ASTM A302 GR.C Mn-Mo-Ni Alloy Pressure Vessel steel phaj

ASTM A302 Qib C yog Manganese-molybdenum-nickel alloy boiler steel phaj. Cov hlau ntawm A302 Qib C yuav tsum raug tua thiab yuav tsum ua raws li qhov yuav tsum tau ua kom zoo. Lub boiler steel phaj A203 Qib C yuav tsum raug kuaj nruj los txiav txim siab lub zog tensile, tawm lub zog, thiab elongation. Thaum dov SA302 Qib C raws li kev qhia steel NACE MR0175, HIC xeem, SCC, SSC xeem yuav tsum tau ua nyob rau hauv peb lub zeb lab rau gurantee SA302 Qib C steel khoom. Lwm yam kev xeem techincal ntxiv, xws li PWHT, DWTT, Kev ntsuas kub siab yuav tsum raug xaiv los ntawm cov neeg siv kawg yog tias lawv xav tau.
Thickness: 6mm-300mm,
Dav: 1500mm txog 4050mm,
Ntev: 3000mm txog 15000mm
