Chemical composition:

Features:
1.2714, originates from SUPER technology and is a type of hot work tool steel with high quality. Its main features includes high purity, homogeneous annealing structure, excellent impact property.
1.2714 is applied for making hot extrusion die, hot forging die and large-sized plastic mould which has high demand on toughness, and also need polishing or dermatoglyph treatment.
1.2714 is strictly inspected as per standard NADCA#207-2011, and other properties also can be tested as customers' requirement.

Characteristics
Hot work tool steel featuring a fine combination of heat checking resistance, hot strength and impact strength; admits water cooling.
 
Applications
1. Highly stressed hot work tools, mainly for the processing of heavy alloys, such as mandrels, dies
and containers for metal tube and rod extrusion; hot extrusion tools;
2. Tools for the manufacture of hollows, screws, rivets, nuts and bolts.
3. Die casting tools, forming dies, die inserts, hot shear blades.
4. Forging tools, dies of all sorts, shapes and sizes, hot forging and pressing tools for steel and metal. Moulds, bushings, piercers etc. 

Soft Annealing
Heat to 650-700^oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 248.

Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to 650^oC, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.

Hardening
Oil: Harden from a temperature of 830-870^oC followed by oil quenching. Hardness after quenching is 58 HRC.
Air: Harden from a temperature of 830-900^oC followed by air quenching. Hardness after quenching is 56 HRC. 

Tempering
Tempering temperature: See the data bellow.

Quenching in oil:
Tempering Temperature (^oC) vs. Hardness (HRC)vvs. Hardness (HRC) vs. Tensile Stregth (N/mm²)

Quenching in air:
Tempering Temperature (^oC) vs. Hardness (HRC) vs. Hardness (HRC) vs. Tensile Stregth (N/mm²)

Forging
Hot forming temperature: 1050-850^oC. 

Machinability
The machinability rating of D3 is roughly 25 % that of free machining carbon steel 1018. Due to its abrasion resistant nature, machining in the hardened condition should be limited to finish grinding.

Delivery Condition
EAF+LF+VD+(ESR), Hot rolled or Forged, Annealed, EFS, Hardness≤235HB, Un-machined or
Machined surface (Peeled, Turned, Milled, Grinded), UT 100% Passed
 

Heat Treatment
Annealing
750 to 800°C (1382 to 1472°F)
Slow controlled cooling in furnace at a rate of 10 to 20°C/hr (50 to 68°F/hr) down to approx. 600°C (1112°F), further cooling in air. Hardness after annealing: max. 235 HB.
           
Stress relieving
600 to 650°C (1112 to 1202°F)
Slow cooling in furnace; intended to relieve stresses set up by extensive machining, or in complex shapes. After through heating, hold in neutral atmosphere for 1 - 2 hours.
 
Hardening
1010 to 1050°C (1850 to 1922°F)
Oil, salt bath (500 - 550°C / 932-1022°F), air
Holding time after temperature equalization: 15 to 30 minutes.
Obtainable hardness: 52 - 56 HRC
 
Tempering
Slow heating to tempering temperature immediately after hardening / time in furnace 1 hour for each 20 mm of work piece thickness, but at least 2 hours / cooling in air. It is recommended to temper at least twice. A third tempering cycle for the purpose of stress relieving may be advantageous. 
1st tempering approx. 30°C (86°F) above maximum secondary hardness.
2nd tempering to desired working hardness. The tempering chart shows average tempered hardness values. 
3rd for stress relieving at a temperature 30 - 50°C (86 to 122°F) be low highest tempering temperature.
