High yield strength SA514 grade Q steel material properties

The quality inspection department is responsible for the inspection management of raw materials and finished products, and the quality inspection and acceptance of products and raw materials. Strictly abide by the company's management system, conscientiously exercise the management power given by the company, and put an end to all ultra vires; be responsible for the inspection of all kinds of raw materials entering the company, and put forward quality problems and handling opinions.

Normalizing is a heat treatment that improves the toughness of steel. After the steel components are heated to 30-50°C above the Ac3 temperature, they are kept for a period of time and then air cooled. The main feature is that the cooling rate is faster than annealing but lower than quenching. During normalizing, the crystal grains of the steel SA514 grade Q steel material can be refined in a slightly faster cooling. Not only can satisfactory strength be obtained, but also the toughness (AKV value) can be significantly improved and reduced The tendency of the component to crack.

Weather resistant steel, as a new generation of advanced steel materials, has atmospheric corrosion resistance 2 to 5 times that of ordinary carbon steel. The longer it is used, the more prominent the corrosion resistance. Because it has the characteristics of rust resistance, no coating, thinning and consumption reduction, labor saving and energy saving, weather resistant steel can be applied to steel structures used in buildings, vehicles, bridges, towers and other long-term exposure to the atmosphere, SA514 grade Q steel material and can also be used to manufacture containers and railway Structural components such as vehicles, oil derricks, seaport buildings, and oil platforms.

How to distinguish between hot rolled and cold rolled process?The hot-rolled steel sheet has low strength, easy production and processing, and good plasticity. The process performance of the hot-rolled steel plate is poor (air oxidation and low smoothness), but the plastic deformation is good. Generally, it is medium and thick plate, SA514 grade Q steel material, high compressive strength, high strength, and high surface smoothness. Cold-rolled steel sheets have high strength and relatively difficult production and processing, but they are not easy to deform and have high compressive strength.
