Fabrication and Heat treatment
D7 tool steel is slowly heated at 1093 - 1149C (2050 - 2100F). The forgings are then cooled slowly in dry sand or in other insulating media.

D7 tool steel is heated at 871 - 899C (1600 -1650F) for 2 hours and cooled to 538C (1000F).

Stress Relieving
To relieve machining stresses, A11 tool steels are heated to a temperature of 621 - 677C (1150 - 1300F) and then slowly cooled in still air.

D7 tool steel is hardened at (1900-2000F) and slowly cooled in air.

Tempering of D7 tool steel is carried out at (400-1000F) for 1 h.

The following are the list of applications of D7 tool steels:
· Brick mold liners
· Powder compaction tooling
· Shot blasting equipment liners
· Flattening rolls
· Powder compaction tooling
· Tools for ceramic extrusion and molding.

The AISI grades of tool steels are the most common scale used to identify various grades of tool steel. The higher carbon grade tool steels are typically used for applications such as stamping dies, metal cutting tools, etc.
AISI D7 tool steel is a high-carbon, high-chromium air-hardening tool steel that exhibits exceptional wear resistance, with added carbon and vanadium.
The data below will provide an overview of grade D7 tool steels.
