本标准适用于厚度为15~150mm,屈服点不大于51kgf/mm2(500N/mm2)的镇静钢的钢板。对于厚度小于15mm和大于150mm或屈服点大于51kgf/mm2(500N/mm2)的钢板应在订货时协商。
本标准是对有关标准的钢板要求做厚度方向性能试验时的补充规定。
用于造船、海上采油平台、锅炉和压力容器等某些重要焊接构件的钢板,不仅要求沿宽度方向和长度方向有一定的力学性能,而且要求厚度方向有良好的抗层状撕裂性能。钢板的抗层状撕裂性能采用厚度方向拉力试验的断面收缩率来评定。
1. Introduction
1.1 The steel plate, used for certain crucial welding assembly, such as shipbuilding, outshone production platform, boiler and pressure vessel, not only require certain mechanical property of its broad ways and length heading ,but also satisfactory lamellar tearing- resistant performance of its thickness. The steel plate' performance in the lamellar tearing resistance aspect can be assessed by reduction in area when doing tension test of through-thickness.
1.2 This standard is applicable to killed steel plate with thickness between 15mm and 150mm, and with yield point no larger than 51 kgf/mm2 (500n/mm2). For the steel plate which the thickness is less than 15mm or greater than 150mm, or the yield point is greater than 51kgf/mm2 (500N/mm2), specific requirements shall be negotiated at order time.
1.3 The standard serves as supplementary provision for relevant standard steel plate requiring through-thickness property test.
