Piv nrog rau cov qib qis xws li X52 thiab X60, X65 steel muaj:
Lub zog muaj zog ntau dua: Qhov qis tshaj tawm lub zog ntawm X65 yog 65, 000 psi (448 MPa), uas yog siab dua X52 (52, 000 psi) lossis X60 (60, 000) psi). Qhov no tso cai rau cov phab ntsa ntawm cov yeeb nkab nyias kom ua tiav thaum tswj qhov kev ntsuas tib yam, yog li txo cov nqi khoom thiab qhov hnyav. .
Kev ua tau zoo toughness: X65 steel pom zoo toughness zoo dua cov qib qis steel hauv qhov kub thiab txias. Qhov zoo tshaj plaws kub-kub toughness no ua rau nws ua haujlwm ruaj khov nyob rau hauv ib puag ncig hnyav, txo qhov kev pheej hmoo ntawm nkig tawg thiab ua kom muaj kev nyab xeeb ntawm cov kav dej hauv cov xwm txheej nyuaj.
Weldability zoo heev: Txawm hais tias nws muaj zog dua, X65 tseem tuav tau zoo weldability, uas yog ib qho tseem ceeb rau kev tsim kho kav dej thiab tu.
Kev tiv thaiv zoo heev rau hydrogen-induced cracking: Thaum lub sij hawm tsim cov txheej txheem, X65 steel tuaj yeem muaj kev tiv thaiv zoo heev rau hydrogen-induced cracking (HIC). Rau cov kev pabcuam qaub uas muaj hydrogen sulfide, qhov kev ua tau zoo no yog qhov tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab lub neej ntawm cov kav dej.
Piv nrog rau qib siab dua xws li X80 lossis X100, X65 muab:
Tus nqi-zoo: Txawm hais tias tsis muaj zog li X80 lossis X100, X70 feem ntau raug nqi ntau dua los tsim thiab siv tau yooj yim hauv thaj teb.
Dav muaj txiaj ntsig zoo: X65 muaj ntau dua thiab yooj yim dua rau hauv kev ua lag luam dua li qib siab zog ultra-siab. Qhov no ua rau qhov project muaj kev ruaj ntseg ntau dua hauv kev yuav khoom thiab kev xa khoom, txo qhov kev pheej hmoo ntawm kev tsim kho qeeb los ntawm cov khoom tsis txaus.
Yooj yim rau kev tsim thiab tsim khoom: Piv nrog cov qib siab dua ntawm cov hlau, X65 muaj cov kev cai qis dua rau kev kho cua sov thiab cov txheej txheem vuam. Hauv ntau yam kev tsim kho, qhov no ua rau nws yooj yim dua rau cov neeg ua haujlwm tsim kho kom paub thiab ua haujlwm, txo cov kev pheej hmoo zoo thiab kev tsim kho qeeb los ntawm cov txheej txheem nyuaj.
