Heat TreatmentHints on heat treatment:

• Specify heat treatment, in writing, for each project.

• Stress relieve after rough machining and prior to semi-fi nish machining.

• Semi-fi nish machine parts to allow proper heat treatment.

• Load furnaces to minimize distortion and maximize the rate and uniformity of cooling.

• Heat tools to hardening temperature without degrading properties.

• Quench quickly, minimize distortion.

• Temper tool to obtain desired working hardness and optimum tool properties.

• Perform stress tempers on hardened tools after EDM, welding, or during preventative maintenance.

• Request documentation of all heat treatment processes.

• Use a quality heat treater who has the equipment and expertise to do the job right the fi rst time.

• Allow suffi cient time for the heat treatment processes to be performed correctly.

For more detailed information, consult our heat treatment guidelines, or contact our own heat treatment experts at BOHLER-UDDEHOLM Thermo-Tech.

Die material propertiesThe properties profi le required for tool steels in forging dies depends to some extent on the type of forging operation, on the work material and on factors such as the size of the part and the depth of impression. However, a number of gen-eral characteristics will always be required in all forging operations. The particular failure mechanisms and the means for resisting their onset are listed below

• Suffi cient hardness and ability to retain this at elevated temperature – temper resistance (wear, plastic deformation, thermal fatigue cracking).

• Enhanced level of hot tensile strength and hot hardness (wear, plastic deformation, thermal fatigue cracking).• Good toughness and ductility at low and elevated temperatures (gross cracking, thermal shock cracking, and ther-

mal fatigue cracking). It is important that the die steel exhibits adequate toughness/ductility in all directions.• Adequate level of fatigue resistance (gross cracking and heat checking).• Suffi cient hardenability (retention of wear resistance, etc., if the die is resunk).

Hot ForgingDuring the hot forging process, a heated billet or blank is pressed between a die set to form a nearly fi nished product. Large numbers of solid metal parts are pro-duced from aluminum, copper, steel or super alloys. The hot forging process is particularly suitable for producing components with irregular geometries that are exposed to demanding service environments. The primary meth-ods of impression die forging are drop/hammer forging and press forging.

Hot forging dies are exposed to severe mechanical and thermal cyclical loading. Their operating environment promotes the onset of hot wear, cracking and plastic de-formation of the die. To delay or prevent the occurrence of such phenomenon, the use of tool steels with superior hot strength and ductility are essential.

Böhler-Uddeholm off ers a comprehensive group of forg-ing die steels designed to optimize tool life for every type of service environment. For example, BOHLER-UDDE-HOLM H13 and BOHLER W303 ISODISC are the bench-marks for standard hot forging applications. However, if better resistance to breakage is required, Uddeholm Formvar should be considered. When H13 dies are ni-trided and need better erosive wear resistance, consider VILLARES VEX. For overall hot hardness, use BOHLER W360 ISOBLOC. When forging brass and other copper alloys, BOHLER W403 VMR shows excellent die life and the BOHLER-UDDEHOLM L718 is designed for the most extreme forging temperatures.

Semi hot / warm forgingWarm forging is a precision forging operation carried out at a temperature range of 1020-1740°F (550-950°C). It is useful for forging components with intricate shapes, to create a desired grain fl ow pattern, produce a good surface fi nish and generate tighter dimensional tolerances. The weight of the forged piece is typically between 0.2-110 lbs. and the production rate is approximately 10-40 pieces per minute. The typical contact time between workpiece and die is 200 ms. As an example, the mechanical loads, at 1110°F (600°C), may be 3-5 time higher than those used when hot forging. Automatic multi-station presses with integrated cooling/lubricating systems are often used.

In semi-hot or warm forging, the tool parts are subjected to very high mechanical loads and intensive cooling. This leads to excessive die wear and eventually thermal fatigue. To extend tooling life under such conditions, the use of tool steel with a high-level of hot strength such as BOHLER W360 ISOBLOC is recommended. When extremely good ductility is required, use Uddeholm Dievar or BOHLER W403 VMR.

Progressive forgingIn progressive forging, a large number of symmetrical precision-forged parts with forged weights of up to about 11 lbs. are produced. The fully automated process involves supplying hot-rolled bars at one end of the line, heating them inductively, cutting them to the required size, shaping them in 3-4 stages and discharging fi nished forgings at the other end of the line. Depending on the weight of the forgings, production capacity is between 50-180 per minute.

Very high stresses and thermal shock in production lead to wear and thermal fatigue. For best results, use materials with very good hot strength such as BOHLER W403 VMR or BOHLER W360 ISOBLOC. Where thermal shock resistance is needed, use Uddeholm Dievar. When moderately priced improvements over H13 are required, consider Uddeholm Formvar, VILLARES VEX, and BOHLER W303 ISODISC.

Benefi ts are: high hardness and wear resistance, superior abrasion and erosion resistance, corrosion resistance from alloying attack, high oxidation temperature and thermal stability and improved coeffi cient of friction.When an increase in production, extended tool life, less down time, and higher tool performance are requirements, then eifeler Coatings Technology is your solution provider.

CROSAL - The newest generation of AlCrN coatingThis innovative AlCrN-based high-performance coating was specially developed for use at high temperatures, up to 2012°F (1100°C).

Locally high to very high temperatures occur in many forging processes. Our innovative CROSAL® coating meets all the necessary demands to the highest degree: high hot hardness, high resistance to oxidation and high adhesive strength.

Heat TreatmentHints on heat treatment:

• Specify heat treatment, in writing, for each project.

• Stress relieve after rough machining and prior to semi-fi nish machining.

• Semi-fi nish machine parts to allow proper heat treatment.

• Load furnaces to minimize distortion and maximize the rate and uniformity of cooling.

• Heat tools to hardening temperature without degrading properties.

• Quench quickly, minimize distortion.

• Temper tool to obtain desired working hardness and optimum tool properties.

• Perform stress tempers on hardened tools after EDM, welding, or during preventative maintenance.

• Request documentation of all heat treatment processes.

• Use a quality heat treater who has the equipment and expertise to do the job right the fi rst time.

• Allow suffi cient time for the heat treatment processes to be performed correctly.
