Tool Steel

A series, D Series, S Series
We sell a wide variety of tool steels in sheet, plate and cut to size pieces. Below is a list of what we carry, a summary of their key characteristics and typical alloy content.

The A series tool steels are characterized by their high hardenability and dimensional stability in heat treatment. They can all be hardened by air cooling and are suited for cold work applications.

Chemical requirements, Percent (Maximum unless otherwise noted)

Grade C Mn P S Si Cr V W Mo
A-2 .95/1.05 1.00 .03 .03 .15/.50 4.75/5.50 .15/.50 - .90/1.40
A-6 .65/.75 1.80/2.50 .03 .03 .15/.50 .90/1.20 - - .90/1.40

All D series steels are resistant to softening at elevated temperatures. These steels also exhibit excellent wear resistance, especially D7, due to its high carbon and vanadium content. D series tool steels all contain 1.5 to 2.35 percent carbon and about 12 percent chromium which contributes to the hardenability of these alloys. Typical applications for this class of steel are shear blades, brick molds, and slitter knives.

All S series steels are characterized by their toughness and resistance to shock. The principle alloying elements in S series steels are manganese, silicon, chromium, tungsten and molybdenum. We carry S-1 ESR which is a premium melted S-1. Common applications for this group of steels include chisels, punches and blades for fin tubing.
