Material Cross-Reference Table — AISI / W.Nr / UNS / AMS

MATERIAL CROSS-REFERENCE TABLE — AISI / W.Nr (DIN) / UNS / AMS‌‌

The same material goes by several different names in the industry. Your drawing may say 1.4404, your supplier calls it AISI 316L, and the aerospace specification refers to AMS 5507 — all three are the same material.

The table below brings together the AISI, W.Nr (DIN), UNS and AMS equivalents of the 78 grades we stock, on a single page. Find your code in the matching column, then click the material name for the technical data.‌‌
