Edition 8 09.20162 Uddeholm Vanadis 30 SuperClean Uddeholm Vanadis® 30 SuperClean Uddeholm Vanadis 30 SuperClean is a Co high alloyed powder metallurgy high speed steel corresponding to AISI M3:2 + Co. The high compressive strength, 67 HRC, and good abrasive wear resistance makes Uddeholm Vanadis 30 SuperClean suitable for demanding cold work applications and for cutting tools as an alternative to AISI M42 or other Co-alloyed HSS. The P/M process gives a good machinability and grindability as well as a good dimension stability during heat treatment. 3 Uddeholm Vanadis 30 SuperClean APPLICATIONS PROPERTIES Uddeholm Vanadis 30 SuperClean is a cobalt PHYSICAL DATA alloyed high performance PM high speed steel.

  • Press Release As PDF: Voestalpine Company Uddeholms AB Is
    voestalpine AG PRESS RELEASE June 28, 2018 voestalpine company Uddeholms AB is celebrating 350 years of innovation at the site in Hagfors, Sweden Founded in 1668 as a family-run iron mill in Värmland, southern Sweden, today Uddeholms AB is a global market leader in the production of special steels for toolmaking. With sales sites and partners in over 90 countries, the company supplies the global automotive, mechanical engineering, and consumer goods industries with sophisticated steel grades from Hagfors. Uddeholms AB has a workforce of 900 employees at its headquarters and generated revenue of EUR 305 million in the past business year. Over the past ten years more than EUR 130 million has been invested at the site—intensive development of digitalization technologies and the production of metal powder for 3D printing will secure the future of this site with its long history. Over a period of three and a half centuries, the former family-run company in Hagfors has advanced to become a global player in tool steel. In 1991 Uddeholms AB and Austrian-based special steel manufacturer Böhler combined to form Böhler-Uddeholm AG which was subsequently listed on the Vienna Stock Exchange. The group was taken over by voestalpine in 2007 and is now part of the Group’s High Performance Metals Division. “With its know-how in developing and manufacturing high-tech steels, and its global customer network, Uddeholms AB has played a significant role in making our Group more specialized and international over the past decade. To mark the occasion of today’s anniversary, my particular thanks go to the employees in Hagfors.

  • Testing New Tribo-Systems for Sheet Metal Forming of Advanced High Strength Steels and Stainless Steels
    E. Ceron et al.: Testing new tribo-systems for sheet metal forming of advanced high strength steels and stainless steels TESTING NEW TRIBO-SYSTEMS FOR SHEET METAL FORMING OF ADVANCED HIGH STRENGTH STEELS AND STAINLESS STEELSI E. CERON1, N. BAY2*, 1Grundfos A/S, Poul Due Jensens Vej 7, 8850 Bjerringbro, Denmark. 2Dep. of Mech. Eng., Technical University of Denmark, Produktionstorvet 425, 2800 Kgs. Lyngby, Denmark. ABSTRACT Testing of new tribo-systems in sheet metal forming has become an important issue due to new legislation, which forces industry to replace current, hazardous lubricants. The present paper summarizes the work done in a recent PhD project at the Technical University of Denmark on the development of a methodology for off-line testing of new tribo-systems for advanced high strength steels and stainless steels. The methodology is presented and applied to an industrial case, where different tribo-systems are tested. A universal sheet tribotester has been developed, which can run automatically repetitive Bending Under Tension tests. The overall results show that the methodology ensures satisfactory agreement between laboratory tests and production tests, although disagreement can occur, if tribological conditions are not the same in the two cases. Keywords: Sheet metal forming, off-line testing of tribo-systems, galling. *Corresponding author: Niels Bay ([email protected]). INTRODUCTION achieve, and custom built laboratory tests have been developed for the simulation of New, stricter regulations on handling of deep drawing and ironing operations [4]. If chemical products, such as REACH [1], and they show satisfactory results, the new tribo- the new “green” trend in some companies system is tested in production.

Ledeburitic 12 % Cr-steel are still the most commonly used tool steel for cold work tooling all over the world. PROPERTIES PROFILE Uddeholm Sverker 21 is a tool steel with very good abrasive wear resistance but with rather limited cracking resistance. Being the bulk grade for cold work applications there are many advantages such as well established know-how concerning all types of treatments and tool processing. The risk with the popularity is, however, that the grade by routine is used in applications where the properties profile not is entirely appropriate. In such cases normally there are better alternatives like Uddeholm Sleipner, Uddeholm Caldie or Uddeholm Vanadis 4 Extra. APPLICATIONS The properties profile of Uddeholm Sverker 21 combine to give a steel suitable for the manufacture of medium run tooling for applications where abrasive wear is dominant and the risk of chipping or cracking is not so high, e.g.

Edition 15, 10.2017 2 Uddeholm Cladie Uddeholm Caldie® CHANGING TOOLING ENVIRONMENT New and more demanding work materials are continuously imple- mented in the industry. As a consequence of the introduction of AHSS, Advanced High Strength Steel, the forming tools have to resist higher stress levels and withstand more adhesive and abrasive wear. Many times the tool has to be coated in order to fulfil production require- ments, i.e. the tool material also has to be a good substrate material for different type of surface coatings. THE PROBLEM SOLVER Uddeholm Caldie is the first ESR-grade and developed with main focus on severe cold work applications. The excellent combination of compressive strength, wear resistance and chipping/cracking resistance has been achieved by a well balanced chemis- try of matrix type and a clean and homogeneous microstructure. Appropri- ate heat treatment properties and high fatigue strength make Uddeholm Caldie also to a perfect substrate material for surface coatings A VERSATILE TOOL STEEL The unique properties profile of Uddeholm Caldie include very good weldability, castability, through hardening properties, machinability and grindability.
