12CrMo kub-resistant steel yeeb nkabyog pearlite-type heat-strength steel nrog zoo txias strain plasticity thiab machinability, thiab siv tau weldability. Nws yog siv los tsim cov kav dej loj nrog qhov ntsuas qhov ntsuas txog li 510 degree, cov kav dej superheated nrog lub raj phab ntsa kub txog 540 degree, thiab lwm yam. Nws kuj tseem siv tau los ua ntau yam elastic uas ua haujlwm ntawm qhov kub thiab txias.
12CrMo steel yeeb nkab muaj pes tsawg leeg: Lub npe "12CrMo" qhia cov tshuaj muaj pes tsawg leeg ntawm cov hlau. Hauv qhov no, nws feem ntau muaj txog 1.0% mus rau 1.2% chromium (Cr) thiab li ntawm 0.3% rau 0.6% molybdenum (Mo) ua lub ntsiab alloying cov ntsiab lus.
12CrMo alloy steel yeeb nkab yog cov yeeb nkab uas muaj zog, siab kub, siab siab. Vim nws qhov tshwj xeeb zoo hauv cov tshuaj muaj pes tsawg leeg, lub cev muaj zog, cov khoom siv kho tshuab, thiab lwm yam, nws yog dav siv hauv roj av, tshuaj lom neeg kev lag luam, hluav taws xob fais fab, aerospace thiab lwm yam kev lag luam.
