What Are The Mild Steel Plate EN steel grade S460QL material Properties

The ASTM A572 EN steel grade S460QL material specification refers to high-strength low-alloy steel plates used in structural buildings. Among the five steel grades 42, 50, 55, 60 and 65, grade 50 is the most common in applications requiring higher strength and lighter weight. One of the EN steel grade S460QL material steels, the steel plate of this brand other than ordinary carbon steel is used, so that the steel structure has the same steel strength, but the weight is lighter.

Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, EN steel grade S460QL material based on a high starting point and high technology, the company has vigorously developed various steel products EN steel grade S460QL material and deep-processed parts, steel structures, precision castings, seamless pipes.

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 S460QL material are higher than that of annealed EN steel grade S460QL material, but the elimination of internal stress is not as good as annealing. The normalizing operation of EN steel grade S460QL material is simple, the cost is low, the productivity is high, and it is widely used in actual production.

Rolled sheet is a very common material in industrial construction. Rolled sheet at room temperature is cold-rolled sheet, and cold-rolled sheet is the rolling of hot-rolled coils below the recrystallization temperature. The hot-rolled sheet is rolled above the recrystallization temperature. So what is the difference between EN steel grade S460QL material, hot rolled sheet and cold rolled sheet?

The company's after-sales service tenet is "customer first, timely guarantee, enthusiastic service and effective work". In order to establish a set of perfect after-sales service system and strict management system, so that the after-sales service can be effectively guaranteed. The company has set up after-sales service department to ensure timely, unique and effective response to every user's request, coordinate internal resources internally, and put an end to all evasion and delay.
