hardox 450 vs ar400 20mm plate stock in Kuala Lumpur
The XAR500 is a special structural steel with high wear resistance. This wearable special-purpose structural steel has an average hardness of 500 HB, high hardness and good toughness, and the structure made of the steel is stronger, lighter and can withstand impact load. Uses for Hardox 450 vs ar400 wear and tear - exposed structures such as shovels, shields for mining machines and bulldozers, shell walls, supports and stiffener, pavers and agricultural machinery.
In order to improve the Hardox 450 vs ar400 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.
Normalizing is a heat treatment that improves the toughness of steel. After the steel components are heated to 30-50°C above the Ac3 temperature, they are kept for a period of time and then air cooled. The main feature is that the cooling rate is faster than annealing but lower than quenching. During normalizing, the crystal grains of the steel Hardox 450 vs ar400 can be refined in a slightly faster cooling. Not only can satisfactory strength be obtained, but also the toughness (AKV value) can be significantly improved and reduced The tendency of the component to crack.
Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of Hardox 450 vs ar400 etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in Hardox 450 vs ar400 etc. steel is strictly controlled.
