Material cross-reference
Equivalent designations between Japanese JIS and US (AISI/SAE, UNS, AA), European EN and Chinese GB grades for 69 materials, plus the AMS and ASTM specifications commonly used to order them. Most equivalents are close, not identical — chemical ranges and properties differ. Every value on the detail pages (in Japanese) has a cited primary source.

ISO = workpiece material group (ISO 513: P steel, M stainless, K cast iron, N non-ferrous, S heat-resistant/titanium, H hardened). Where tool makers disagree (precipitation-hardening stainless), both groups are shown. Detail pages with composition, mechanical properties and sources are in Japanese.
