Stainless hlau phau ntawv electrode E320-16 weld fabrication khoom
Daim ntawv thov
Nws yog qhov tsim nyog rau ntau lub sijhawm uas sulfuric acid, sulfite thiab lawv cov ntsev yuav tsum tau tiv thaiv corrosion hnyav. Nws yog feem ntau siv rau vuam cov ntaub ntawv uas zoo sib xws, xws li Alloy20 thiab UNS N08020, thiab lwm yam. Nws yog dav siv nyob rau hauv kev tsim cov tshuaj thiab hydrogen ntau lawm cov khoom.
