A516GR70 Asmeskas tus qauv siab lub nkoj steel phaj nthuav dav qhia
A516Gr70 steel phaj yog cov khoom siv hlau phaj uas siv rau cov hlab ntsha siab, uas yog ua raws li ASME cov qauv. "SA" qhia tias cov phaj hlau yog tsim rau cov hlab ntsha siab uas tau teev tseg los ntawm American Standard (ASME). "516" qhia tias nws lub zog tensile yam tsawg kawg nkaus yog 516 mpa. "Gr70" qhia tias cov khoom siv ntawm cov hlau phaj yog Gr70.
A516Gr70 steel phaj kev kho cua sov txheej txheem
A516Gr70 normalizing kev kho mob: Ua ntej, A516Gr70 steel phaj yog rhuab mus rau qhov tsim nyog kub (feem ntau 920 degree rau 980 degree) thiab tuav rau ib lub sij hawm kom ua tau ib tug uniform austenitic lub xeev ntawm cov ntaub so ntswg nyob rau hauv cov hlau phaj. Cov txheej txheem no yuav pab tshem tawm cov kev ntxhov siab nyob hauv cov phaj steel thiab txhim kho cov qauv thiab cov khoom ntawm cov khoom.
A516Gr70N Txias kev kho mob: Tom qab normalizing kev kho mob, cov hlau phaj yog txias sai heev los tsim ib tug me me martensitic qauv los ntawm cov txheej txheem normalizing. Cov txheej txheem no tsis tsuas yog pab txhim kho lub hardness thiab lub zog ntawm steel phaj, tab sis kuj txhim kho nws cov hnav thiab corrosion kuj.
A516Gr70 steel phaj zoo heev
A516Gr70 Siab zog:
Qhov tsawg kawg nkaus tensile lub zog ntawm A516Gr70N steel phaj yog 515-690 MPa (74-100 ksi), ua rau nws muaj peev xwm tiv taus siab thiab loads, haum rau kev tsim ntau yam ntawm cov hlab ntsha loj thiab cov khoom siv.
A516Gr70 Zoo toughness:
Cov phaj steel muaj qhov zoo toughness thiab tuaj yeem tswj tau qhov kev ua tau zoo nyob rau hauv kev cuam tshuam cov loads, txo qhov kev pheej hmoo ntawm kev puas tsuaj rau cov khoom siv hauv cov xwm txheej npaj txhij txog.
A516Gr70 Kev vuam zoo heev:
A516Gr70N steel phaj muaj qhov zoo tshaj plaws vuam kev ua tau zoo, tuaj yeem tswj kev ua haujlwm ruaj khov hauv cov txheej txheem vuam, txo cov khoom siv vuam tsis xws, thiab txhim kho cov pob qij txha zoo.
A516Gr70 Kev qaug zog zoo heev:
Lub phaj steel muaj kev qaug zog zoo, tuaj yeem tswj kev ua haujlwm ruaj khov nyob rau hauv lub sij hawm ntev alternating load, thiab ncua lub neej kev pab cuam ntawm cov khoom.
