高強(qiáng)鋼板（高強(qiáng)板）是指牌號(hào)Q460鋼，強(qiáng)度高，特別是在正火或正火加回火狀態(tài)有較高的綜合力學(xué)性能。主要用于大型船舶，橋梁，電站設(shè)備，中、青海西寧附近高壓鍋爐，高壓容器，機(jī)車車輛，起重機(jī)械，礦山機(jī)械及其他大型焊接結(jié)構(gòu)件Q460是一種高強(qiáng)度的低合金鋼。Q460的牌號(hào)表示方法：它的鋼號(hào)冠以“Q”，代表鋼材的屈服點(diǎn)，即屈服強(qiáng)度。后面的數(shù)字表示屈服點(diǎn)數(shù)值460代表460兆帕，兆是10的6次方，帕是壓強(qiáng)單位帕斯卡。Q460就是鋼材受力強(qiáng)度達(dá)到460兆帕?xí)r才會(huì)發(fā)生塑性變形，也就是當(dāng)外力泄掉后，鋼材只能保持受力的形狀而無法回復(fù)原形，這個(gè)強(qiáng)度要比一般鋼材大。一般質(zhì)量等級(jí)符號(hào)分別為A、青海西寧附近B、青海西寧附近C、青海西寧附近D、青海西寧附近E　Q460在保證低碳當(dāng)量的基礎(chǔ)上，適當(dāng)?shù)脑黾恿宋⒑辖鹪氐暮?。良好的焊接性能要求鋼材碳?dāng)量低，而微合金元素的增加在增加鋼材強(qiáng)度的同時(shí)，也會(huì)增加鋼材的碳當(dāng)量。但好在增加的碳當(dāng)量很少，所以不會(huì)影響鋼材的焊接性能。
