Introduction Structural Steel(SM520YB)
Structural steel is to point to a specific strength and formability of grades of steel.Formability expressed as a percentage elongation after interruption of tensile test.Structural steel, generally for hosting purposes, in the strength of these USES of sinosteel is an important design criteria.
Classification of Structural Steel
Structural steels can be subdivided into: alloy structural steel, carbon structural steel and low alloy steel, heat-resistant steel, and so on.
Compared to high quality carbon structural steel and ordinary carbon structural steel, sulfur, phosphorus and other non-metallic inclusion content is low.According to carbon content and purpose is different, this kind of steel is roughly divided into three categories:
1, less than 0.25% C for low carbon steel, notably the carbon less than 0.10% of the 08 f, 08 al and so on, because has the very good deep-drawing property and weldability and is widely used for deep drawing parts such as cars, can...Such as, 20 g is the main material of ordinary boiler.In addition, low carbon steel as carburizing steel, widely used in mechanical manufacturing industry.
More than 2, 0.25 ~ 0.60% C for medium carbon steel, used in the quenched and tempered state, making parts of machinery manufacturing industry.How many 22 ~ 34 HRC conditioning, gets the comprehensive mechanical properties, also facilitate cutting.
More than 3, more than 0.6% C for high carbon steel, used in the manufacture of springs, gears, roll, etc., according to different manganese content, and can be divided into ordinary manganese content (0.25 ~ 0.8%) and high manganese content (0.7 ~ 1.0% and 0.9 ~ 1.2%) steel group.Manganese can improve the hardenability of steel, strengthen the ferrite, improve the steel yield strength, tensile strength and abrasion resistance.Usually in the high manganese steel grades after additional tags "Mn", such as 15 Mn, 20 Mn to distinguish it from normal carbon steel containing manganese content.
Carbon tool steel carbon content between 0.65 ~ 1.35%, high hardness and high wear resistance can be obtained after heat treatment, mainly used in the manufacture of a variety of tools, cutting tool, mould and measuring tool.
