本文着重讨论了GB5213—85深冲压用冷轧薄钢板和带钢,就力学性能及显微组织与国外先进标准JISG3141(1977)、DIN1623—1(1983)和ISO3574—1976做了对比。发现GB5213—85对力学性能及显微组织的规定远比其他各国标准严格,影响了国产深冲钢板的生产。建议参照国外先进标准对GB5213—85中关于力学性能和显微组织部分加以修订,以尽快向国外先进标准靠拢。
This article focuses on the GB5213-85 deep drawing cold-rolled steel sheet and strip, on the mechanical properties and microstructure with foreign advanced standards JISG3141 (1977), DIN1623-1 (1983) and ISO3574-1976 made a comparison. Found GB5213-85 on the mechanical properties and microstructure regulations far more stringent than other national standards, affecting the domestic deep-drawn steel production. Proposed reference to foreign advanced standards on GB5213-85 on the mechanical properties and microstructure to be amended to move closer to foreign advanced standards.
