Tool steel grades are machined to various finishes to be used for a lot of applications like open die forgings.

Copper Round Bar Tool steel is machined out of various tool steel grades that are critically picked for their suites applications. Each grade differs regarding with their featured properties and strengths as well as for their combined element contents.

They are most suited for die forging applications with the great toughness and hardness they have which allow them to be used mostly in machining and cutting other metals.

Please see our table of tool steel grades below:

A2 medium air hardening tool steel; capable of deep hardening slitters, die shapes, and similar applications
A10 keeps distortion at minimum level upon hardening thread rolling dies and intricate die shapes
D2 high chromium, high carbon type tool steels; highly wear resistant; deep hardening alloy thread rolling dies and blanking and forming dies
D3 has high wear resistant; deep hardening alloy; has high comprehensive strength forming rolls, draw dies, blanking and forming dies, powder metal tooling
D5 capable of deep hardening; has low resistance to heat softening blanking and forming dies, thread rolling
H11 chromium, hot work type tool steels; has good toughness; low in carbon content aircraft landing gear
H13 contains strengthening agents; softening resistant at high temperatures die casting, die work, extrusion dies
H21 has tungsten content; toughness reduced used for tolling and hot working dies
H26 softening resistant; has higher tungsten content forming dies and hot extrusion
M2 higher version of M1 tool steel; has better wear resistance cutting tools
P20 mold steel; has high hardness and toughness injection molds and die casting dies
W1 simple high carbon steel; easily hardened by quenching and heating cold heading, metal cutting tools, embossing taps and reamers, cutlery
