ASME SA514/ SA514M Grade E quenched and tempered Alloy steel plates are high yield strength steel of structural quality in thickness of 150mm and under intended primarily for use in welded bridges and other structures. ASME SA514/ SA514M Grade E quenched and tempered alloy steel plates are mainly used to make mechanical device and other structural elements and so on drilling machine, power shovel, electricity drive wheel counter- mine trolley, mineral product automobile, car loader, etc.
ASME SA514/ SA514M Grade E quenched and tempered alloy steel plate chemical composition:
