What is the difference between 1018 and S355J2W corten steel steel?

The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating S355J2W corten steel production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.

The steel plate used for containers and pressure vessel has to bear different pressures and strengths due to the manufactured containers. The normal pressure is generally 31.4MPa or higher; the working temperature is usually between -20 ℃ -450 ℃, and sometimes lower than -20 ℃. According to the working conditions and processing technology of the container, the S355J2W corten steel, steel plate used for the container must have good cold bending and welding performance. Besides, it should have good plasticity and toughness, high temperature short-term strength or long-term strength performance.

Advantages of NM360 wear-resistant steel plate: NM360 steel has high strength: generally its yield strength is above 300MPa. 2. High toughness: The elongation is required to be 15% -20%, and the room temperature impact toughness is greater than 600kJ / m ~ 800kJ / m. For large welded components, high fracture toughness is also required. 3. NM360 steel plate has good welding performance and cold forming performance. 4. Low cold and brittle transition temperature.

The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of S355J2W corten steel nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of S355J2W corten steel steel, can be used as an alloying element of low alloy steel.

Hardness comparison between Q345B steel and NM450 steel: wear resistant steel for construction machinery requires high wear resistance, high toughness, impact resistance, easy welding, easy forming and other high-performance characteristics. The main index of wear resistance is the surface hardness. The higher the hardness, the better the wear resistance. Compared with S355J2W corten steel, Q345B steel, the hardness of NM450 steel is only increased 3 times, but the average service life is increased 6-8 times under the same working conditions.
