不锈钢材料理论重量计算方法

理论重量计算方法

角钢：每米重量=0.00785*（边宽边宽-边厚）*边厚

圆钢：每米重量=0.00617*直径*直径(螺纹钢和圆钢相同)

扁钢：每米重量=0.00785*厚度*边宽

管材：每米重量=0.02466*壁厚*（外径-壁厚）

板材：每米重量=7.85*厚度

黄铜管：每米重量=0.02670*壁厚*（外径-壁厚）

紫铜管：每米重量=0.02796*壁厚*（外径-壁厚）

铝花纹板：每平方米重量=2.96*厚度

有色金属比重：紫铜板8.9黄铜板8.5锌板7.2铅板11.37

有色金属板材的计算公式为：每平方米重量=比重*厚度

不锈钢各个材质的比重

1、304、304L、304J1、321、201、202比重7.93

2、316、316L、309S、310S比重7.98

3、400系列比重7.75

不锈钢管：（外径—壁厚）×壁厚×0.02491=Kg /m

不锈钢板；（长×宽）×厚×比重==Kg/平方厘米

圆钢：（直径×直径）0.00623=Kg /M

卷价: 平板价格*理论厚度/实际厚度-开平费

平板价: 卷价*实际厚度/理论厚度+开平费

理论计算公式：

卷板：过磅重量÷参厚（实际厚度）×理论厚度=理重

卷板开平板：长宽×宽度×厚度×密度=理重

中板：长度×宽度×理论厚度×密度=理重

卷长：实际重量÷宽度÷厚度（参厚）÷密度=卷长

卷的实际厚度：切边卷=卷重÷宽度÷卷长÷密度

毛边卷=（卷重—边丝重）÷宽度÷卷长÷密度平板价格：平板价格=（卷重*市场基价—边丝金额+开平费）/开平板总重

铝板比重：2.68g/㎝3
