Which is better, carbon steel or JIS carbon steel SM400A CS plate?

Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, JIS carbon steel SM400A CS plate based on a high starting point and high technology, the company has vigorously developed various steel products JIS carbon steel SM400A CS plate and deep-processed parts, steel structures, precision castings, seamless pipes.

EN10025-3 S460N high-strength steel has high strength, especially in normalizing or normalizing and tempering state. It has higher comprehensive mechanical properties. S460N plates are mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. S460N mechanical properties: tensile strength Rm500-680MPa, yield strength: 420-320MPa, elongation after fracture 18-19%.

The steel plate for hull structure is also called marine plate or shipbuilding steel. Due to the harsh working environment of the ship, the hull shell is subject to the chemical corrosion of seawater, so the requirements for steel for the hull structure are strict. First of all, good toughness for marine plate JIS carbon steel SM400A CS plateis the most critical requirement. In addition, it requires higher strength, good corrosion resistance, welding performance, processing performance and surface quality.

As the tungsten content increases, the strength and toughness of the NM360 wear-resistant steel plate increase. When the mass fraction of tungsten exceeds 1.06%, the toughness decreases due to the increase in the amount of carbide precipitation. This is because tungsten combines with carbon atoms in the NM360 wear-resistant plate to form a short-range ordered C-w atom pair bond structure. The C-w atomic bond is stronger than the C-Mn and C-Fe atomic bonds. Therefore, after adding tungsten to the NM360 wear-resistant steel plate, cracks will be formed, and the energy required to break the atomic bond will be greatly increased. The toughness and strength of JIS carbon steel SM400A CS plate, NM360 wear-resistant steel plate treated with water toughening treatment will also be significantly improved.

JIS carbon steel SM400A CS plate, 35CrMo alloy steel is Chinese structual steel. As specified in GBT3077 standard, 35CrMo steel chemical composition should be: Carbon content 0.32-0.40 (C), Silicon content 0.17-0.37 (Si), Manganese content 0.40-0.70 (Mn), Chrome content 0.80-1.10 (Cr), Molybdenum content 0.15-0.25 (Mo). The heating temperature for 35CrMo alloy steel quenching is 850 Centigrade, the cooling material is oil. The heating temperature for 35CrMo alloy steel tempering is 550 Centigrade, the cooling material is oil or water.
