Definition of alloy structural steel
Alloy structural steel is developed on the basis of non-alloy steel (carbon steel) by adding one or several alloying elements in appropriate amounts. The total alloy content in the steel is not large. , except for a few steel types that are between ~ (mass fraction), they generally do not exceed. According to its carbon content, it belongs to the category of hypoeutectoid steel. Alloy structural steel is mainly used to manufacture various mechanical parts that bear high stress and has a wide range of uses.
The changes in the mechanical properties of alloy structural steel, from the perspective of strength indicators, develop from lower strength to higher strength, high strength, and ultra-high strength. In this development process, the focus is on solving the problems of reduced plasticity and toughness caused by increased strength. The goal is always to pursue high comprehensive mechanical properties.
Classification of alloy structural steel On the premise of meeting the basic technical characteristics of alloy structural steel, based on the process characteristics of steel strengthening heat treatment or its composition, process and performance characteristics, alloy structural steel can be broadly divided into quenched and tempered steel, permeated steel Carbon steel, nitrided steel (nitrided steel), spring steel, bearing steel, cold heading steel, heat-resistant structural steel, non-quenched and tempered steel, free-cutting steel, boron steel, ultra-high-strength steel, etc. In view of the characteristics of spring steel, bearing steel, free-cutting steel, and ultra-high-strength steel, it is customary to separate them and classify them separately.
