H型鋼，是一種截面面積分配更加優(yōu)化、強(qiáng)重比更加合理的經(jīng)濟(jì)斷面型材，因其斷面與英文字母“H”相同而得名。H型鋼的兩條外邊內(nèi)側(cè)沒有斜度，是平直的。這使得H型鋼的焊接拼接比工字鋼操作簡(jiǎn)單，單位重量的力學(xué)性能更好，可以節(jié)省大量的材料和施工時(shí)間。

H steel is a more efficient and economical section with high section area distribution, because its section is the same as the English letter "H". The two sides of the H type steel have no slope inside the inner side, and they are straight. This makes the welding and splicing of H steel simpler than I-steel, better mechanical properties per unit weight, and can save a lot of material and ctruction time.

H型鋼的翼緣都是等厚度的，有軋制截面，也有由3塊板焊接組成的組合截面。工字鋼都是軋制截面，翼緣內(nèi)邊有1：10坡度。

Ｈ型鋼的軋制不同于普通工字鋼僅用一套水平軋輥，由于其翼緣較寬且無(wú)斜度(或斜度很小)，故須增設(shè)一組立式軋輥同時(shí)進(jìn)行輥軋。

The flange of the H steel is equal thickness, has a rolling cross section, and a  section of 3 plates. The I-steel is the rolling section, and the inner edge of the flange has the 1:10 gradient.

The rolling of H steel is different from ordinary I-beam only with a set of horizontal rolls. Because of its wide flange and no slope (or very small slope), a group of vertical rollers should be set up and rolled at the same time. 

隨著科學(xué)技術(shù)和工業(yè)的發(fā)展，對(duì)材料提出了更高的要求，如更高的強(qiáng)度，抗高溫、高壓、低溫，耐腐蝕、磨損以及其它特殊物理、化學(xué)性能的要求，碳鋼已不能完全滿足要求。

With the development of science and technology and industry, the material has put forward higher requirements, such as higher strength, high temperature, high pressure, low temperature, corrosion resistance, wear and other special physical and chemical properties, carbon steel can not fully meet the requirements.
