S355J2W(H) weather-resistant steel plate
Standard description: European standard structural steel hot-rolled steel plates and strips
355: Specified maximum yield strength, MPa. As the thickness increases, the yield guarantee value decreases.
J2: Impact power level, -20 degree impact power ** value 27J
The main components of S355J2W steel plate are iron, carbon, manganese, phosphorus and other elements. The carbon content is low and the alloying element content is moderate. It has good comprehensive mechanical properties and welding performance. Specifically, S355J2W steel plate has the following characteristics:
1. High strength: S355J2W steel plate has high yield strength and tensile strength, can withstand large loads and has high safety performance.
2. Good plasticity: S355J2W steel plate has good plasticity at high temperatures and can undergo a certain degree of deformation processing, such as bending, curling, etc.
3. Good welding performance: S355J2W steel plate contains an appropriate amount of alloy elements and has good welding performance. The welded joint has high strength and good compactness.
4. Good corrosion resistance: After special treatment, S355J2W steel plate has good corrosion resistance and can be used in harsh environmental conditions.
