Q235 steel grades cover Q235A, Q235B, Q235C and Q235D. Other than Q235A, the other three Q235 steel grades needs impact test. Charpy V-notch specimen is used for impact toughness test. The impact toughness index is Akv. Q235 steel plates are widely used because of its moderate carbon content, good comprehensive performance, good coordination of strength, plasticity and welding performance.

Converter steelmaking: The furnace body of the converter can be rotated, and the steel plate is used as the outer shell, and the refractory is used as the inner lining. Converter A573 grade 70 structural steel plate steelmaking does not require additional heating, because the molten iron is inherently high temperature, and it still continues to generate thermal oxidation reactions (from silicon, carbon and oxygen in molten iron).Because no more fuel is needed for heating, energy consumption is reduced.
The company adheres to the management concept of "people-oriented, talent is concerned", develops business with the spirit of "believing strength, practical style, A573 grade 70 structural steel plate professional service and dare to compete", and provides customers with "professional, value-added and effective" service support. For the company's development and take-off, we work together to move forward and create a better A573 grade 70 structural steel plate tomorrow!
