Txias Rolled DIN 1.4438 Stainless Hlau Yeeb Nkab
1.4438 steel yeeb nkabyog molybdenum-muaj stainless hlau nrog zoo heev corrosion kuj thiab lub zog. Nws yog dav siv nyob rau hauv ib puag ncig corrosive heev nyob rau hauv chemical kev lag luam, zaub mov ua thiab lwm yam teb. 1.4438 stainless hlau yeeb nkab muaj kev tiv thaiv kev ntxhov siab corrosion, muab nws superior durability nyob rau hauv corrosive ib puag ncig xws li tshuaj thiab tshuaj.
1.4438 acid-resistant steel yeeb nkab muaj kev tiv thaiv zoo rau pitting corrosion thiab intergranular corrosion nyob rau hauv high-kub ib puag ncig xws li seawater desalination thiab ntsev kev lag luam.
Cov hom lag luam hauv tsev thiab txawv teb chaws ntawm 1.4438 yog: X2CrNiMo18-15-4, 317L thiab SUS317L. 1.4438 muaj qhov zoo thermal thiab txias qaug zog tiv thaiv hauv cov cua txias, cov khoom siv hluav taws xob thiab lwm yam khoom siv, txuas ntxiv lub neej kev pab cuam.
1.4438 seamless stainless hlau yeeb nkab plays lub luag haujlwm tseem ceeb hauv kev tiv thaiv ib puag ncig vim tias nws cov corrosion kuj pab txo cov pa phem ntawm ib puag ncig. Cov tshuaj muaj pes tsawg leeg ntawm 1.4438 stainless hlau puas yeeb nkab yog: Cr 17-19%, Ni 13-16%, Mo 2.5-3.0%, C Tsawg dua los yog sib npaug rau { {9}}.03%. 1.4438 tuaj yeem txhim kho nws cov kev tiv thaiv corrosion los ntawm kev ntxiv cov ntsiab lus hlau xws li molybdenum thiab tungsten kom hloov mus rau qhov chaw thov hnyav dua.
