P460NH steel is a normalized weldable fine grain steel. Executive standard: EN10028-3, steel number: 1.8935. P460NH steel is alloy special steel for GL-EH 40 higher strength steel pressure equipment. P460NH steel has good plasticity, toughness, cold bending performance and welding performance. P460NH steel plates are usually delivered in normalized condition. According to the negotiation between the supplier and the buyer, normalizing rolling can be used instead of normalizing. In this case, the sample shall be subject to simulated normalizing according to the agreed test frequency to verify that the performance meets the requirements.
The advantages of GL-EH 40 higher strength steel, carbon steel: First of all, the price of carbon steel is low. Compared with stainless steel, galvanized steel, alloy steel, etc., the carbon steel has a great advantage in price. It is a good choice for manufacturers and merchants such as construction sites that use building materials in large quantities. Secondly, the carbon steel is easy to process. In the early days, steelmaking technology was underdeveloped. It was very difficult to manufacture high-precision steel, and carbon steel is widely used.
If the chromium content in GL-EH 40 higher strength steel alloy steel reaches about 12%, dense chromium oxides will be formed on the surface of the steel, which will greatly improve the corrosion resistance of steel in oxidizing media. Chromium, aluminum, silicon and other elements can improve the oxidation resistance of steel and the corrosion resistance of high-temperature gas, but excessive aluminum and silicon will deteriorate the thermoplasticity of steel.
