河钢舞阳钢鉄WH60A钢板质量可靠,性能优于Q460高强钢板

1、WH60A属于低合金高强度钢板,高强度焊接钢结构钢板,通常被叫做高强板或高强钢。设计之初是为满足国家大型煤矿设备生产企业矿用液压支架而特别开发的专用产品;钢的牌号由代表产地的首位字母、强度等级字母、质量等级符号三个部分组成。其中:W表示舞钢;H表示公斤级;60表示公斤级数值;A表示产品质量等级(无冲击要求)。WH60系列还包含WH60B、WH60C、WH60D、WH60E。2、WH60A执行企业标准:WH60A执行企业标准、、WH60A交货状态:钢板以控轧或热处理状态交货 WH60A/B/C/D:属于高强度焊接型钢板,通常称为“高强板”亦叫做“高强钢”。设计之初是为满足国家大型煤矿设备生产企业矿用液压支架而特别开发的。焊接性能非常好。钢的牌号的组成由首位字母、强度等级字母、质量等级符号三个部分组成。其中:“W”表示舞钢专有标识;“H”表示公斤级;60表示公斤级数值;A表示产品质量等级(此等级表示没有冲击要求,不做特殊处理);对应国标牌号Q460高强度钢板。WH60系列包含了以下几个级别,随着等级的划分,冲击性能要求不同划分:WH60B、WH60C、WH60D、WH60E。这些材质均用来生产制造工程机械以及矿山机械、煤矿机械如液压支架、平板运输车、挖掘机支撑臂等。WH60A钢板的执行标准为:(舞钢产品技术协议),WH60A交货状态为:控轧、正火等(具体根据客户的具体要求来订轧)。WH60A/B/C/D/E技术要求:探伤、厚度方向性能要求、高强度高韧性要求等钢板。WH60的化学成分及机械性能工程机械和高性能要求高强度结构钢WH60技术条件说明:本技术条件适用于厚度不大于100mm的工程机械用焊接结构钢板。(需要更大厚度,需要技术审批)GB/钢的化学分析用试样法及成品化学成分允许偏差GB/T223钢铁及合金化学分析方法GB/金属拉伸试验方法GB/金属夏比缺口冲击试验方法GB/金属弯曲试验方法GB/钢板和钢带验收、包装、标志及质量证明书的一般规定GB/热轧钢板和钢带尺寸、外形、重量及允许偏差GB/钢及钢产品力学性能试验取样位置及试样制备GB/碳素结构钢及低合金钢热轧厚钢板和钢带3尺寸、外形、重量及允许偏差范围说明钢板的尺寸、外形、重量及允许偏差应符合GB/T709的规定。4./B/C/D/E化学成分材质牌号C元素Si元素Mn元素P元素S元素WH60A钢板≤0.20≤0.60≤1.8≤0.025≤0.钢板≤0.钢板≤0.钢板1)碳当量(Ceq,%)计算公式如:Ceq(%)=C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/154./B/C/D/E冶炼方法电炉+炉外精炼。4./B/C/D/E状态钢板以控轧或热处理状态。力学及工艺性能钢板的力学性能及工艺性能应符合表2规定。级别规格拉伸性能纵向180°弯曲试验交货状态碳当量厚度≤63mm厚度>正火、正火加回火、回火≤0.53≤0.54控轧≤0.50注:1) 可加入其他合金元素。
