The diversity of materials we can supply range from ordinary shell-hardenable steel to extremely high-alloy maraging cold-work tool steel. And for every type of application we deliver tailor-made steel grades, which excel themselves through the following properties.
1. very good wear resistance
2. high compression strength
3. excellent toughness
So as to offer tool manufacturers and industrial users optimal conditions, SKI has extended its services
into customer and application-specific consultation, as well as advice on product development.
Deciding on the perfect tool steel with us starts with consulting our cold-work tool steel and high-speed steel specialists. Together with the toolmaker, the demands on the final product and on the required steel grade are defined.
So as to ensure that the client's demands are met, we rely on a highly experienced group of specialists in the cold-work tool steel and high-speed steel area. Together with the tool manufacturers, the specialists constitute a perfectly coordinated team to determine which steel grade and quality is most appropriate to each individual demand profile.

HS6-5-2-5 C 0.92 Cr 4.10 Mo 5.00 V 1.90 W 6.40 Co 4.80
Steel properties
The cobalt content in this high-performance high-speed steel results in high red hardness and tempering resistance. As a consequence, this grade is particularly suitable for conditions involving thermal stresses and discontinuous cutting. Under the name Rapidur 3245, AISI M 35 + S and material number 1.3245, this steel grade is supplied with a higher sulphur content (S = 0.10 %).
Standards
AISI M35 AFNOR Z85WDKCV06-05-05-04-02
Rapidur
3247
HS2-9-1-8 C 1.08 Cr 4.10 Mo 9.50 V 1.20 W 1.50 Co 8.00
Steel properties
High-carbon, high-speed steel based on molybdenum. Characterized by high wear resistance, red hardness and toughness. As a result of its low vanadium content, this grade exhibits good grindability.
