As the basic processing materials and building materials, the medium and heavy plate is an important purchasing material for many manufacturers and construction enterprises, so the grasp of the latest price rise and fall of the medium and heavy plate, q345r equivalent material is directly related to the cost and profit of enterprises. Therefore, it is necessary for purchasing staff to learn how to predict. Today, we share the latest price rise and fall skills, how to predict the price trend of medium and heavy plate, q345r equivalent material.

Good impact resistance. Wear resistant composite steel plate uses low carbon steel or low alloy, stainless steel and other toughness as the base material. The q345r equivalent material metal material not only has good wear resistance, but also can withstand the impact and wear of falling from high to low in the transportation process. It has good heat resistance. Vanadium, molybdenum and other q345r equivalent material alloy materials are added into the alloy wear-resistant layer during the manufacturing process, so it can be used and worn at high temperature ≤ 800 ℃. Compared with ordinary q345r equivalent material carbon steel substrate, it can only be used below 380 ℃, while low alloy heat-resistant steel plate can work below 540 ℃. This shows how high the heat resistance coefficient of wear-resistant steel plate is. Good corrosion resistance.

In order to improve the q345r equivalent material corrosion resistance and decoration of steel, it is an important content of steel production method to plating or coating a protective layer on the surface of plastic processed steel. The material of protective layer is divided into metal and non-metal. The metal protective layer adopts the methods of electroplating, hot plating and chemical plating. The main q345r equivalent material coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking q345r equivalent material sheet metal as an example, there are many hot-dip galvanizing methods used in sheet metal galvanizing. Continuous hot-dip galvanizing is one of the main galvanizing methods used in the world.
