2 inch EN steel grade S355J2 material heavy plate spot

20# steel plate is a high-quality low-carbon carbon steel plate, cold extruded, carburized and hardened steel. EN steel grade S355J2 material, 20# steel has low strength, good toughness, plasticity and weldability. The tensile strength is 253-500MPa, and the elongation is ≥24%. 20# steel performance is basically similar to 15# steel, but the strength is slightly higher.The cold-drawing or normalizing state of the cutting process is better than the annealing state. 20# steel is used to manufacture various mechanical parts with high toughness under hot rolling or normalizing state, which require high toughness.

Since its establishment, the company has adhered to the business philosophy of "integrity management, reputation first, mutual benefit", and adheres to the training principles of integrity, innovation and pioneering for its employees. It has long been dedicated to EN steel grade S355J2 material steel structure, shipbuilding, boiler vessel manufacturing, machinery manufacturing.

Product concept: take the technology leading as the pillar of the enterprise, achieve the development goal of the enterprise with the reliable products, the reliable technology and the trustworthy services, and devote to the creative reform activities leading in the technical development and career of the industry to create new value through continuous change.

The weldability of EN steel grade S355J2 material is good. It means that under certain process and construction conditions, EN steel grade S355J2 material can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.
