GTML26-M/GTML35-M Cold Heading Steel Hot-rolled Coils

In terms of chemical composition, ML26 has a carbon content ranging from 0.23% to 0.29%, a silicon content from 0.15% to 0.35%, and a manganese content from 0.60% to 0.90%. GTML26 - M may have similarities in chemical composition, containing appropriate amounts of elements such as carbon, silicon, and manganese to ensure it has good cold - heading performance and a good combination of strength and toughness. In terms of performance, ML26 has good cold - heading performance and a good combination of strength and toughness. After appropriate heat treatment, it can obtain relatively high strength and hardness while maintaining a certain degree of toughness and plasticity. GTML26 - M may also have good cold - heading performance, being able to be processed into fasteners or other parts of various shapes through the cold - heading process at room temperature, and having good comprehensive mechanical properties to meet the requirements under different usage conditions.

Characteristics of GTML26 - M/GTML35 - M cold - heading steel hot - rolled coils:

Good cold - heading performance: As cold - heading steel, it should have excellent cold - heading performance, being able to withstand large plastic deformations at room temperature without defects such as cracks, so as to be easily processed into fasteners or other cold - heading parts of various shapes.

Balance between strength and toughness: It has appropriate strength and a good combination of toughness. After appropriate heat treatment, it can obtain relatively high strength and hardness while maintaining a certain degree of toughness and plasticity to meet the mechanical property requirements under different usage conditions, such as withstanding various loads in industries like automotive and machinery manufacturing.

High requirement for surface quality: Generally speaking, cold - heading steel hot - rolled coils have strict requirements for surface quality. The surface should be smooth and free of defects such as cracks, folds, and scars to avoid problems such as cracking caused by surface defects during the cold - heading process, which may affect the quality and performance of the product.

GTML26 - M/GTML35 - M cold - heading steel hot - rolled coils are mainly used for manufacturing medium - strength fasteners, such as bolts, nuts, and screws, and are widely used in industries such as automotive, machinery manufacturing, and construction.
