Hot Work

ASSAB boasts a long and wide-ranging experience in the supply of quality hot work tool steel with properties that allow optimum operations at constant elevated temperatures.

Such profile properties include good hot strength as well as excellent ductility and toughness. Other important tool steel properties are a good resistance against thermal cyclic stresses and a good hot wear resistance.

A hot favourite in the ASSAB hot work portfolio is the Dievar with unparalleled ductility, toughness and heat checking resistance together with high hot strength and temper resistance make it the best and natural choice for a wide range of hot work applications but particularly in high pressure die casting.

Coming a close second is speciality grades such as QRO 90 Supreme and Unimax characterising further improved heat resistance and hot wear resistance at elevated temperatures.

Check out other ASSAB tool steel suited for hot work in these common application areas: die casting, hot stamping, extrusion and hot forging.

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.

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.

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 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.

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.

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.

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.
