20CrMnTi high-quality alloy structural steel is a high-performance alloy structural steel. This steel is widely used in many fields such as automobile manufacturing, aerospace, automobile manufacturing, petrochemical industry, etc., and has become the first choice material for manufacturing key parts.

Physical properties of 20CrMnTi high-quality alloy structural steel:

Tensile strength: ≥1080MPa, able to withstand larger loads.

Yield strength: ≥835MPa, ensuring the stability of the material when subjected to stress.

Elongation: ≥10%, indicating that the material has good plasticity.

Reduction of area: ≥45%, reflecting the deformation ability of the material before fracture.

Impact toughness: ≥69J/cm², ensuring the material’s ability to resist fracture when impacted.

20CrMnTi high-quality alloy structural steel heat treatment methods:

Normalizing: eliminates residual stress inside the material, refines the grains, and improves the cutting performance of the material.

Quenching: Heating a material above a critical temperature and then cooling it rapidly gives the material high hardness and strength.

Tempering: Heating to a certain temperature and keeping warm for a period of time, and then cooling slowly to eliminate quenching stress and improve the toughness and stability of the material.

During the heat treatment process, parameters such as heating temperature, holding time and cooling rate need to be strictly controlled to ensure that 20CrMnTi obtains the ideal performance.

As a high-performance alloy structural steel, 20CrMnTi has demonstrated its unique advantages in many fields. Whether in the fields of automobile manufacturing, machinery manufacturing, or aerospace, new energy equipment and mold industries, 20CrMnTi will continue to play an important role and provide strong support for the development of related industries.
