Low-Alloy Steels Phau Ntawv Electrode E9018-B92 duplex stainless hlau tshuaj tanker weld
Vim qhov sib ntxiv ntawm me me ntawm Nb thiab V, nws tuaj yeem muaj kev nkag siab zoo heev thaum siv ntawm 600C kub.
Tsawg hydrogen potassium tshuaj tawv nqaij, tshuaj tawv nqaij hloov pauv alloy
AC tshwj xeeb, tuaj yeem txuas rau txhua txoj haujlwm.
