Qhov sib txawv ntawm 303 thiab 303e stainless hlau

Thaum xaiv cov hlau tsis xeb rau high - ceev lub tshuab ceev lossis preisi 303 thiab ai 303 thiab ai 303se yog ob txoj kev xaiv nrov. Ob txoj kev kawm qib rau Austenitic 18 {- 8} 8- tus cwj pwm zoo, thiab corrosion tsis kam.
Txawm li cas los xij, hloov maj mam sib txawv hauv lawv cov tshuaj sib xyaw ua ke - ua rau cov txiv neej sab hauv 303 thiab sel) hauv 303se}, nto tiav, thiab corrosion tsis kam.

 

Dab tsi yog 303 stainless hlau?
303 Stainless hlau yog ib tug Austenitic stainless hlau paub rau nws zoo heev machinity, nws tau los ntawm kev sib ntxiv ntawm cov leej faj. Thaum qhov no ua rau nws txiav tau yooj yim thiab daim ntawv, nws yog qhov tsis zoo los ntawm kev kho cua sov, ua rau nws zoo tagnrho rau cov ntu nrog cov khoom siv ua kom zoo nkauj.

 

Dab tsi yog 303se Stainless hlau?
Lub tshuab hluav taws xob tiv thaiv stainless hlau yog ib qho kev hloov kho tshiab ntawm qib 303} Qhov kev hloov kho no tseem muaj mob khaub thuas zoo dua- sib sau cov khoom dua 303, thiab nws khaws lub zog zoo thiab corrosion tsis kam.

 

1. Tshuaj lom neeg sib xyaw

303 txhim kho tshuab luam ntawv nrog Sulphur (s) .303se tau siv Selenium (SE), ua rau muaj kev huv si thiab corrosion zoo.

Corrosion Kuj

Txawm hais tias ob tus menyuam kawm nyob rau 300-series stainless hlau, cov leej faj hauv 303 me ntsis qis qis nws corrosion tsis kam piv rau 303se. Selenium tsis ua tib hom sulfide suav, tso cai ua yeeb yaj kiab ua kom huv si los ua cov duab hlau.

 

Kev Kho Cua Sov
