HSLA structural BP300 steel thickness range yield strength

S50C steel plate is a high-quality high-quality medium carbon steel. S stands for steel, which means iron, and 50 stands for carbon content of 0.50%. C represents carbon steel, which means that S50C is a carbon steel with a carbon content of 0.50%.Mechanical properties of S50C steel plate:Tensile strength σb (MPa): ≥630 (64); Yield strength σs (MPa): ≥375 (38); Elongation δ5 (%): ≥14; Reduction of area ψ (%): ≥40; Impact Work Akv (J): ≥31(4); Impact toughness value αkv (J/cm2): ≥39(4)Hardness: unheated, ≤241HB; annealed steel, ≤207HB

Our company was founded in 2000, which initially committed to providing high-quality steel BP300 steel thickness range products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export BP300 steel thickness range steel to the international market, opening up the international steel market.

How to distinguish between hot rolled and cold rolled process?The hot-rolled steel sheet has low strength, easy production and processing, and good plasticity. The process performance of the hot-rolled steel plate is poor (air oxidation and low smoothness), but the plastic deformation is good. Generally, it is medium and thick plate, BP300 steel thickness range, high compressive strength, high strength, and high surface smoothness. Cold-rolled steel sheets have high strength and relatively difficult production and processing, but they are not easy to deform and have high compressive strength.

The purpose of alloying Q345B steel is to use the interaction of alloy elements with iron and carbon and the effect on iron-carbon phase diagram and the heat treatment of steel to improve the structure and properties of steel. Interaction of alloying elements with iron and carbon: After alloying elements are added to steel, they mainly exist in steel in three forms. That is: forming a solid solution with iron; forming carbides with carbon; and possibly forming intermetallic compounds in high alloy steels, BP300 steel thickness range.

Customer first, reputation first, high-quality and perfect after-sales service is the extension of our product value and an important guarantee for the interests of customers. The purpose of our BP300 steel thickness range service quality management system is to establish and constantly improve a scientific, reasonable and efficient service quality management system, and complete the after-sales service quality guarantee work of customers fairly, accurately and timely, For our company's BP300 steel thickness range customer service to establish a good, comprehensive, full service system.
