Cov khoom siv ntawm ASTM A335 P21 alloy steel yeeb nkab belongs rau ferritic steel, nrog rau kev sib ntxiv ntawm chromium, molybdenum, thiab qee zaum vanadium, uas yog hu ua chrome-molybdenum yeeb nkab. Cov tshuaj muaj pes tsawg leeg ntawm ASTM A335 qib P21 seamless yeeb nkab, nrog ntxiv ntawm 2.65-3.35 chromium thiab 0.80-1.06 molybdenum. Qhov tsawg kawg nkaus tensile lub zog ntawm cov kabmob yog 415 Mpa, thiab qhov tsawg kawg nkaus tawm lub zog yog 205 Mpa.
Seamless alloy steel yeeb nkab ntawm ASTM A335 qib P21 muab los ntawm GNEE yog raug rau tej yam kev mob xws li tag nrho annealing, isothermal annealing los yog normalizing quenching thiab tempering. Nws kuj muaj cov khoom ua tau zoo thiab tuaj yeem ua tiav los ntawm kev tsim cov txheej txheem xws li khoov thiab curling, thiab tsim nyog rau fusion vuam. GNEE yuav tsim raws li cov neeg siv yuav tsum tau ua thiab xyuas kom meej tias qhov zoo ntawm cov yeeb nkab steel ua tau raws li cov qauv ASTM.
