Do you know the thickness range of BBN Steel's hydrogen sulfide resistant steel plate? The A588 grade A structural steel plate product thickness is between 8-180mm. Q345RHIC steel and Q345RR-HIC test environment: A solution HIC steel (HIC-A) and B solution HIC steel (HIC-B) Q345RHIC and Q345RR-HIC test items: tensile, bending, thickness direction properties, grain size, Brinell Hardness, ultrasonic flaw detection, HIC test, impact test, high temperature tensile test, SSCC test, melting analysis, finished product analysis.
Based on the advantages of A588 grade A structural steel plate steel resources in domestic market and good reputation, combining with the huge international market demand for steel products, our company started the international business in 2010 and successfully being approved and certified by ISO9001:2008, the Registration number is 626014Q11531R0S. With the quality steel A588 grade A structural steel plate products and professional service, our company was award the international acclaim from infrastructure, shipbuilding, petroleum industry etc., and gradually grow into a bright star in the steel export industry .
The main applications of normalizing are as follows:① For low carbon steel, A588 grade A structural steel plate. The hardness of low carbon steel after normalizing is slightly higher than that after annealing, and the toughness is also better, so normalizing can be used as the pretreatment of cutting.② For medium carbon steel, normalizing can be used as the final heat treatment instead of quenching and tempering treatment, or as the preparation treatment before surface quenching by induction heating.③ Normalizing can be used in tool steel, bearing steel, carburizing steel and so on, which can eliminate or inhibit the formation of network carbide, thus obtaining the good microstructure needed for spheroidizing annealing.④ Normalizing can refine the cast structure and improve the machinability of steel castings.
Oxygen (O) is a harmful element in steel such as A588 grade A structural steel plate. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.
As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality A588 grade A structural steel plate products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
