Dab tsi yog qhov sib txawv ntawm kev siv ntawm SA334 GR 1 steel yeeb nkab thiab SA335 GR 1 steel yeeb nkab?
ASTM A334 Gr.1thiab ASTM A335 GR.1 yog ob qho tib si qauv rau cov yeeb nkab steel hlau, tab sis lawv muaj qee qhov sib txawv ntawm cov khoom siv, kev siv thiab kev ua haujlwm.
ASTM A334 GR.1 yog cov pa roj carbon tsawg, feem ntau muaj kwv yees li 0.20% carbon thiab 0.50-1.70% manganese. ASTM A335 GR.1, ntawm qhov tod tes, yog ib qho nruab nrab carbon alloy steel yeeb nkab nrog cov ntsiab lus carbon ntau dua, feem ntau ntawm 0.28-0.40% thiab manganese nruab nrab ntawm 0.50-1.70%.
ASTM A334 GR.1 cryogenic steel yeeb nkab feem ntau yog siv rau hauv kev tsim cov hlab ntsha siab, cov kav dej thiab cov tshuab ua haujlwm ntawm qhov kub txog li 600 degree F (316 degree). Nws muaj qhov zoo ntawm qhov kub thiab txias tsis zoo thiab feem ntau siv hauv cov roj av thiab tshuaj lom neeg kev lag luam. ASTM A335 GR.1 high-pressure steel yeeb nkab feem ntau yog siv rau hauv kev tsim cov cuab yeej siv siab thiab cov khoom ntawm qhov kub txog li 600 degree F (316 degree), xws li boilers, superheaters, thiab chav generators.
Vim muaj cov khoom sib txawv, ASTM A335 GR.1 steel kav feem ntau muaj zog thiab kub tsis kam tshaj ASTM A334 GR.1, thaum ASTM A334 GR.1 steel kav ua tau zoo dua nyob rau hauv qhov kub thiab txias cuam tshuam toughness.
