結構鋼結構鋼是指符合特定強度和可成形性等級的鋼。可成形性以抗拉試驗中斷后伸長率表示。結構鋼一般用于承載等用途，在這些用途中鋼的強度是一個重要設計標準。結構鋼可以細分為：合金結構鋼、碳素結構鋼、低合金結構鋼、耐熱結構鋼等等。分類優(yōu)質(zhì)碳素結構鋼和普通碳素結構鋼相比，硫﹑磷及其它非金屬夾雜物的含量較低。根據(jù)含碳量和用途的不同，這類鋼大致又分為三類：1、 小于0.25%C為低碳鋼，其中尤以含碳低于0.10%的08F，08Al等，由于具有很好的深沖性和焊接性而被廣泛地用作深沖件如汽車﹑制罐......等，20G則是制造普通鍋爐的主要材料。此外，低碳鋼也廣泛地作為滲碳鋼，用于機械制造業(yè)。2、0.25～0.60%C為中碳鋼，多在調(diào)質(zhì)狀態(tài)下使用，制作機械制造工業(yè)的零件。調(diào)質(zhì)多少22~34HRC，能得到綜合機械性能，也便于切削。3、大于0.6%C為高碳鋼，多用于制造彈簧﹑齒輪﹑軋輥等，根據(jù)含錳量的不同，又可分為普通含錳量（0.25～0.8%）和較高含錳量（0.7～1.0%和0.9～1.2%）兩鋼組。錳能改善鋼的淬透性，強化鐵素體，提高鋼的屈服強度﹑抗拉強度和耐磨性。通常在含錳高的鋼的牌號后附加標記“Mn”，如15Mn﹑20Mn以區(qū)別于正常含錳量的碳素鋼。碳素工具鋼含碳量在0.65～1.35%之間，經(jīng)熱處理后可得到高硬度和高耐磨性，主要用于制造各種工具﹑刃具﹑模具和量具（見工具鋼）。
