SS309 Seamless Tubes

Alloy 309 stainless hlauyog ib tug high-alloy stainless hlau uas muaj siab chromium thiab npib tsib xee thiab muaj zoo kub tsis kam thiab corrosion kuj. Nws yog tsuas yog siv nyob rau hauv high-temperature khoom thiab pipelines. Cov qib sib xws ntawm 309 stainless hlau kav yog: SUS309, UNS S30900.
309 Stainless Hlau Round Yeeb Nkab muaj qhov zoo hydrogen embrittlement tsis kam thiab tuaj yeem tswj cov khoom zoo thiab corrosion kuj nyob rau hauv high hydrogen ib puag ncig, ua rau nws haum rau hydrogen zog teb. Cov khoom siv 317l Stainless Hlau Yeeb Nkab muaj qhov ua tau zoo los tiv thaiv kev ua haujlwm corrosion thiab tuaj yeem tswj tau zoo corrosion kuj nyob rau hauv condensate dej ib puag ncig.
Thaum tshav kub kub-resistant 309 stainless hlau yeeb nkab muaj zoo thermal deformation kuj nyob rau hauv qhov kub thiab txias ib puag ncig thiab tuav ruaj khov loj thiab zoo. tuaj yeem tiv taus qhov kub thiab txias ntawm 980 degree. Feem ntau siv hauv boilers, tshuaj lom neeg kev lag luam thiab lwm yam lag luam. 309 steel yeeb nkab muaj kev tiv thaiv corrosion zoo thiab tuaj yeem tiv thaiv corrosion hauv cov tshuaj uas muaj chloride ions. Nws yog tsim rau kev kho dej hiav txwv, tshuaj lom neeg kev lag luam thiab lwm yam kev lag luam scenarios.

309 SS Round Pipe SS 309 Polished Pipe

Alloy 309 muaj kev tiv thaiv corrosion zoo heev vim nws cov chromium siab thiab tsis tshua muaj npib tsib xee, tso cai rau nws siv rau hauv cov huab cua uas muaj leej faj ntawm qhov kub txog li 1832 degree F (1000 degree). Txawm li cas los xij, nws tsis pom zoo siv rau hauv cov huab cua uas muaj carburized heev vim nws pom tias muaj kev tiv thaiv tsis zoo rau cov pa roj carbon uptake. Txawm li cas los xij, Alloy 309 tseem tsim nyog rau lub teeb oxidation, nitriding, solidification thiab thermal cycling daim ntaub ntawv, tab sis yuav tsum tau saib xyuas kom txo nws qhov siab tshaj plaws kev pab cuam kub.
