Zinc plated EN 10025-6 grade S690QL plates

Because 15CrMo steel contains high content of Cr, C and other alloying elements, the hardening tendency of steel is obvious and the weldability is poor. 15CrMo steel plate is used in petroleum, petrochemical, high-pressure boilers, etc., seamless pipes for special purposes include seamless pipes for boilers, seamless steel pipes for geology, seamless pipes for petroleum, etc. Welcome to contact us for EN 10025-6 grade S690QL plates product price in 2020.

The company is a leading company that sells EN 10025-6 grade S690QL plates steel plate products in the Central Plains region and has a high reputation in the steel plate industry.

In order to improve the EN 10025-6 grade S690QL plates 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 EN 10025-6 grade S690QL plates coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking EN 10025-6 grade S690QL plates 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.

The characteristic of niobium in EN 10025-6 grade S690QL plates etc. steel material is to increase the recrystallization temperature of austenite, so as to achieve the purpose of refining austenite grains. In general, the amount of niobium added in steel material is less than 0.05%, and the contribution of niobium above 0.05% to strengthening and toughening will no longer be obvious.
