Khoom Taw qhia

UNS S31803 Khoom sivyog ib tug duplex stainless hlau nrog 22% chromium cov ntsiab lus. Qib 2205 steel kav yog resistant rau localized corrosion thiab pitting. Vim tias qhov sib ntxiv ntawm molybdenum hauv cov ntaub ntawv duplex, lawv muaj tsawg heev hauv cov tshuaj chloride-nplua nuj. Cov ntsiab lus tsis tshua muaj npib tsib xee hauv cov khoom siv alloy S31803 ua rau nws hnav. Piv nrog rau cov qib 304/316 stainless hlau, nws muaj ob zaug lub zog thiab txhim kho corrosion kuj, thiab tuaj yeem tiv taus qhov siab thiab siab hauv hydraulic systems.

Alloy 2205 S31803 Yeeb Nkab Siv Tau Kub

S31803 duplex steel feem ntau haum rau siv ntawm qhov kub ntawm -50 degree thiab 250 degree . Tsis tas li ntawd, kev hloov mus rau brittleness yuav tshwm sim, ua rau muaj kev cuam tshuam qis dua.
