Cov kav hlau twg tuaj yeem txhais tau tias yog cov kav hlau tsis tshua muaj hlau?

Ntawm cov yeeb nkab steel hlau, thaum ntxiv cov alloys xws li npib tsib xee, chromium thiab tag nrho molybdenum alloy cov ntsiab lus tuaj yeem nyob ntawm 2.07% mus rau theem tam sim ntawd cov hlau tsis muaj steel, uas muaj tsawg kawg yog 10% Cr, lawv txhais tau tias yog cov hlau tsis tshua muaj hlau.

• Chromium-molybdenum alloy steel yeeb nkab

Qhov no series ntawm cov hlau tsis tshua muaj hlau muaj 0.5% mus rau 9% Cr thiab 0.5% mus rau 1% Mo. Qhov nruab nrab carbon cov ntsiab lus yog tsawg dua 0.20%.Cov ntsiab lus Cr ua rau nws muaj peev xwm tiv thaiv oxidation thiab tiv thaiv corrosion, thiab Mo ua rau nws tsis kam nyob rau hauv qhov kub thiab txias;steel mov tej yam kev mob feem ntau yog tshem tawm los ntawm annealing los yog standardization thiab tempering txheej txheem.Chromium-molybdenum alloy steel kav tau siv dav hauv kev lag luam roj thiab roj, cov chaw tsim hluav taws xob thiab lwm yam kev siv kub.
