A387GR11 Steel Phaj Rau Boilers Thiab Cov Nkoj Siab
A387GR11steel khoom Taw qhia
SA387 Gr11 yog chromium-molybdenum alloy steel phaj rau cov hlab ntsha siab hauv Asmeskas tus qauv, thiab cov qauv siv yog: ASME SA-387/SA-387M-2019
SA387Gr11 yog qib ntawm chromium-molybdenum alloy steel phaj rau siab hlab ntsha hauv cov hlau phaj. Nws muaj cov kev ua tau zoo ntawm kev tiv thaiv hydrogen embrittlement, hydrogen corrosion, hydrogen stripping, thiab sulfide corrosion nyob rau hauv hydrogen ib puag ncig ntawm nruab nrab kub (350 ~ 480 degree), thiab muaj zoo tsis kub siab brittleness. Cov qauv siv los ntawm cov phaj hlau no yog Asmeskas tus qauv ASME thiab ASTM cov qauv. Lub xeev tus me nyuam yog feem ntau nyob rau hauv lub normalized lub xeev, thiab nws kuj yuav muab tau nyob rau hauv kub dov, tswj dov los yog quenching thiab tempering xeev.
