槽钢属建造用和机械用碳素结构钢，是复杂断面的型钢钢材，其断面形状为凹槽形。 角钢可按结构的不同需要组成各种不同的受力构件，也可作构件之间的连接件。在加工行业中， 角钢耐高温明显的表现就是由于它的耐高温和耐火性能比较好，在很多的领域中可以发挥出了积极的作用。 角钢经高温油淬560～650℃回火后的组织均为回火索氏体+片状或块状铁素体+碳化物，也因此具有优良的强韧性。 随着回火温度升高，角钢的抗拉强度、屈服强度、硬度逐渐下降，冲击吸收能逐渐升高。综合考虑材料的强度与塑性， 620℃为角铁作为矿用大直径特种钻具材料的适宜回火温度。广泛地用于各种建筑结构和工程结构，如房梁、桥梁、输电塔、 起重运输机械、船舶、工业炉、反应塔、容器架以及仓库货架等，另外也常用来保护柱、挡墙等易撞部位。 Srough steel belongs to the construction and mechanical carbon structure steel, is a complex section of the type steel steel, its section shape is a groove shape.Angle steel can be composed of different stressed components according to the different needs of the structure, and can also be used as a connection part between the components.In the processing industry, the corner steel high temperature resistance is obvious performance because of its high temperature resistance and fire resistance performance is better, in many fields can play a positive role.The tissue of Angle steel tempered by 560~650℃ after high temperature oil is tempered Sortenite + sheet or massive ferrite + carbide, so it has excellent strong toughness.With the tempering temperature increasing, the tensile strength, yield strength and hardness of angle steel gradually decrease, and the shock absorption energy gradually increases. Considering the strength and plasticity of the material, 620℃ is the suitable tempering temperature of angle iron as a large diameter special drilling tool material. Widely used in a variety of building structures and engineering structures, such as beams, Bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container shelves and warehouse shelves, but also commonly used to protect columns, retaining walls and other easy to collision parts.
