Nws yog siv rau hauv ntau lub lag luam, suav nrog tsheb, aerospace, kev tsim kho, thiab kev ua zaub mov. Txawm li cas los xij, tsis yog tag nrho cov hlau tsis muaj steel yog tsim sib npaug. Ob hom kev siv ntau tshaj plaws yog 309 thiab 316, uas sib txawv ntawm cov tshuaj muaj pes tsawg leeg thiab cov yam ntxwv. Yog tias koj nyob hauv kev ua lag luam stainless hlau rau koj qhov project tom ntej, xav txog qhov sib txawv ntawm ob hom no los txiav txim seb qhov twg yog qhov zoo tshaj rau koj cov kev xav tau.

Stainless hlau 309 yog dab tsi?

Stainless hlau 309 yog ib qho kub-resistant stainless hlau alloy feem ntau siv hauv kev lag luam thiab kev siv. Nws muaj kev tiv thaiv corrosion zoo heev thiab zoo oxidation thiab ductility yam ntxwv, ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau kev lag luam tuav cov kev hloov kub ntau zaus. Qib no ntawm stainless hlau tuaj yeem raug nqi-zoo welded, zoo li tus, machined thiab fabricated rau ntau yam.

Stainless hlau 316 yog dab tsi?

Stainless hlau 316 yog qib austenitic ntawm cov hlau uas muaj nyob nruab nrab ntawm 16-18% chromium, 10-14% nickel, thiab 2-3% molybdenum. Nws muaj kev tiv thaiv corrosion zoo heev thiab lub zog rau cov ntawv thov hauv cov cheeb tsam hnyav xws li kev lag luam marine lossis tshuaj ua lag luam. Tsis tas li ntawd, nws muaj cov khoom zoo tshaj plaws, xws li tshwj xeeb weldability thiab formability, uas ua rau nws nyiam xaiv rau ntau qhov kev tsim kho.

Qhov sib txawv ntawm Stainless Hlau 309 thiab 316
Tshuaj muaj pes tsawg leeg

Ib qho ntawm qhov sib txawv loj tshaj plaws ntawm 309 thiab 316 stainless hlau yog lawv cov tshuaj muaj pes tsawg leeg. 309 stainless hlau muaj 22% chromium thiab 12% npib tsib xee, thaum 316 stainless hlau muaj 16% chromium, 10% nickel, thiab 2% molybdenum. Ntxiv molybdenum teeb 316 sib nrug ntawm 309, ntxiv rau nws cov corrosion kuj. Qhov no txhais tau hais tias 316 yog qhov zoo dua rau cov ntawv thov uas nws yuav raug rau cov tshuaj hnyav thiab dej ntsev, thaum 309 feem ntau yog siv rau hauv qhov chaw zoo dua.

Lub zog thiab Hardness

Ob leeg 309 thiab 316 stainless hlau muaj qib siab ntawm lub zog thiab hardness, uas ua rau lawv zoo tagnrho rau cov ntawv thov uas muaj zog yog qhov tseem ceeb. Txawm li cas los xij, 309 stainless hlau muaj lub zog ntau dua li 316, uas txhais tau tias nws tuaj yeem tiv taus kev ntxhov siab ntau dua ua ntej nws deforms. Qhov no ua rau 309 qhov kev xaiv zoo rau cov ntawv thov uas muaj qhov kub thiab txias.

Machinability thiab Weldability

Hais txog machinability thiab weldability, 316 stainless hlau feem ntau suav hais tias zoo tshaj rau 309. Qhov no yog vim 316 muaj cov pa roj carbon tsawg, uas ua rau nws yooj yim dua rau tshuab thiab txo qhov kev pheej hmoo ntawm vuam-vim kev ntxhov siab tawg. Txawm li cas los xij, 309 tseem yooj yim ua haujlwm nrog. Nws yog cov hlau ntau yam uas tuaj yeem tsim tau yooj yim, zoo li, thiab welded kom haum rau feem ntau cov ntawv.

Nqi

Thaum kawg, tus nqi tseem ceeb thaum xaiv ntawm 309 thiab 316 stainless hlau. Vim nws cov ntsiab lus ntau dua nickel thiab molybdenum, 316 feem ntau yog kim dua 309. Txawm li cas los xij, tus nqi no feem ntau raug lees paub los ntawm kev ua kom muaj zog corrosion thiab durability uas 316 muaj. Yog tias koj qhov project yuav raug cuam tshuam rau qhov chaw hnyav lossis xav tau qib siab ntawm kev tiv thaiv corrosion, tus nqi ntawm 316 yuav tsim nyog.

Xaus

Stainless hlau yog cov khoom tseem ceeb uas tuaj yeem siv rau hauv ntau yam kev siv. Thaum txiav txim siab ntawm 309 thiab 316 stainless hlau, nws yog ib qho tseem ceeb uas yuav tau xav txog yam xws li tshuaj muaj pes tsawg leeg, lub zog thiab hardness, machinability thiab weldability, thiab nqi. Txhua tus muaj cov yam ntxwv tshwj xeeb uas ua rau nws zoo tagnrho rau kev siv sib txawv. Thaum kawg, qhov kev txiav txim siab yuav nyob ntawm koj qhov kev xav tau tshwj xeeb thiab ib puag ncig uas yuav siv cov hlau. Los ntawm kev nkag siab txog qhov sib txawv ntawm ob hom nrov stainless hlau, koj tuaj yeem txiav txim siab thiab xaiv cov hlau uas yuav ua haujlwm zoo tshaj plaws rau koj qhov project.
