Iron (Fe): Margin.
Carbon(c): 020%
Silicon (Si): 060%
Manganese (mn): 170%
Phosphorus (p): 0025%
Sulfur (s): 0015%
Chromium (cr): 030%
Nickel (Ni): 080%
Molybdenum (Mo): 020%
2. Mechanical properties.
P460NL1 steel plate has high strength and good toughness, and the specific mechanical properties are as follows:
Tensile strength: 570-720 MPa
Yield strength: 460 MPa
Elongation: 17%.
Section shrinkage: 40%.
Impact toughness (-50): 27 J
P460NL1 steel has the characteristics of high strength, high toughness, good fatigue resistance and impact resistance. Its yield strength is more than 460MPa, and the tensile strength is even higher. At the same time, P460NL1 steel also has good low-temperature toughness, which can maintain good mechanical properties at lower temperatures. These excellent mechanical properties make P460NL1 steel widely used in heavy machinery, bridges, construction, and other fields.
3. The implementation standard of P460NL1.
The implementation standard of P460NL1 is EN10028-3
Fourth, the delivery status of P460NL1.
P460NL1 is usually delivered in normalized condition, but it can also be normalized rolled instead of normalized according to user needs.
5. Welding performance of P460NL1.
P460NL1 steel has good welding properties and can be joined by a variety of welding methods, such as manual arc welding, submerged arc welding, gas shielded welding, etc. During the welding process, P460NL1 steel can maintain good toughness and plasticity, and is not prone to defects such as cracks. At the same time, its weld metal also has high strength and toughness, which can meet the requirements of engineering structure for connection strength.
