sphc是什么材料
SPHC——首位S 为钢Steel 的缩写,P 为板Plate 的缩写,H 为热Heat 的缩 写,C 商业Commercial 的缩写,整体表示一般用热轧钢板及钢带;
SPHC代表的是的热轧钢板(它对应的冷轧板就是SPCC),相当于国标GB699(优质碳素结构钢国家标准)中的10#、15#钢的热轧板,他们的含碳量范围是0.1-0.15%左右;
热轧钢板分为厚板(厚度大于4mm)和薄板(厚度为0.35~4mm)两种;热轧的终止温度一般为800~900,之后一般在空气中冷却,因而热轧状态相当于正火处理。热轧状态交货的金属材料,由于表面覆盖有一层氧化膜,因而具有一定的耐蚀性,储运保管的要求不像冷拉(轧)交货的材料那样严格,如大、中型型钢、中厚钢板可以在露天货场或经苫盖后存放。

扩展资料
用连铸板坯或初轧板坯作原料,经步进式加热炉加热,高压水除鳞后进入粗轧机,粗轧料经切头、尾、再进入精轧机,实施计算机 控制轧制,终轧后即经过层流冷却(计算机控制冷却速率)和卷取机卷取、成为直发卷。直发卷的头、尾往往呈舌状及鱼尾状,厚度、 宽度精度较差,边部常存在浪形、折边、塔形等缺陷。其卷重较重、钢卷内径为760mm。
热轧(英文:hotrolling)是相对于冷轧而言的,冷轧是在再结晶温度以下进行的轧制,而热轧就是在再结晶温度以上进行的轧制。热轧,是以板坯(主要为连铸坯)为原料,经加热后由粗轧机组及精轧机组制成带钢。

SPHC钢标准:JIS G3131-2005
SPHC钢化学成分(质量分数)(%)
C:≤0.12
Mn:≤0.50
Si:≤0.30
S:≤0.040
P:≤0.035
SPHC钢力学性能
抗拉强度(σb/MPa):≥270
伸长率(δ5/%):≥33(钢材厚度或直径≤16mm),≥32(钢材厚度或直径16-40mm)
SPHC钢主要特性
具有高的塑性、韧性和焊接性能,良好的压力加工性能,但强度低。
SPHC钢应用举例
用于制造地脚螺栓、犁铧、烟筒、屋面板、铆钉、低碳钢丝、薄板、焊管、拉杆、吊钩、支架、焊接结构等。轧制薄板和盘条。冷、热轧薄钢板及以其为原板制成的镀锌、镀锡及塑料复合薄钢板大量用于屋面板、 装饰板、通用除尘管道、包装容器、铁桶、仪表壳、开关箱、防护罩、火车车厢等。盘条则多冷拔成低碳钢丝或经镀锌制成镀锌低碳钢丝,用于捆绑、张拉固定或用作钢丝网、铆钉等 。
