The manufacturing process of EN steel grade S420N material

We can supply and export EN steel grade S420N material various carbon steel and alloy steel grades. Material: 45 # steel plate, 42CrMo steel plate, Q235B steel, 10# steel plate, 20# steel plate, 45 # steel plate, 16Mn steel plate, 45Mn steel plate, 50Mn steel plate, 65Mn steel plate, 60si2mn steel plate, Q345A steel plate, Q345B steel plate, Q345C steel plate, Q345D steel plate, Q345E steel plate, 20Cr steel plate, 35Cr steel plate. Our steel plates have high demand in several applications thus we are a popular name of the steel product market.

Nowadays, transportation is an important factor in economic development. Our company's rapid development is also inseparable from a good geographical location. The company is located in Zhengzhou, an important EN steel grade S420N material heavy industry area in Central China. Whether you are in Beijing, Shanghai or Guangzhou, you can visit our company very easily. My factory is nearby, convenient transportation and time saving.

At present, the cutting thickness limit of laser cutting is 20 mm. However, it should be noted that oxygen will be added into the laser beam to cut 20 mm thick EN steel grade S420N material steel plate, which will form a thin oxide film on the cutting surface, which may affect the cutting quality, Therefore, attention should be paid to this point to avoid problems.

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of EN steel grade S420N material etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in EN steel grade S420N material etc. steel is strictly controlled.

Our company regularly visits customers, consults and follows up the after-sales service, and directly solves problems for customers. In the use of our steel materials, whether quality problems or not, the after-sales will help solve the problem as soon as possible. We promise free life-long replacement for any product quality problems. The sound after-sales service system make you free from worries.
