BBN supply SA588 Grade K specification cold bending performance

The company adheres to the principle of integrity, standardization and efficiency, wins the market with technology, gains reputation with creative services, and wholeheartedly provides customers with high-quality SA588 Grade K specification, efficient and fast services. Facing the future, adhere to independent innovation.

The metallurgical quality of spring steel should reach the level of high quality steel. Due to the special requirements of production parts, SA588 Grade K specification, spring steel must have some characteristics. First, the fatigue resistance of spring steel is good, and it can be restored to its original state after repeated use without deformation. Second, good flexibility. Third, the tensile strength of spring steel is good, under the limit of being stretched, it can be restored without breaking.

Quenching Improve the hardness of SA588 Grade K specification steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of SA588 Grade K specification steel and comprehensive mechanical properties.

Good news: The largest steel importer in Nigeria ordered 4068 tons API 5L X52Q PSL2 3LPE seamless pipes and also ordered 8 pcs 42699.6 m³big diameter Crude oil storage doom roof tank in A537CL2 steel grade. In Sep 2019, This Nigeria client visited our company and factory, they were very satisfied with our company's quality control,production capacity and service. We also have reached a agreement for Phase II Project, It is also with another 10,000 tons APl 5L X52Q PSL2 3LPE seamless pipes.
