Carbon Steels for Machine Structural use GB GB-45 Steel

JFS Steel has been offering customers special steel materials such as GB-45 Carbon Steels for Machine Structural use and precision steel machining services since 2006. With both highly skilled technology and 47 years of experience, JFS Steel always makes sure to meet each customer's demands. GB 45Mn GB/T 699 - BBN STEEL STORESYield strength is the yield limit of GB 45Mn GB/T 699 when yielding occurs, that is, the stress resisting micro-plastic deformation. The external force greater than the yield strength will make the GB 45Mn GB/T 699 parts permanent failure and unable to recover. Less than this, the GB 45Mn GB/T 699 parts will return to their original shape. GB/T 699 25# Round Bar 25# Round Bar ssroundbarGB/T 699 25# carbon steel is a low carbon steel at chinese standard. Compared with GB/T 699 20# carbon steel, 25# has higher strength. Generally speaking, GB/T 699 25# round bars is used after normalizing treatment, to guarantee the good properties.For GB/T 699 25# carbon steel,we henan bebon can offer forged round bars OD 80 mm 1200 mm.
