1inch structural steel EN steel grade S460QL1 material for sale

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 S460QL1 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 S460QL1 material etc. steel is strictly controlled.

Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the EN steel grade S460QL1 material steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its EN steel grade S460QL1 material steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.

High-strength steel plates have the following characteristics. First, the strength is high, the bearing capacity is very good, and it is not easy to break. Second, compared with other steel plates under the same strength requirements, high-strength steel plates are lighter and thinner, which can effectively reduce the weight of structures. Third, the EN steel grade S460QL1 material, high-strength steel plates are required to be safe and reliable, able to withstand complete disasters such as water, fire, earthquake, storm, etc., to protect people's safety.

Q215 steel has good plasticity and weldability. Q235 steel has certain strength, plasticity, toughness and weldability. Q235 steel is easy to punch and can meet the use of steel structure. Q255 steel has high strength, good plasticity and weldability, and its application is not as extensive as Q235 steel. Q275 steel has high strength, poor plasticity and weldability. Q275 steel is used for shafts, connecting rods, gears, keys and metal components with high strength requirements.
