Docol 600LA is a high-strength low-alloy that provides the performance for modern, rapid production methods. Applications include components and parts of load bearing structures such as chassis.
Docol 600LA High Strength Low Alloy Steel (HSLA) Description
Docol 600LA HSLA has higher yield strength and tensile strength than other kinds of HSLA, giving it superior performance in withstanding impact and tensile stress. Besides, Docol 600LA HSLA steel has lower alloying element content, which is beneficial to the implementation of welding processes. Its good plasticity and malleability are conducive to the implementation of various forming processes and reduce manufacturing costs. In machinery manufacturing industry, Docol 600LA HSLA is commonly used to manufacture heavy machinery, construction machinery, petrochemical equipment, etc., to improve the efficiency and service life of the equipment. Besides, the steel is widely adopted in the field of energy engineering for nuclear power plants, thermal power plants, wind power generation, etc., to ensure the reliable operation of equipment.
