The clad steel plate is based on carbon structural steel, which is sprayed with stainless acid resistant and heat-resistant steel on the surface. The clad steel plate is widely used to make acid and alkali resistant container. Advantages of clad steel plate: The appearance of the clad steel plate is very smooth, the quality is very good, and it will not rust. Disadvantages of clad steel plate: the SMA490BW hot rolled structural steel grade, clad steel plate has better requirements for production technology and are more expensive.

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized SMA490BW hot rolled structural steel grade are higher than that of annealed SMA490BW hot rolled structural steel grade, but the elimination of internal stress is not as good as annealing. The normalizing operation of SMA490BW hot rolled structural steel grade is simple, the cost is low, the productivity is high, and it is widely used in actual production.

In 2018, one of our India customers visit Zhengzhou office building and work shop to discuss carbon steel Q235B grind plate technical request. They have strict surface and thickness tolerance, and they also request UT and MT for testing for Q235B grind plate. As a result, they purchase 179 tons as trial order for first cooperation. After using the gind plate, the India customer has good comment on our SMA490BW hot rolled structural steel grade quality. Till now, we keep exporting around 100 tons per month as regularly.
