Cold drawn needles are famous for their strength due to the process of cold drawn. Stainless steel cannot be hardened by thermal process such as heat treatment therefore cold drawn process is the solution. They are made from cutting and can be easily integrated with the material. They are widely used in the following sizes: Length- 25-35mm, Diameter- 0.3 to 0.7mm, tensile strength- greater than 650Mpa.
Here are the benefits of reinforcement fibres:
