Cause analysis of slag hanging in S355J2WP material cutting process

We are a professional S355J2WP material steel raw material supplier with a history of 17 years. After years of development, the company's steel plates and coils are widely used in construction, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and other fields around the world. With good product S355J2WP material quality, we have solid project cooperation with foreign governments or leading enterprises such as Egypt, Bangladesh, Myanmar, Thailand, Philippines, Vietnam, Venezuela, Peru, Mexico, the United States, Portugal, Russia, Iran, Iraq, Pakistan, etc.

Steel is an alloy of iron with carbon, silicon, manganese, phosphorus, sulfur and a small amount of other elements. In addition to iron, carbon content plays an important role in the mechanical properties of S355J2WP material and so on steel. Iron and steel is an important raw material for machinery, construction, hardware and other industries. As an important pillar industry, the development of iron and steel has a glorious period, in which Tangshan was once an important production base of China's iron and steel. This is closely related to its geographical location and energy advantages.

The boiler steel is not only required to have good corrosion resistance at low temperature, but also required to have good oxidation resistance at high temperature for components working at high temperature. Especially for the components of superheater and reheater, when they S355J2WP material work at high temperature, they are required not easy to be oxidized and peeled. Generally, the development speed of oxidation depth at working temperature is required to be less than 0.1mm/year. The addition of chromium, nickel, aluminum and silicon can improve the oxidation resistance of steel.

The mechanical properties of S355J2WP material, boiler pressure components steel include strength, plasticity, toughness and fatigue properties. Temperature has a great influence on the mechanical properties of steel. With the increase of temperature, the yield limit of all kinds of steel will monotonically decrease, but the tensile strength will rise to a high peak at a certain temperature, and then decrease.

Our company supply various size and thickness S355J2WP material, hot rolled plates. Plate thickness is available ranging 3mm to 350mm. Steel coils thickness are supplied in max. 25mm. Tolerances for carbon steel coils for conversion to: For minimum gauge orders, thickness and width tolerances are in accordance with the respective ASTM specifications of A568 for thicknesses of less than 0.230 inches(exclusive), and A635 for thicknesses of 0.230 inches to 1.00 inch, inclusive.

We have our own factory, including the production and manufacturing of steel pipes, with a special S355J2WP material steel pipe manufacturer and storage warehouse. Welcome to visit our factory, we will provide customers with high quality products that meet the requirements. And has the perfect S355J2WP material after-sale service guarantee system, lets the customer save the worry and the labor.

The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the S355J2WP material principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
