NP550 steel plate mechanical performance and characteristics

1. The same series of NP550 steel include NP370, NP450, NP500, etc.

2. NP550 steel plate is based on the rare high-hardness and ultra-high-hardness special protective steel in China, and has developed a thin steel plate with high anti-elasticity, high strength and resistance, and excellent process performance. NP550 material can resist high speed infringement.

3. Properties indicators of NP550 steel plate:
Mechanical properties: strength, hardness, plasticity, fatigue, impact resistance.
Chemical properties: corrosion resistance, high temperature oxidation.
Physical properties: density, melting point, thermal expansion, magnetism, electrical conductivity.
Process performance: cutting performance, forgeability, castability, weldability.

4. NP550 steel plate mechanical properties:
Use V, Ti or Nb microalloyed Cr-Ni-Mo or Cr-Ni medium-carbon low-alloy steels, through vacuum training + electroslag remelting, etc. to advance the purity, refine the grains, and improve the durability and process performance such as formability, through heat treatment to achieve high performance.

5. Safety protection steel plate NP550 has strong resistance to destructive impact, uniform and stable performance, good shape and surface quality. It is usually supplied in controlled rolling, quenching, quenching and tempering condition.
