NM450 steel plates are abrasion resistance plate with great hardness. These are highly demanded in the fabrication industries. When imposed on reducing environments due to its resistant property these are prominent for reducing environments. These steel plates offer good weldability. These plates have an excellent finish which offers outstanding performance in oxidizing environments. The grade is blended with good resistance property towards corrosion. This serves high performance in reducing environments even at high temperatures. The grade is both magnetic and non-magnetic in nature. Steel plates resist distortion in terms of impact loading when the temperature gets higher.
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.
