CHQ wire

*Scroll to right

CHQ Wire is a wire for Cold Heading or Cold Forging( a process method in a room temperature), one method of metal forming, A stric quality level is required for the internal (structure, internal defects) and external (dimensions and surface conditions) properties.
We have been supplying excellent quality of CHQ Wire domestic & oversea industries with the state-of-the-art facilities such as Hydrogen Bell Type furnace and automatic pickling & coating lines, etc.
