NM550 Steel Plate

NM550 steel is a high-strength wear-resistant steel plate with high wear resistance. The Brinell hardness value of 500 (HBW) is mainly used to protect the occasion or part where wear is required, so that the equipment can last longer and reduce the maintenance. Overhaul and downtime, correspondingly reduce the investment of funds.

The rolling characteristics of NM550 wear-resistant steel plate are characterized by various size specifications and widening rolling required for rolling.

Firstly, Raw materials are tested then it will go for production. These are fabricated from top class rolling mills. In addition, tempering and annealing process refines ingot structure of plates as that it gain sturdy finish. These plates have a robust design because different surface finishing process is conducted. One can choose the finishing process from the following list- matte finish, BA finish, hairline, sand brushing, and NO1 finish, SATIN met with plastic coat and polished with the bright black coat. These coatings prevent oxidation and rusting around the corrosive environments.

Generally, plates have a uniform structure but to find the reliability of product manufactures conduct testing. Mostly IGC test, positive material test, mechanical test, hardness test, chemical test, pitting resistance test are performed. However, clients can demand any specific test as per their requirement. Additionally, third parties accomplish final inspection on NM450 steel plates for 100% quality assurance.

Heat treatment: quenching and tempering (quenching and tempering).
