ASTM A517 Qib B thiab Qib E yog ob qho tib si siab - lub zog, quenched thiab tempered alloy steel daim hlau rau fusion-welded siab hlab ntsha, tab sis lawv txawv nyob rau hauv lawv cov ntsiab alloying thiab tej zaum thickness ranges, nrog rau ob qho tib si muab lub zog zoo heev (xws li, 100 ksi min yield rau thinner seem, ua rau lawv lub tswv yim rau cov khoom siv hluav taws xob) Qib E feem ntau muaj Molybdenum thiab Chromium rau kev txhim kho cov khoom.

Qhov Tseem Ceeb Zoo sib xws
Txuj: Ob leeg poob rau hauv ASTM A517, ib qho kev qhia tshwj xeeb rau siab - lub zog, quenched, thiab tempered alloy steel phaj.
Daim ntawv thov: Feem ntau yog siv rau fusion-welded boilers thiab siab hlab ntsha uas xav tau lub zog siab.
Thaum tshav kub kub kho: Ob leeg undergo quenching thiab tempering rau superior mechanical zog.
Mechanical Strength: Ob leeg muaj peev xwm ua tau zoo yield zog (piv txwv li, 100 ksi rau thicknesses txog 2.5 nti).
Toughness: Ob leeg yuav tsum tau Charpy V-qhov ntsuas qhov cuam tshuam rau qhov tawv.
Qhov txawv tseem ceeb
Alloy Composition: Cov qib sib txawv hauv A517 muaj qhov sib txawv ntawm cov khoom sib txawv (xws li Molybdenum, Chromium, Vanadium, Nickel) rau cov khoom siv, nrog Qib E feem ntau muaj cov kev xav tau tshwj xeeb rau kev ua haujlwm siab dua.
Thickness: Qib B tej zaum yuav raug teev rau cov phaj nyias (piv txwv li, txog li 1.25 ntiv tes hauv qee kis), thaum Qib E muaj nyob rau hauv cov ntu tuab (txog 6 ntiv tes lossis ntau dua) nrog cov qib sib xws, sau ntawv SSAB, SSAB, thiab SSAB.
Cov Khoom Tshwj Xeeb: Qib E feem ntau tsom rau lub zog siab dua thiab tawv tawv rau cov xwm txheej huab cua, nrog rau qhov yuav tsum tau muaj kev nthuav dav ntxiv, thaum Qib B yog qhov ua tau zoo rau kev siv cov hlab ntsha dav dav.
