Austria Exports A131 grade B steel wide flats

This European Standard EN 10225 specifies requirements for weldable structural steels to be used in the fabrication of fixed offshore structures in the form of plates A131 grade B steel wide flats up to and including 150 mm thick. It also specifies sections up to 63 mm thick except for sections delivered in the as-rolled condition which are permitted up to 25 mm thick only.

Established in 2014, Steel Safety Day was set up to reinforce awareness of the five most common causes of safety incidents and to create a safer working environment across the entire steel industry worldwide. By focusing every year on the five causes - moving machinery, working at heights, falling objects, on-site traffic and A131 grade B steel wide flats process safety incidents - worldsteel intends to set up a continuous improvement process and reiterate its commitment to the safety and health of the people who work in the A131 grade B steel wide flats industry.

Hot rolling and cold rolling are all the processes of forming steel plates or profiles, which have a great influence on the structure and properties of steel. The rolling of steel is mainly hot rolling, and cold rolling is usually used to produce small size steel and thin plate. With the development of new technologies such as the precision of hot rolling size, shape and surface quality and the continuous emergence of new products, A131 grade B steel wide flats, hot rolled steel strip and steel plate are widely used and have more and more competitive strength in the market.

The main function of boron in A131 grade B steel wide flats and so on steel is to increase the hardenability of steel, so as to save other rare and precious metals, such as nickel, chromium and molybdenum. For this purpose, the boron content is generally regulated in the range of 0.001% - 0.005%. It can replace 1.6% nickel, 0.3% chromium or 0.2% molybdenum. It should be noted that molybdenum can prevent or reduce temper brittleness, while boron slightly promotes temper brittleness, so molybdenum can not be completely replaced by boron.
