Heat treatment Related

Forged of D3 Tool steels

Slowly heated the D3 steel material to 650-680°C (1202-1256°F) before raising the temperature to 1050-1100°C (1922-2120°F) and soak D3 tool steel material until uniformly heated. Initial hammer blows should be light due to the comparatively high hot strength of this steel.

The D3 steel forged temperature should be maintained above 1000°C(1832℉) until the D3 steel metal begins to yield. Final forged should not be done below 900°C(1652℉). Slowly cool after forged is essential to avoid the possibility of cracking.

Annealing of tool steel D3

Slowly heated D3 steel to 850-870 ℃(1562-1598°F) and allow enough times, let the steel to be thoroughly heated, Then cool slowly in the furnace at a rate of 4°C (40°F) per hour or less.. The D3 tool  steel will get MAX 250 HB (Brinell hardness).

Hardening of D3 tool steel

D3 steels should be heated uniformly to 790-820°C (1436-1508°F) until completely heated through. Then heated to the hardening temperature of 950-980°C(1742-1796℉), soak at the temperature enough time, let D3  steel to be thoroughly heated .

Then withdraw D3 steel tools from the furnace ;either air cool or oil quench.

Tempering of D3 steel tool

Tempering of D3 steels is performed at 150-400°C (302-752°F), Soak well at the selected temperature and soak for at least one hour per 25mm of total thickness. Get Rockwell C hardness of 57 to 62. Others different Heat treatment temperature will get different hardness. Below only for reference.

Other types of Tool Steel Grades :-

A2 Tool Steel

A2 tool steel is an air hardening, cold work, chromium alloy die steel that is preferable to O1 tool steel in applications requiring greater size stability, machinability and safer hardening. The wear resistance properties and cost place A2 between that of O1 and D2 tool steel making it a good all purpose grade for many applications. The increased wear resistance and lower distortion make A2 tool steel particularly useful in longer production runs on either light or heavy gauge stock. Applications include: blanking dies, forming dies, trimming dies, stamping dies, coining dies, drawing dies, extrusion dies, punches, shear and slitter blades, gauges, knurling tools, rolls, mandrels and machine parts. Common trade names include Air-True, Windsor, Airkool, AL4, Select B, Thyrodur 2363, Airque, Sagamore, Cromo-Loy, EZ-DIE, A-H5.

D2 Tool Steel

 

D2 tool steel is an air-hardening, cold work, high carbon, high chrome tool steel with exceptionally high wear resistance properties. D2 tool steel properties combine minimal distortion in heat treatment, high toughness and wear resistance at the expense of grindability and machinability compared to other grades. Its deep hardening ability helps it to resist chipping and cracking. These characteristics along with price make D2 tool steel a high performance choice for applications requiring maximum dimensional stability in heat treatment, toughess, and wear resistance for longer life in long run, high production die applications. These applications include knife blades, thread rolling dies, lamination dies, blanking dies, forming dies, trimming dies, stamping dies, coining dies, drawing dies, extrusion dies, punches, punch plates, shear and slitter blades, gauges, knurling tools, rolls, mandrels and machine parts.

H13 Tool Steel

 

H13 tool steel is air-hardening, hot work 5% chrome tool steel. It combines excellent shock and abrasion resistance with good red hardness making it ideal for use in die casting. Most commonly used in plastic molds and die casting, its ability to withstand rapid cooling from high working temperatures also make it a prime choice for use in extrusion dies. While designed to be a versatile hot work grade, H13 tool steel has been useful in cold work applications as well, particularly when extra toughness is desired but wear resistance is not important. Other applications include: trimming dies, extrusion dies, forging dies, die casting, forming punches, hot shear blades and mold dies.

M42 Tool Steel

 

M42 tool steel is a molybdenum high speed tool steel with 8-10% cobalt added for increased hardness and hot hardness that is superior to other high speed grades. This results in a sharper cutting edge that lasts longer, even when being used to machine high-hardness and hard-to-machine alloys in heavy duty and high production applications. M42 tool steel can be heat treated to a hardness greater than any other high speed steel and achieves the highest level of red hardness making it ideal stainless steels or any other hard to machine grades. This material has been hardened to 65-67 Rc. Typical uses include milling cutters, broaches, taps, drill bits, reamers, punches, saws, knives, and thread rolling dies. Common trade names include Braemax, CPM REX M42, Cyclops M42, Dynamax, Exocut, HS-100, Hypercut, Molite M42, Super Star, VEW S500, Uddeholm 442, Vasco Hypercut.
