AISI (SAE) Steels: AISI H13

BACK

AISI H13

Typical analysis

C	Cr	V	Mo
0.40	5.00	1.10	1.30

Designed to resist abrasion and washing action; it has excellent shock resistance. This steel has enough red hardness to retain its properties at high operating temperature.

Typical applications

Dies for hot metalworking ( shearing, forming, punching, extruding and trimming ), dummy blocks and mandrels. Also used for structural applications where high engineering strengths at elevated temperatures are required.
