Hot Forging

In hot forging, a heated billet is pressed between dies in a die set to a close to finished product. This process sees large numbers of solid metal parts produced in aluminium alloys, copper alloys, steel or super-alloys where irregular shapes need to be combined with good mechanical properties.

Choosing the right tool steel

The key to increasing productivity in forging lies in the quality of the tools: excellent hot wear, hot strength, as well as high ductility and toughness.

ASSAB’s steel programme of grades ideal for forging includes QRO 90 Supreme, Unimax, Dievar, Formvar, ASSAB 8407 Supreme, ASSAB 8407 2M and Alvar 14.

Each of them has stood the test of time as a reliable forging tool steel offering different combinations of high thermal conductivity, high resistance to wear at elevated temperature and good hot yield strength.

Formvar is ASSAB’s new addition to its forging tool steel range. It is a significant upgrade from the market’s traditional H13 and H11 forging tools offering good tempering back resistance, hot yield strength and increased tool life. For a forging die, this means better resistance to hot wear and plastic deformation, which also leads to production cost efficiency.

ASSAB 8407 2M

ASSAB 8407 2M is a Cr-Mo-V alloyed tool steel with good ductility, good toughness, good machinability as well as good hot wear resistance. ASSAB 8407 2M is a versatile tool steel which customers find useful in many different applications, primarily hot work applications. ASSAB 8407 2M is DIN standard 1.2344, JIS standard SKD 61 material and is conventionally produced. In markets served by Uddeholm, ASSAB 8407 2M is promoted as Orvar 2M.

FORMVAR

Formvar is a high performance hot work tool steel which offers a very good resistance to hot wear and plastic deformation. It is a solid upgrade choice especially from DIN 1.2344 and 1.2343 forging tools on the market.

DIEVAR

Dievar is ASSAB’s premium steel developed for the demanding application of High pressure die casting. It is the industry benchmark  as the high performance steel for the longest tool life and lowest crack risks due to its superior toughness and ductility. Apart from die casting it has proven itself as a great tool steel for other applications such as forging, extrusion and hot stamping.

ASSAB 8407 SUPREME

ASSAB 8407 Supreme is our trusted premium H13 steel for all kinds of hot work tool applications. Proven over and over again ASSAB 8407 Supreme has stood the test of time and remains well known in the tooling industry for its high and reliable performance and ease of maching. In markets served by Uddeholm, ASSAB 8407 Supreme is promoted as Orvar Supreme.

VIDAR 1 ESR

Vidar 1 ESR is a product suitable for both hot work and plastic mould applications, especially large plastic moulds that require good toughness in combination with high surface finish obtained by polishing or texturing. Vidar 1 ESR is an electroslag remelted (ESR) steel which provides reduction of inclusions in the material.

UNIMAX

Unimax is a high hardness electroslag remelted tool steel which provides great wear resistance even over extended time at elevated temperatures. This product is suitable for coating and nitriding. Unimax performs very well in precision forging, hot stamping and moulding of reinforced plastics.

ALVAR 14

Alvar 14 is a Chromium-Nickel-Molybdenum-Vanadium alloyed tool steel. This product is primarily used in hammer forging applications and as support parts for extrusion tooling, e.g. backers, bolsters. Alvar 14 is DIN standard 1.2714, JIS standard SKT 4 material.

ASSAB 2714

ASSAB 2714 is a Chromium-Nickel-Molybdenum-Vanadium alloyed tool steel. This product is primarily used in hammer forging applications and as support parts for extrusion tooling, e.g. backers, bolsters. ASSAB 2714 is DIN standard 1.2714, JIS standard SKT 4 material.

QRO 90 SUPREME

QRO 90 Supreme is an electro slag remelted steel suitable for applications such as hot stamping, brass forging, die casting core inserts and brass extrusion. With its outstanding thermal fatigue resistance, thermal conductivity and temper back resistance QRO 90 Supreme excels as a tool steels where tools tempers down quickly to lower hardness.
