EN 10025 S550QL1 high strength steel cold bending performance

Carbon steel EN 10025 S550QL1 high strength steel is an iron carbon alloy with carbon content less than 2.11% and a small amount of silicon, manganese, sulfur, phosphorus and other impurities. Carbon steel inevitably contains some impurity elements during smelting, which has a great influence on the performance and quality of steel, so it should be controlled. The quality of carbon steel is mainly measured by the content of sulfur and phosphorus. The lower the EN 10025 S550QL1 high strength steel content of sulfur and phosphorus, the better the quality of carbon steel.

NM400 alloy steel plate is a kind of wear-resistant steel plate. NM—The first letter of the Chinese pinyin 400 of the characters “resistant” and “grind” for wear resistance is the HB value of the Brinell hardness value. NM400 alloy plate is widely used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery and other product parts. Excavator, loader, bulldozer bucket plate, blade, side blade, blade.

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 10025 S550QL1 high strength steel are higher than that of annealed EN 10025 S550QL1 high strength steel, but the elimination of internal stress is not as good as annealing. The normalizing operation of EN 10025 S550QL1 high strength steel is simple, the cost is low, the productivity is high, and it is widely used in actual production.

We have a good inventory system because of which the alloy steel plates and structural steel sheets are supplied and delivered to our customers on time. Our alloy steel plate is significantly affordable than austenitic EN 10025 S550QL1 high strength steel stainless steel which helps to reduce maintenance and full life costs – as well as improved safety over standard boilerplate.
