ASTM A333 Qib 4 yog cov yeeb nkab uas tsis tshua muaj hlau uas muaj npib tsib xee ua lub ntsiab alloying, nrog rau manganese, phosphorus, sulfur, silicon thiab lwm yam khoom. Nws muaj cov cuab yeej zoo heev thiab kev tiv thaiv corrosion hauv qhov kub thiab txias.
A333 Qib 4 alloy steel yeeb nkabtau teev cov cuab yeej cuab tam nrog rau qhov tsawg kawg nkaus lub zog ntawm 240 MPa (35, 000 psi) thiab lub zog tensile yam tsawg kawg nkaus ntawm 415 MPa (60, 000 psi).
ASTM A333 cov kav dej kub kub uas tau muab los ntawm GNEE kuj tau dhau los ua Charpy V-notch cuam tshuam kev sim kom ntseeg tau tias cov khoom muaj peev xwm nqus tau lub zog ntawm qhov kub thiab txias. Qhov kev sim no yog qhov yuav tsum tau ua tseem ceeb rau cov kav dej steel kom ntseeg tau tias lawv muaj kev ntseeg siab thiab kev nyab xeeb hauv kev siv tswv yim.
ASTM A333 Qib 4 cryogenic steel yeeb nkab feem ntau yog siv los tiv thaiv qhov kub thiab txias qis li -50 degree (-75 degree F).
Cov ntawv thov feem ntau rau ASTM A333 Qib 4 steel yeeb nkab suav nrog cov tso tsheb hlau luam cryogenic, cov txheej txheem txheej txheem cryogenic thiab cov kav dej ua haujlwm hauv qhov chaw cryogenic. Cov ntawv thov no suav nrog kev tsim khoom thiab kev thauj mus los ntawm ntau yam khoom siv cryogenic thiab tshuab hauv thaj chaw xws li roj av, tshuaj lom neeg thiab cov nkev.
