303 Stainless hlau vs 302 - Qhov txawv yog dab tsi

Stainless hlau yog cov khoom siv nrov siv hauv ntau qhov kev lag luam ua tsaug rau nws cov kav ntev, corrosion-resistance, thiab kub-tiv taus zog. Hauv stainless hlau, ob qib feem ntau yog sib piv rau ib leeg: 303 thiab 302. Ob qib no tau siv dav hauv kev tsim cov txiv ntseej, bolts, screws, thiab lwm yam khoom, tab sis qhov twg zoo dua? Hauv qhov blog no, peb yuav piv 303 stainless hlau nrog 302 los pab koj nkag siab lawv qhov sib txawv thiab txiav txim siab paub.

Qhov sib txawv ntawm 303 Stainless Hlau thiab 302

Tshuaj muaj pes tsawg leeg

Ib qho ntawm qhov sib txawv tseem ceeb ntawm 303 thiab 302 yog lawv cov tshuaj muaj pes tsawg leeg. 303 muaj cov sulfur ntxiv, uas txhim kho nws cov machinability thiab ua kom yooj yim rau txiav thiab xyaum. Hauv qhov sib piv, 302 tsis muaj leej faj tab sis muaj ntau cov chromium, txhim kho nws cov khoom tiv thaiv corrosion. Koj tuaj yeem xaiv cov qib steel uas haum rau cov ntaub ntawv siv tshwj xeeb nyob ntawm cov ntawv thov.

Machineability

Txij li thaum 303 stainless hlau muaj leej faj, nws feem ntau hu ua "dawb-machining" qib, vim nws yooj yim rau txiav thiab xyaum dua li ntau lwm cov hlau tsis muaj hlau. 302 stainless hlau, thaum tsis yog dawb-machining li 303, tseem yog ib qho yooj yim rau tshuab. Cov qib no tuaj yeem tsim tau yooj yim thiab welded thiab nrov hauv kev tsim kho thiab lwm yam lag luam.

Corrosion Resistance

Ob leeg 303 thiab 302 stainless hlau qib tau paub dav rau lawv cov khoom tiv thaiv corrosion. 302 stainless hlau muaj kev tiv thaiv corrosion ntau dua li 303 vim nws cov chromium ntau dua. Qhov no ua rau nws zoo tagnrho rau cov ntawv thov uas muaj kev tiv thaiv corrosion tseem ceeb, xws li hauv kev lag luam khoom noj. Txawm li cas los xij, 303 stainless hlau kuj tuaj yeem siv rau hauv qhov chaw me me corrosive thiab tuaj yeem tiv taus ntau yam tshuaj.

Nqi

Tus nqi yog lwm yam thaum piv 303 thiab 302 stainless hlau. Feem ntau, 303 stainless hlau yog me ntsis kim dua 302 stainless hlau. Txawm li cas los xij, tus nqi ntxiv tuaj yeem tsim nyog rau kev nqis peev vim nws tuaj yeem txo tag nrho cov nqi machining thiab nce cov khoom tsim tau. Tsis tas li ntawd, tus nqi sib txawv tuaj yeem tsis pom zoo thaum xav txog kev tiv thaiv corrosion ntxiv uas 302 stainless hlau muab.

Xaus

Hauv cov ntsiab lus, 303 thiab 302 stainless hlau qib muaj cov khoom tshwj xeeb uas ua rau lawv zoo tagnrho rau cov ntawv thov tshwj xeeb. Thaum xaiv cov qib no, nws yog ib qho tseem ceeb uas yuav tau xav txog cov kev cai ntawm daim ntawv thov thiab nrhiav qhov sib npaug ntawm machinability, corrosion resistance, thiab nqi. Txawm hais tias nws yog 303 stainless hlau rau nws cov machinability lossis 302 stainless hlau rau nws cov khoom tiv thaiv corrosion, ob qib yog cov kev xaiv zoo heev rau kev tsim cov khoom zoo. Yog li, lwm zaus koj yuav tsum xaiv ntawm 303 thiab 302, koj paub tias yuav nrhiav dab tsi!
