熱軋型鋼 GB /T 706 - 2016

牌号 化學成分(質量分數%)

本标準适用範圍,牌号、化學成分及力學性能

1 [國标]
GB /T 1591 - 2018
低合金高強度結構鋼
High strength low alloy structural steels
2 [國标]
GB /T 700 - 2006
碳素結構鋼
Carbon Structural Steels

• 本标準适用于熱軋等邊角鋼、不等邊角鋼及腿内側有斜度的熱軋工字鋼和熱軋槽鋼。

• 鋼的牌号、化學成分、力學性能應符GB/T 700或GB/T 1591的相關規定。根據需方要求,經供需雙方協議,也可按其他牌号和化學成分供貨。

• 型鋼應按理論重量交貨,以密度為7.85g/cm3計算。經供需雙方協商并在合同中注明,也可按實際重量交貨。

• 重量允許偏差應不超過±5%。重量允許偏差适用于同一尺寸質量不超過1噸的一批,當一批同一尺寸的質量不大于1t但根數大于10根時也适用。

 重量偏差=(實際重量-理論重量)/理論重量×100%

• 規格表示方法:

工字鋼:“Ⅰ”與高度×腿寬×腰厚;如:Ⅰ450×150×11.5(簡記為Ⅰ45a)

槽鋼: “[”與高度×腿寬×腰厚;如:[ 200×75×9(簡記為[ 20b)

等邊角鋼:“∠”與邊寬×邊寬×邊厚;如:∠ 200×200×24(簡記為∠ 200×24)

不等邊角鋼:“∠”與長邊寬×短邊寬×邊厚;如:∠ 160×100×16

• 隻錄入工字鋼、槽鋼及部分等邊角鋼規格與截面圖,其他型鋼規格及截面圖見本标準原件。
