Cold drawing wire for drawing No. 10 steel wire rod standard parts

Grade: No. 10 steel

Implementation standard: GB/T699-1999

Manufacturing parts that require low stress and high toughness, such as automobile bodies, containers, deep-drawn vessels, pipes, gaskets, etc., can be used for cold rolling, cold stamping, cold heading, cold bending, hot rolling and other forming processes. It can also be used as carburized parts and carbonitrided parts with low core strength.
