The prehardened steel for extrusion dies and engineering components

Toolox® 44 prehardened steel is suitable for extrusion dies and engineering components that require high strength. It possesses good workshop properties.

Toolox® 44 is a prehardened engineering and tool steel. Despite its high hardness, Toolox® 44 combines very good machinability with dimensional stability during machining.

Its nominal 450 HBW/45 HRC hardness makes Toolox® 44 your ideal choice for demanding mold and die applications. The high steel cleanliness gives Toolox® 44 very good polishing, A2 gloss, and texturing capabilities.

In applications that demand additional surface hardness to counteract wear, you can nitride and PVD coat Toolox® 44 to customize the mold or die properties. Surface engineering can be carried out as long as the deposition temperature does not exceed 590°C (1,094°F).

The challenge

ThyssenKrupp Tallent depends on just-in-time deliveries to keep production up and running. The unavailability of components can bring the entire manufacturing process to a halt, resulting in serious cost consequences. Premature cracking of the company’s blanking die threatened to jeopardize its ability to consistently produce quality components and secure future orders — and lose business altogether.

The solution

The company turned to Toolox® 44, deciding to produce and nitride a new die to protect the edges during blanking.

Soon after the Toolox® die was put into production, it became obvious that it was far superior to dies that use conventional tool steels. Toolox® 44 remained intact and the die became a major success, receiving more than 255,000 blows without any negative effects.

Customer benefits

Using Toolox® 44 has significantly improved the die life, bringing greater productivity, improved profitability and more on-time deliveries. The company has also seen a reduction in die manufacturing time, resulting in lower production costs.

And because the heat treatment is carried out by SSAB, high quality and consistency are guaranteed in every piece of steel. In fact, when a customer buys Toolox®, SSAB guarantees that all of the properties in every piece of steel meet stringent quality standards — a unique offering in the market today.
