The cold working performance of A514 Gr B quenched and tempered steel and so on steel structure engineering steel is good, which can ensure that the steel will not crack or brittle fracture during high-temperature processing, and will not have a great impact on strength, plasticity and toughness due to processing. The durability of A514 Gr B quenched and tempered steel and so on steel structure engineering steel is good. Durability refers to the service life of steel structure. The main factor affecting the service life of steel is the poor corrosion resistance of steel, followed by the deterioration of mechanical properties of steel under long-term load, repeated load and dynamic load.
The mechanical properties of hot rolled steel plate are far less than that of cold working and forging, but the A514 Gr B quenched and tempered steel, hot rolled steel plates have better toughness and ductility. Cold rolled steel plate has a certain degree of work hardening and toughness is low, but it can achieve a better yield ratio, and can be used for cold bending spring leaf and other parts. At the same time, because the yield point of cold rolled steel plate is close to the tensile strength, the danger is not foreseen in the use process, and accidents are prone to occur when the load exceeds the allowable load.
BBNsteel is one of the world-leading suppliers of construction steels for a global industry. We understand the unique demands of A514 Gr B quenched and tempered steel building large scale structures in an increasingly budget-conscious economy. Construction steel plates and steel sections are used from the ground up; particularly in civil engineering and large-scale industrial projects. Pilings and baffles are used to lay the groundwork and establish a strong foundational anchor for tall structures like skyscrapers.
BBN employees work hard and work hard in their work. In life, colleagues care about each other, like a family, and accompany each other at important moments in life. BBN Steel organizes employees to carry out tourism activities every year, so that families can be exposed to nature and relax physically and mentally. The good combination of working and rest can achieve the goal of hard work and happy life.
