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.
