өзгөчөлүктөрү

H13 Tool Steel is a versatile chromium-molybdenum hot work steel that is widely used in hot work and cold work tooling applications. 

The hot hardness (hot strength) of H13 resists thermal fatigue cracking which occurs as a result of cyclic heating and cooling cycles in 

hot work tooling applications. Because of its excellent combination of high toughness and resistance to thermal fatigue cracking 

(also known as heat checking) H13 is used for more hot work tooling applications than any other tool steel.

Because of its high toughness and very good stability in heat treatment, H13 is also used in a variety of cold work tooling applications. 

In these applications, H13 provides better hardenability (through hardening in large section thicknesses) and better wear resistance than 

common alloy steels such as 4140.

Алдын ала ысытуу: To minimize distortion in complex tools use a double preheat. Heat at a rate not exceeding 400°F per hour (222°C per hour) to 1150-1250°F (621-677°C), equalize, then raise to 1500-1600°F (816-871°C) and equalize. For normal tools, use only the second temperature range as a single preheating treatment.


Аустениттөө (жогорку жылуулук): Heat rapidly from the preheat. Furnace or Salt: 1800-1890°F (982-1032°C) For maximum toughness, use 1800°F (982°C) For maximum hardness and resistance to thermal fatigue cracking and wear use 1890 (1032°C). Soak at temperature for 30 to 90 minutes.


Өчүрүү: Air, pressurized gas, or warm oil. Section thicknesses up to and including 5 inches (127 mm) will typically fully through harden when cooled in still air from the austenitizing treatment. Sections greater than 5 inches (127 mm) in thickness will require accelerated cooling by using forced air, pressurized gas, or an interrupted oil quench to obtain maximum hardness, toughness and resistance to thermal fatigue cracking.

For pressurized gas quenching, a minimum quench rate of approximately 50°F per minute (28°C per minute) to below 1000°F (538°C) is required to obtain the optimum properties in the steel.

For oil, quench until black, about 900°F (482°C), then cool in still air to 150-125°F (66-51°C).


артыкчылыгы:

1.High hardenability and toughness

2.Great resistance for thermal cracking

3.The secondary hardening ability in tempering is bad due to its lower carbon content

4.The deformation is small after heat treatment

5.Good machinability.
