Product description

Specifications spring steel wire-flat bar 5.5mm SUP9,SUP9A

spring steel wire-flat bar GB/T4354-1994 and enterprise standard is executed for this product. The main grades are 45~80, SWRH42A~82A and SWRH42B~82B. With higher comprehensive mechanical performance after quenching and tempering treatment for this grade, it could be used to manufacture steel nails and mechanical components. With higher strength, hardness, elasticity and wearability, the high carbon steel wire rod could be used to make steel wire rope and spring, but it is not suggested to be used in the production of tire bead steel wire, flose wire or steel cord. In 2002, the hot rolled high quality carbon steel wire rod produced by our company won the Golden Cup Prize of metallurgical product quality and title of Famous Brand of China in 2007. Specifications: 5.5mm-13mm
