Why is water seeping out of the slit when cutting EN10025-4 S355M steel

BEBON has been engaged in the piping industry as a professional manufacturer and supplier of steel plates, ship plates, corten steel, pressure vessels, EN10025-4 S355M steel steel pipelines, seamless pipe and ERW pipes since the inception. We provide integrated solutions to whole-package procurement covering miscellaneous ferrous and non-ferrous piping components. The products are widely used in oil & gas project, subsea or offshore platform piping, EN10025-4 S355M steel chemical & pharmaceutical pipeline, power plant, sewage treatment, water supply piping, heat exchange application.

ABS AH36 ship steel plate is a structural steel with high strength for hull. Shipbuilding steel generally refers to the steel used for hull structure, which refers to the steel used to make the hull structure produced in accordance with the requirements of the classification society. This kind of product is often ordered, scheduled, and sold as special steel, ship steel plates, section steel, EN10025-4 S355M steel, angle steel bars, bulb flats.

The most remarkable characteristic of low alloy high strength steel is high strength. In hot rolling or normalizing state, the strength of low alloy high strength steel is generally 30% - 50% higher than that of corresponding carbon engineering structural steel, EN10025-4 S355M steel. Therefore, it can bear large load. Engineering structures are usually large or huge, and the weight of the component itself often becomes an important part of the load. When the strength of the structural material is improved, the self weight of the component can be significantly reduced, and its ability to bear other loads can be further improved.

For EN10025-4 S355M steel, wear-resistant plate, the change of temperature in production and processing will directly affect the properties of the whole plate, so the effect of isothermal treatment of wear-resistant steel plate has been studied all the time. The results show that the continuous cooling transformation curve, microstructure, phase and similar structural phase of wear-resistant plate also change under different heating temperature.

Composition of low alloy steel plate: Low carbon: due to the high requirements for toughness, weldability and cold formability of low alloy steel plate, the carbon content is not more than 0.20%; manganese is added; the auxiliary elements such as niobium, titanium or vanadium are added; a small amount of niobium, titanium or vanadium forms fine carbide or carbonitride in the steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of low alloy steel plate; in addition, The corrosion resistance of EN10025-4 S355M steel, low alloy steel plate can be improved by adding a small amount of copper (< 0.4%) and phosphorus (about 0.1%).
