18MnMo4-5 steel phaj yog European txheem steel phaj rau cov hlab ntsha siab. Qee cov ntsiab lus alloying xws li manganese thiab molybdenum tau ntxiv rau cov hlau phaj kom muab nws cov khoom siv zoo dua qub thiab tiv thaiv corrosion. Nws yog dav siv hauv kev lag luam roj thiab roj, kev lag luam hluav taws xob, kev lag luam tsheb thiab lwm yam kev lag luam.
18MnMo4-5 steel phaj siv tus qauv: EN10028-2. Cov txheej txheem European no qhia txog qhov yuav tsum tau ua rau cov hlau tsis-alloy thiab alloy steel tiaj tus khoom uas tuaj yeem welded nrog cov txheej txheem kub kub rau cov hlab ntsha.
