Nyob rau hauv cov tshuaj muaj pes tsawg leeg ntawm ASTM A333 Qib 6 cov qauv steel yeeb nkab, lub ntsiab lus twg yog qhov tseem ceeb rau qis -kub toughness?
Nyob rau hauv cov tshuaj muaj pes tsawg leeg ntawmASTM A333 Qib 6 cov qauv steel yeeb nkab, manganese yog lub ntsiab tseem ceeb rau qis -kub toughness. Nws txhim kho lub zog thiab cuam tshuam ntawm cov yeeb nkab steel hauv qab xoom degrees Celsius.
Dhau li ntawm qis- qhov kub thiab txias, lwm yam zoo li cas ASTM A333 Qib 6 cov qauv steel yeeb nkab muaj?
Dhau li ntawm qis-kub kev ua haujlwm,ASTM A333 Qib 6 cov qauv steel yeeb nkabkuj muaj lub zog siab, durability, thiab weldability zoo heev, ua rau nws tsim nyog rau kev thov xws li siab - ib puag ncig siab thiab ntau yam kev lag luam siv. Nws txhim kho toughness thiab tsis kam rau nkig tawg kuj ua rau nws ntseeg tau.
Puas muaj qhov yuav tsum tau ua rau carbon sib npaug hauv ASTM A333 Qib 6 cov qauv steel yeeb nkab? Vim li cas?
Yog, qhov siab tshaj plaws carbon sib npaug (CE) yuav tsum tau rauASTM A333 Qib 6 steel yeeb nkabyog 0.43% kom ntseeg tau zoo weldability thiab txhua yam khoom ntawm qhov kub thiab txias. Cov mis CE txiav txim siab qhov sib xyaw ua ke ntawm cov pa roj carbon thiab lwm yam alloying xws li manganese, chromium, molybdenum, npib tsib xee, thiab tooj liab, uas cuam tshuam rau cov khoom ntawm cov hlau.
Dab tsi yog qhov txawv ntawm ASTM A333 Qib 6 cov qauv steel yeeb nkab thiab A333 Qib 3 steel yeeb nkab?
Qhov sib txawv tseem ceeb nyob hauv lawv cov tshuaj muaj pes tsawg leeg.ASTM A333 Qib 6 steel yeeb nkabyog ib hom nickel-dawb qis- carbon steel, thaum Qib 3 steel yeeb nkab yog qis- carbon alloy steel nrog ntau dua nickel thiab silicon cov ntsiab lus.
Cov khoom siv kho tshuab ntawm ASTM A333 Qib 6 cov qauv steel yeeb nkab puas tuaj yeem txhim kho los ntawm kev kho cua sov?
Yog, mechanical zog ntawmASTM A333 Qib 6 steel yeeb nkabtuaj yeem txhim kho thiab tswj tau los ntawm kev kho cua sov. Qhov no yog txheej txheem tsim nyog los xyuas kom meej tias qhov ua tau zoo ntawm cov khoom siv no nyob rau hauv qis - daim ntawv thov kub. Cov kev kho cua sov xws li normalizing, normalizing ua raws li tempering, thiab quenching ua raws li tempering yog siv los tswj cov microstructure ntawm cov khoom thiab txhim kho cov khoom xws li cuam tshuam toughness, tensile zog, thiab yield zog.
