Why is water seeping out of the slit when cutting S460ML steel

The S460ML steel plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The S460ML steel products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.

SM490A steel plate is a low-alloy high-strength steel. It is a structural steel produced in accordance with Japanese standard JIS G3106. Its strength σb is 490MPa. It is mainly used for buildings, bridges, ships, rail vehicles, petroleum storage tanks, containers and other buildings that require advanced weldability. S460ML steel, JIS SM490A steel sheet delivery status: steel plates with a thickness of <80mm, the delivery state is hot-rolled; steel plates with a thickness of ≥80mm, the delivery state is normalized condition.

The clad steel plate is based on carbon structural steel, which is sprayed with stainless acid resistant and heat-resistant steel on the surface. The clad steel plate is widely used to make acid and alkali resistant container. Advantages of clad steel plate: The appearance of the clad steel plate is very smooth, the quality is very good, and it will not rust. Disadvantages of clad steel plate: the S460ML steel, clad steel plate has better requirements for production technology and are more expensive.

The composition characteristics of low alloy high strength steel are low carbon ≤0.20%, low alloy, and total alloying elements is less than 3%. The low carbon content is to meet the process performance requirements of S460ML steel, low alloy high strength steel for engineering structural parts such as plasticity, toughness, weldability and cold deformation; adding a small amount of alloying elements (mainly Mn) to achieve the purpose of improving mechanical properties. Mn not only has a significant strengthening effect on ferrite, it can also reduce the cold brittle temperature of steel, increase the amount of pearlite in the steel, and further improve the strength.

S355J2+N steel plate belongs to the European standard low alloy structural steel grade. S355J2 steel is equivalent to Q345D grade. S460ML steel, S355J2+N low alloy steel plate is widely used in bridges, vehicles, ships, building steel structures. Mechanical properties of S355J2+N steel: Yield strength: ≤16mm: ≥355; 16-40: ≥345; 40-63: ≥335; 63-80: ≥325;80-100: ≥315; 100-150: 295; 150-200: ≥285; 200-250: ≥275; 250-400: ≥265. Tensile strength: 450-680MPa.
