P460NL1 Boiler Steel Composition Properties

P460NL1 steel plate is a type of steel used for boilers and pressure vessels, with excellent mechanical and corrosion resistance properties. P460NL1 boiler steel is widely used in fields such as boilers, pressure vessels, buildings, bridges, ships, and automobiles.

1. P460NL1 Ingredients

P460NL1 steel plate is a low alloy high-strength structural steel, mainly composed of elements such as carbon, silicon, manganese, phosphorus, sulfur, nitrogen, etc. Among them, carbon is one of the most important elements in steel, which can improve its strength and hardness, but also reduce its plasticity and toughness. Silicon and manganese are important alloying elements in steel, which can refine the microstructure of steel, improve its strength and hardness. Phosphorus and sulfur are harmful elements in steel, which increase its brittleness and reduce its toughness. Nitrogen is an element with solid solution strengthening and aging strengthening effects, which can improve the strength and hardness of steel.

2. P460NL1 Mechanical properties

P460NL1 boiler steel plate has excellent mechanical properties, with high indicators such as tensile strength, yield strength, elongation, and impact toughness. At room temperature, the tensile strength of P460NL1 steel plate is generally between 400-650MPa, the yield strength is generally between 270-400MPa, the elongation is generally between 18% -25%, and the impact toughness is generally between 80-100J/cm ² Between. At high temperatures, the mechanical properties of P460NL1 steel plate will be affected to some extent, but it can still maintain a high level.

3. P460NL1 process performance

P460NL1 steel plate has good process properties and can be used for various processing and forming operations. For example, it can produce parts and components of various shapes and sizes through cutting, bending, stamping, welding and other process operations. In addition, P460NL1 steel plate also has good weldability and processability, which can meet various welding and processing needs.

4. Corrosion resistance of P460NL1

P460NL1 steel plate has good corrosion resistance and can be used in various corrosive environments. For example, in a marine environment, P460NL1 steel plates can resist corrosion from seawater and marine atmosphere; in chemical environments, P460NL1 steel plates can resist corrosion from various chemical substances. P460NL1 steel plate also has good fatigue resistance and impact resistance, and can maintain stable performance under various complex stress conditions.
