EN steel grade S420N material MS carbon mild steel sheet and plate

The BBNSTEEL company has the first-class qualification for steel structure professional contracting, integrating production, design and installation, and can undertake various steel structure projects. The product has a wide surface, flat and smooth surface, and neat trimming. It has users in more than 10 provinces and cities in China and is exported to the United States, Canada, Japan, Europe, Southeast Asia and other countries and regions.

Bridge steel plates are steel plates specially used to build railway or highway bridges. It is required to have high strength, toughness and bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The steel EN steel grade S420N material for tie-welding bridges should also have good welding performance and low notch sensitivity。

EN steel grade S420N material, High-strength wear-resistant plates have outstanding performance advantages. First of all, the high-strength wear-resistant plates get their name because their wear resistance is very good, and the degree of wear will not be prominent. Secondly, the corrosion resistance of the high-strength wear-resistant plate is very good. General chemical plants have many corrosive liquids, and the high-strength wear-resistant plates can be used as the floor to reduce risk of accidents.

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized EN steel grade S420N material are higher than that of annealed EN steel grade S420N material, but the elimination of internal stress is not as good as annealing. The normalizing operation of EN steel grade S420N material is simple, the cost is low, the productivity is high, and it is widely used in actual production.

EN steel grade S420N material product plate specification range:Thickness 3-150mmWidth 1500-4020mmLength 4000mm-17000mmHeat treatment: annealing, or normalizing and tempering

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel EN steel grade S420N material plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
