LR Qib DH62 yog siab heev -lub zog, TMCP los yog quenched thiab tempered steel phaj ntawv pov thawj los ntawm LR. Cov hlau no yog tsim los rau cov txheej txheem tseem ceeb tshaj plaws hauv kev tsim cov nkoj niaj hnub thiab kev ua haujlwm sab nrauv, muab lub zog tshwj xeeb - rau - qhov hnyav piv rau qhov hnyav tshaj qhov txo qis thiab kev them nyiaj kom zoo.
Zoo Tsawg-Temperature Toughness: Raws li Qib D steel, DH62 tau lees paub qhov cuam tshuam zoo ntawm qhov kub thiab txias mus rau -20℃/ -4℃F. Qhov no ua rau nws tsim nyog rau kev thauj mus los thoob ntiaj teb thiab kev ua haujlwm hauv cov dej txias.
Advanced Weldability: Txawm hais tias nws lub zog siab, cov hlau yog tsim los nrog kev ua tib zoo tswj cov tshuaj muaj pes tsawg leeg (thiab feem ntau nyob rau hauv TMCP mob) kom ntseeg tau tias cov pa roj carbon tsawg. Qhov no ua kom yooj yim weldability zoo, txawm hais tias nws yuav xav tau cov txheej txheem vuam tshwj xeeb dua li qis dua - qib zog los khaws cov khoom hauv tshav kub- thaj tsam cuam tshuam.
