302HQ strip is an austenitic alloy optimized for cold heading. Modified from 302/304 grades, it features a low work-hardening rate, allowing severe deformation without cracking.
Key Properties
Cold Heading: "HQ" means High Quality for heading. Excellent ductility allows significant deformation without fracturing, superior to standard 304 for fasteners.
Strength: Soft enough for forming but achieves high tensile strength after cold working.
Corrosion: Similar to AISI 304; resists oxidation and rust in mild environments.
Magnetism: Non-magnetic when annealed; slightly magnetic after cold work.
Common Applications
Widely used for room-temperature shaping:
Fasteners: Screws, bolts, nuts, rivets.
Electronics: Pins, connectors, lead frames.
Auto Parts: High-strength precision components.
Household: Zippers, hooks, formed accessories.
