Material Application
a. Quenched and tempered structural steel: The carbon content of this type of steel is generally about 0.25% to 0.55%. For structural parts of a given cross-sectional size, when quenched and tempered
along the cross-section during quenching and tempering (quenching and tempering), the mechanics
The performance is good. If the hardening is not penetrated and free ferrite appears in the microstructure, the toughness decreases. For steels with a tendency to temper brittleness,
such as manganese steel, chromium steel, nickel-chromium steel, etc., they should be cooled quickly
after tempering. The quenching critical diameter of this type of steel increases with the increase in grain size and alloying element content. For example, 40Cr and 35SiMn steel are about 30-40mm,
and 40CrNiMo and 30CrNi2MoV steel is about 60-100mm, which is often used in manufacturing Structural
parts such as shafts and connecting rods with large loads.
