Structural Steels and Their Properties

Structural steels are called structural steels, which do not contain alloying elements with low carbon content and contain manganese, silicon, copper and sulfur elements, especially phosphorus and nitrogen, originating from production raw materials and production management, and are used in industrial and structural applications, taking into account the tensile strength of hot-formed and sometimes cold-drawn steels. is given the name. Structural steels, one of the preferred building materials in the construction industry, are materials with predictable behavior. Structural steels are classified into subgroups as hot formed, cold drawn, normalized, fine grained weldable, corrosion resistance improved, quenched high current resistant steels. Structural steels are one of the most used materials in the world with low carbon content. High strength low alloy steels are produced with varying strengths and low temperature toughness properties by controlling and directing the grain size. An important feature of structural steels is flexibility. Manufacturing methods applied to these steels; cutting, machining, cold and hot deformation and welding.

Structural Steel Properties

The properties of structural steels can be listed as follows; Suitable impact resistance Suitable yield limit and tensile strength Resistance to brittle fractures Easy weldability Easy formability Easy machinability Structural steels are generally shaped by hot rolling or forging after production. Defects such as scratches, burrs and cracks that occur during the applied shaping process must be properly removed. Structural steels should not be brittle in heat or cold. In machining of structural steels, normally annealed or cold-formed materials should be preferred. Heat treatment is not applied to structural steels other than normal annealing and stress relief annealing at temperatures of approximately 600°, 650°.
