What is the hardness of Q235C carbon steel plate sheet?

In the development process of more than 20 years, the company keeps pace with the times, keeps innovating its ideas, constantly adjusting its steel product Q235C carbon steel plate sheet structure, constantly strengthening its comprehensive competitiveness, constantly improving its management level, and more importantly, forming its corporate culture of elements and personality. The company always strives to build itself a comprehensive competitive steel Q235C carbon steel plate sheet supplier in the world.

GB711-2011 Chinese steel standard is used in the manufacture of steel plates with a Q235C carbon steel plate sheet thickness of not more than 150mm for navigating ships, fishing boats and marine engineering structures in ocean, coastal and inland waterway areas. CCS/NV/GL550 steel is a structural steel for ships and marine engineering, divided into four quality grades A, D, E, F, namely AH550, DH550, EH550, FH550, H is high-strength building materials, and 550 is the lower yield strength.

Our company provides Q235C carbon steel plate sheet, A302 gr. B boiler plate for customers all over the world, which is used for pressure vessels, boilers, tanks and heat exchangers in oil and gas projects. The boiler steel plate of ASTM A302 grade B /A302 gr. B can be rolled with a maximum thickness of 300 mm, and the steel performance, including mechanical properties and chemical composition, can be guaranteed to fully comply with ASTM A302 / A302M standard.

The steel such as Q235C carbon steel plate sheet delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.
