Stainless Steel 1.4567 | AISI 302 HQ | AISI 304 CU

1.4567 AISI 302HQ AISI 304Cu data sheet

Data sheet
DIN EN 10088-3
Grade AISI 302 HQ / AISI 304 Cu


The austenitic material 1.4567, which is comparable to both AISI 302 HQ and AISI 304 Cu, is a chromium-nickel stainless steel. It differs from the otherwise similar material 1.4301 / AISI 304 in its copper content of 3-4 %, which contributes to the fact that stainless steel 1.4567 is ideally suited for cold forming. It can also be used at low temperatures.

The material 1.4567 has good forging properties and good corrosion resistance (but not to salt water). It is used, among other things, in the automotive industry and for the production of screws.
