawv muab cov pitting zoo heev thiab zoo heev tiv thaiv rau feem ntau cov tshuaj koom nrog hauv textile, ntawv thiab yees duab industries.
Vim li cas 316L stainless hlau zoo dua rau vuam dua li 316 stainless hlau?
316L stainless hlau yog qhov zoo dua rau kev vuam dua li 316 stainless hlau vim tias nws cov ntsiab lus qis dua (ntau tshaj 0.03%) txo qhov kev pheej hmoo ntawm carbide nag lossis daus (tseem hu ua sensitization) hauv tshav kub - cuam tshuam cheeb tsam. Qhov no tiv thaiv weld corrosion, uas txo cov corrosion kuj ntawm weld grain ciam teb. Yog li ntawd, 316L tsis xav tau tom qab-welding tshav kub kev kho mob los kho nws cov corrosion kuj, ua rau nws nyiam cov khoom siv vuam siv.
Puas yog 316 lossis 316H stainless hlau sib nqus?
Tsis yog, tsis yog 316 lossis 316H stainless hlau tsis yog hlau nplaum hauv nws lub xeev annealed, tab sis lawv tuaj yeem ua hlau nplaum tom qab qee cov txheej txheem. Ob leeg yog austenitic stainless hlau uas tsis yog- sib nqus, tab sis lawv tuaj yeem tsim qhov tsis muaj zog sib nqus yog tias txias- ua haujlwm (xws li khoov lossis hammered) lossis thaum welded, raws li cov txheej txheem no tuaj yeem ua rau lub sijhawm hloov pauv.
Qhov txawv ntawm 316L thiab 316H yog dab tsi?
Qhov sib txawv tseem ceeb nyob hauv cov ntsiab lus carbon . 316L muaj cov ntsiab lus qis dua (qhov siab tshaj<0.03%), while 316H has a higher carbon content (maximum 0.04-0.10%). Due to this difference in carbon content, 316L is more suitable for welding applications because it has a lower rate of intergranular corrosion after welding. In contrast, the higher carbon content of 316H gives it higher strength at high temperatures, making it more suitable for high-temperature applications.
