302HQ XM-7 304CU Stainless Steel Coil Rolls UNS S30430 2B Annealed Tempered For Fasteners

XM-7, 304CU, 304HQ Coil, Wire, ASTM A493, 302HQ overview

302HQ is a specialised wire grade finding very wide usage for manufacture of stainless steel fasteners. The inclusion of 3% copper in the composition reduces the cold work hardening rate substantially compared to Grade 304. This grade is the standard material for manufacture of self-tapping screws and light machine screws and is also used for some bolts, set screws, rivets and specialised fasteners. 302HQ has now totally replaced Grades 384 and 305. Alternative designations for Grade 302HQ include "XM-7", "304Cu" and "304HQ". The stable austenitic structure makes 302HQ non-magnetic, even after substantial cold work, and also results in excellent toughness, even down to cryogenic temperatures.

Coil Slitting Mill Capability :

Striping processing, commonly known as “slitting “, refers to the winding of a metal coil by unwinding, slitting, leveling, winding, and processing into a desired width. Slitting processing is a basic metal processing technology that combines high-quality equipment with skilled craftsmanship. it can be obtained with strict tolerance, perfect surface control , safe packaging as well as fine transportation.
