Alloy 302HQ is a specialized wire alloy where the addition of 3.00-4.00 copper substantially reduces the cold work hardening rate over 304 stainless. The alloy is non-magnetic in the annealed condition and remains non-magnetic even after substantial cod working. It has excellent toughness even down to cryogenic temperatures.

2001年10月19日 · 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.

uns #s30430 302HQ is a slow work-hardening, austenitic stainless steel used for severe cold-heading applications. Resistant to atmospheric corrosion and a wide variety of inorganic chemicals, it becomes only faintly magnetic after severe cold working.

1.4567 / AISI 304 Cu is an austenitic chromium-nickel stainless steel with copper contents. 1.4567 / AISI 304 Cu is generally the same grade as 1.4301 / AISI 304, except the additional copper content. Good free machining properties.

With the addition of 3.0-4.0 % copper, alloy 302HQ becomes a specialized wire alloy with an extremely low work hardening rate. This makes the alloy ideal for cold heading applications. The alloy is nonmagnetic in the annealed condition and …

Stainless steel 302HQ is a specialize grade for wire with extensive usage for manufacturing stainless steel fasteners. The addition of 3% copper in its composition diminishes the cold work hardening rate considerably compared to stainless steel 304. It has equivalent or exceeding corrosion resistance than stainless steel 304 grade.

The designation 302HQ is not standardised – ASTM specifications list the grade as UNS S30430, and alternative designations for the same grade include "XM-7", "304Cu" and "304HQ". The standard specification for stainless steel fasteners, ISO 3506, includes 302HQ as an acceptable

2021年3月31日 · 302HQ stainless steel is a standard material specifically used in the manufacture of self-tapping screws and light mechanical screws. It is also used in bolts, setting screws, rivets, and special fasteners. The name 302HQ is not standardized. The ASTM lists it as UNS S30430, which also includes “XM-7”, “304CU”, and “304HQ”.

With the addition of 3.0-4.0 % copper, alloy 302HQ becomes a specialized wire alloy with an extremely low work hardening rate. This makes the alloy ideal for cold heading applications. The alloy is non-magnetic in the annealed condition and …
