30crmnsiA alloy seamless steel yeeb nkabyog cov yeeb nkab steel hlau uas muaj chromium, molybdenum, silicon, nitrogen thiab lwm yam khoom. Cov ntsiab lus chromium kuj tseem siab, txog 2.0%-3.0%, cov ntsiab lus silicon yog li 0.2%-0.8%. , thiab cov ntsiab lus molybdenum yog li ntawm 0.2%{{10}}.3%, nitrogen cov ntsiab lus yog li 0.1%-0.2%. Tsis tas li ntawd, cov yeeb nkab steel hlau kuj muaj qee yam ntawm carbon, phosphorus, sulfur thiab lwm yam khoom.
30crmnsiA txias drawn steel yeeb nkab muaj lub zog siab thiab toughness, nws lub zog tensile thiab yield point yog siab dua li cov hlau zoo tib yam, thiab nws kuj muaj qhov zoo ductility thiab qaug zog. Cov yeeb nkab steel hlau no tseem tuaj yeem tswj kev ua haujlwm ruaj khov txawm tias nyob rau hauv cov xwm txheej ntawm cov kabmob loj thiab kev nyuaj siab.
Txij li thaum 30crmnsiA gas cylinder steel yeeb nkab muaj cov ntsiab lus xws li chromium thiab molybdenum, nws muaj kev tiv thaiv corrosion zoo. Nyob rau hauv corrosive media xws li acids, alkalis, thiab ntsev, ib tug ntom oxide zaj duab xis yuav tsim nyob rau saum npoo ntawm alloy steel yeeb nkab, uas yuav zoo tiv thaiv corrosion ntxiv.
