  • Grade 9.8 Bolt

Class 9.8 Hex Bolt, Threaded Rod and High Tensile Grade 9.8 Stud Bolt manufacturer in India

The ISO 898 or the Sae Class 9.8 is an international standard which defines both the mechanical as well as the physical properties for metric fasteners. The Iso 898 Class 9.8 standard is the origin for other standards such as the Sae J1199 Class 9.8  and the ASTM F568 Class 9.8 which are known to define properties for similar metric fasteners. The specification Fastener Grade 9.8 standard covers those fasteners  that have been manufactured from Medium carbon steel between the size range of  M1.6 - M16. These  Metric Class 9.8 standard fasteners are processed by Quenching and tempering.

There are two methods used to form the alloy of Class 9.8 Material

  • Chip removal
  • Cold deformation

During chip removal process, the layers of metal from the parent metal or workpiece separated. The excess layer is separated in the form of chips, thereby shaping the work piece into the required shape and dimension. Besides determining the shape characteristics of the Class 9.8 Bolt, this process achieves a finished surface in the 9.8 Metric Bolt. Cold deformation also known as cold working is when the alloy of M 9.8 Bolt has been induced to plastic deformation for the purpose of  exacting a change in the shape of the alloy. Cold deforming the Class 9.8 Screw alloy offers several benefits to the end product. For e.g. – Cold working enhances the Grade 9.8 Bolt Properties by increasing the hardness, yield strength and tensile strength. The tensile strength of the 9.8 Bolt Socket is as high as 900 Mpa.
