1. Introduction to P460NH steel plate grade:
P460NH steel plate is a high-strength hot-rolled structural steel plate that complies with the European standard EN10028-3. where P represents the pressure vessel steel, 460 indicates the minimum yield strength of 460 MPa, and NH indicates that it is suitable for use in low-temperature stress environments.
2. The chemical composition of P460NH steel plate is as follows:
Carbon (c) content: 020%
Silicon (Si) content: 060%
Manganese (Mn) content: the maximum value is 110-1.70%
Phosphorus (P) content: 0025%
Sulfur (S) content: 0 maximum015%
Chromium (CR) content: 030%
Nickel (Ni) content: 080%
Copper (Cu) content: The maximum value is 070%
Niobium (NB) content: 005%
Vanadium (V) content: 020%
Aluminium (Al) content: 0020%
Titanium (Ti) content: The maximum value is 003%
Cesium (Re) content: 002%
Nitrogen (n) content: 0025%
3. Application of P460NH steel plate.
