| A-2 is an air-hardening die steel, intermediate in abrasion resistance between D-2 and O-1. A-2 is one of Latrobe's most popular die steels. It possesses excellent non-deforming properties, is deep hardening, and has good toughness properties. | x | x | x | x | |
| D-2 is an air hardening high carbon-high chromium die steel well suited for long run tool and die applications. An abundance of extremely hard, wear resisting alloy carbide particles imparts excellent abrasion resistance qualities to D-2. | x | x | x | x | |
| S-7 is an air or oil hardening die steel with a unique combination of toughness and wear resistance properties making it an ideal choice for many tooling applications. It is suitable for dies used in plastic molding and other applications where operating temperatures are below 1000 degrees. | x | x | x | x | |
| O-1 is an oil hardening, non shrinking die steel which can be hardened at relatively low temperatures. Tools and dies made from o-1 have good wearing qualities since the tungsten and higher chromium content gives improved wear resistance over the straight manganese types | x | x | x | x | |
| 4140 is excellent for tooling and maintenance applications and numerous machine component parts. The countless applications include backup and support tooling, die details, short run dies, spindles, brake dies, axles, bolts, forming rolls and other machine tool components. | x | x | x | x | |
| A-6 is a medium alloy, air hardening die steel with non-deforming properties making the grade an ideal choice for many die and mold applications. | x | x | n/a | x | |
| H-13 is a chromium die steel which is an excellent choice for a wide range of hot work and cold work applications. It is widely used for aluminum, zinc, and magnesium die castings where resistance to thermal fatigue die to alternated heating and cooling cycles is of primary importance. | x | x | n/a | n/a | |
| Viscount 44 is a fully heat treated H-13 hot work steel with carefully controlled and evenly dispersed sulphide additives. Viscount 44 has a tremendous advantage when used for hot work dies because of the constant danger of size change or distortion during heat treatment. It is an excellent choice for die casting dies. | x | x | x | n/a | |
| Vertex is a chromium-molybendium, general purpose cold work steel. Vertex is the newest cold work tool steel that offers wear resistance of D-2 and toughness similar to S-7. This material is easily heat treated in a conventional heat treat furnace. Hardness ranges from 62 rc to 59 rc when heat treated correctly. | x | x | n/a | n/a |
