Alloy Steel
Has certain tenacity, sometimes require welding performance, used to make all kinds of engineering structures (such as building structures, Bridges, ships, vehicles, etc.) and manufacture all kinds of mechanical structure with steel.
With suitable hardenability, after appropriate metal heat treatment, the microstructure is homogeneous sorbite, bainite or very fine pearlite, thus has higher tensile strength and showed (generally at about 0.85), high toughness and fatigue strength, and low ductile to brittle transition temperature, can be used in the manufacture of large cross section size of the machine parts.
Meet certain level of strength and formability of steel. Formability expressed as a percentage elongation after interruption of tensile test. Structural steel is generally used for hosting purposes, in the purpose of sinosteel's strength is an important design criteria. Structural steels can be subdivided into: carbon structural steel low alloy steel and heat-resistant steel and alloy structural steel, and so on.
, less than 0.25% C for mild steel, notably the carbon is less than 0.10% of the 08 f, 08 al and so on, because has the very good deep drawing and welding is widely used for deep drawing parts such as automobile, can... Etc., 20 g is the main material to make ordinary boiler. In addition, low carbon steel as carburizing steel, widely used in machinery manufacturing.
• 0.25 ~ 0.60% C for medium carbon steel, used in the quenched and tempered condition more, make parts of the machinery manufacturing industry. How many 22 ~ 34 HRC, conditioning can get comprehensive mechanical properties, also easy to cut.
More than, greater than 0.6% C for high carbon steel, used in the manufacture of springs, gears, roll, etc., depending on the manganese content, and can be divided into ordinary manganese content (0.25 ~ 0.8%) and a high manganese content (0.7 ~ 1.0% and 0.9 ~ 1.2%) steel group. Manganese can improve the hardenability of steel, ferrite, improve the steel yield strength, tensile strength and abrasion resistance. Usually in high manganese steel grades after additional tags "Mn", such as 15 Mn, 20 Mn to distinguish it from normal carbon steel containing manganese content.
