BBN steel make efforts to reduce cost of EN steel grade S460N material

Q370R steel and 15CrMoR plates have low sulfur and phosphorus content, and have good comprehensive mechanical properties, welding performance and low temperature impact toughness. Q370R low alloy steel is suitable for manufacturing medium temperature and low pressure pressure vessels and their accessories. EN steel grade S460N material, 15CrMoR material has low sulfur and phosphorus content, and has good welding performance and impact toughness.

Since it was established in 2000. Based on the domestic rich EN steel grade S460N material product resources and the great steel demand of the international market, our EN steel grade S460N material service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products

Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium EN steel grade S460N material carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some EN steel grade S460N material alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.

With the increase of temperature, the yield limit of EN steel grade S460N material will decrease monotonically, but the tensile strength of EN steel grade S460N material will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of EN steel grade S460N material. Near the blue brittleness temperature, the EN steel grade S460N material strength increases and the plasticity decreases. The elongation and section shrinkage of EN steel grade S460N material increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.

The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible. At the same time, a traceable product traceability system has been established. It has always been placed at an important core position to resolve customer worries. Our steel EN steel grade S460N material products are always committed to “quality issues, life-long replacement”, which is the embodiment of our comprehensive service.
