10B21 10B21M 10B33 10B35 Cold heading wire rod
10B21 10B21M 10B33 10B35 Cold heading wire rod
10B21、10B21M、10B33和10B35 are mainly used for the production of 8.8 ~ 12.9 grade standard parts. The products have the advantages of stable composition, low harmful elements, high purity of steel, small decarburization layer, less surface defects, low cold header cracking rate, low original hardness of wire rod, high strength after heat treatment, good hardenability and so on.
Size:φ5.5~42mm
Application:be used for grade 8.8-12.9 fastener production
