4140 Q&T yog cov hlau hauv tsev neeg ntawm SAE steel qib, raws li tau teev tseg los ntawm Society of Automotive Engineers (SAE). Alloying cov ntsiab lus suav nrog chromium thiab molybdenum, thiab vim li ntawd cov ntaub ntawv no feem ntau hu ua chromoly steel (cov qauv sib txawv xws li chrome-moly, CrMo, CRMO, CR-MOLY, thiab zoo sib xws). Lawv muaj lub zog zoo rau qhov hnyav piv thiab muaj zog ntau dua thiab nyuaj dua li tus qauv 1020 steel, tab sis tsis yooj yim welded (xav tau ua ntej thiab tom qab vuam thermal kho kom tsis txhob txias tawg). Thaum cov qib ntawm cov hlau no muaj chromium, nws tsis muaj ntau txaus los muab cov corrosion kuj pom nyob rau hauv stainless hlau. Cov txheej txheem quenching hardens cov hlau, thaum cov txheej txheem Tempering rov qab qee qhov ductility thiab tshem tawm qee qhov brittleness tau txais thaum kho cua sov.
Cov khoom no yog TG & P uas yog tig, av thiab Polished rau ib tug nruj txoj kab uas hla kam rau ua.
