These include roughing and finishing stands for hot strip mills, Steckel or heavy plate stands, as well as cold rolling applications or backup rolls.

CROMANIT chrome iron is used for various rolling applications and is known for its very high carbide content. Chromium in particular in higher concentrations but also other alloying elements are added to this material. The alloy therefore offers high wear resistance and hardness, which makes it ideal for demanding and abrasive rolling applications. CROMANIT is versatile and is used in hot and cold rolling processes in various stands, but it is also used in other industries.

ULTRANIT indefinite chill cast iron is an alloyed cast iron with embedded graphite and carbides. This combination provides a characteristic hardness on the one hand and good resistance to fire cracks on the other. Typical areas of application include hot strip mills, Steckel and heavy plate mills as well as cold strip mills and non-ferrous metal production. The material is used for a wide range of roll types.

Micro-alloyed indefinite chill cast iron ULTRANIT S is a further development of the ULTRANIT materials, specially developed for demanding applications in metal processing. This alloy also contains highly wear-resistant special carbides, which are embedded in a fine-grained matrix alongside finely distributed graphite. The micro-alloyed version offers additional properties such as increased wear resistance, increased hardness and improved high temperature strength. Thanks to the special alloying additives, rolls made of ULTRANIT S can achieve a higher rolling performance than normal indefinite chill materials. The areas of application for this material are just as diverse and include various rolling applications in hot and cold rolling processes.

Graphitized HSS TERANIT F is a special variant of the TERANIT materials which was developed for applications where improved heat dissipation is required. This alloy is characterized by the integration of graphite particles that improve the heat dissipation properties and at the same time provides high wear resistance. The use of graphitized HSS TERANIT F is primarily intended for the finishing stands of hot rolling processes and represents a new generation for the replacement of indefinite chill rolls.

Pearlitic spheroidal cast iron, known as SPHÄRONIT, is a special form of cast iron alloy and is characterized by a predominantly pearlitic structure with embedded cementite and spheroidal graphite. This material is characterized by high strength, good thermal conductivity and high toughness and ductility. SPHÄRONIT is used in various rolling applications and for various types of rolls. Among other things, it is chosen for edger rolls or rolls for long products and has been a proven solution for many years.

ASTRANIT materials are characterized by a high alloy content, which ensures excellent wear resistance due to their carbide structure and a bainitic to martensitic structure. This special form of ductile iron offers improved mechanical properties in terms of strength and toughness due to the alloy composition and the specially coordinated heat treatment. It should be noted that intensive cooling is required for optimal performance and durability in use. ASTRANIT is therefore the ideal choice for applications with high wear and friction, especially in the production of long products.

SOLANIT cast steel covers a range of eutectoid to hypereutectoid cast steel qualities. Through specific alloying and complex tempering processes, the hardness and wear resistance are optimized in the various quality levels (SOLANIT A to D). In addition, SOLANIT is also available in graphitized (SOLANIT G) and heavily graphitized (SOLANIT SG) form. These SOLANIT rolls are typically used in edgers for hot strip and heavy plate mills, where they fully exploit their strengths in these demanding applications. In addition, the materials of the SOLANIT Group are also used in a variety of ways in the form of backup rolls or rolls for long products.

DURANIT chilled cast iron is a high-alloy, graphite-free, carbide cast iron known for its hardness and wear resistance. The properties of this alloy are created by pouring liquid cast iron against a mold. DURANIT is often used in applications that are subject to high abrasion stresses, such as wear parts in the ceramics industry. This material is also chosen for hollow cast rolls and calender rolls, where it represents a traditional solution.

Alloyed chilled cast iron DURANIT S is a further development and thus a new variant of chilled cast iron with improved mechanical properties, including higher hardness, wear resistance and toughness. Alloying elements are added in a specific manner to achieve these properties. This alloy is ideal for the demanding applications in rubber, paper and plastics production. This material also offers many advantages for rolls that receive a coating because its excellent mechanical properties contribute to an extended service life of the applied coatings.

CROMANIT K chrome steel is characterized by an impressive carbide structure and hardness of over 80 ShC, which enables improved wear resistance and superior mechanical properties. This alloy is provided with chromium and other alloying elements and subjected to a special heat treatment that is ideally suited to demanding applications that require durability and performance. CROMANIT K rolls are ideal for calendering in the precision range while maintaining extremely tight product tolerances and at the same time offering excellent wear resistance. They can be used both with and without a surface coating and are used in rubber, paper and plastics production.

The CROMANIT S+ material was specially developed for use in the rubber industry and is used in calendering and mixing for rubber mixtures with high silica content. This new material is precisely tailored to the application with special alloying elements and an adapted heat treatment to prevent the rubber mixture from sticking to the rolls. In addition, its properties include excellent wear resistance and high chemical resistance. This results in many advantages for the user because significantly fewer cleaning cycles and less re-grinding are necessary, which in turn reduce cost and increase output. In addition, these rolls have a longer service life, better profile retention and a better release angle, which also have positive effects on overall cost and productivity.

CROMANIT SH chrome steel is a special alloy with very high hardness and outstanding mechanical properties that is used in demanding applications such as the manufacture of battery electrodes. Hardnesses of over 68 HRC can be achieved and the strength is also many times higher compared to forged steel and other materials. CROMANIT SH also has very good wear resistance and can be equipped with various coatings, whereby the durability of the coatings also benefits from the excellent properties of the base material. CROMANIT SH is the only material that has successfully proven its performance in industrial applications and has been able to significantly increase productivity. This material redefines the limits of what is possible.

Forged steel is a special type of steel known for its high strength, toughness and formability. Forged steel is heated to a high temperature and then forged or hammered to achieve the desired shape and strength. This manufacturing method results in a finer microstructure of the steel, making it more resistant to fracture and improving mechanical properties. By inductive hardening the forged steel body, higher hardnesses can be achieved in a thin surface layer. Forged steel is used in a wide range of applications and is used in the form of rolls in cold rolling processes in the steel industry, in the production of plastic film or in the food industry, among other things.

Through the targeted use of special micro-alloying elements in conjunction with intensive heat treatment, all qualities of the individual material groups can be further optimized and individually adapted to customer requirements. This enables customized solutions for different applications and increases the performance of your rolling processes.
