Difference between h11 and h13 – What is the difference between h11 and h13? This article will introduce the difference between them.

1. What is h11 and h13 steel?

H11 compare H13
H11 : It is relatively low in carbon content and has good toughness and deep hardens by air quench from heat treatment.
H13 : Due to its high toughness and excellent heat treatment stability, H13 can also be used in a variety of cold working tools

2. Chemical composition

3. Application

H11 is often used for highly stressed structural parts such as aircraft landing gear

H11 is common in Europe

H13Used in die casting mould, die casting sleeve, hot forging mould, extrusion mould and plastic mould cavity

H13 is the main material in the United States

According to the use condition of the mould factory, the 1.2344 more wear-resistant. Generally speaking, the service life of 1.2344 will be longer than 1.2343 in the same product, but the price almost the same, that’s why most customers prefer 1.2344, so we offer both 1.2344 and 1.2343 for your reference.

H13 application –H13 tool steels are suitable for forming extrusion dies.
H13 steel is widely used, mainly used in inserts, cores, and cavities for die casting dies, die casting shot sleeves, hot forging dies, extrusion dies, etc.

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.

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.

COMPOSITION

Characteristic

H13 steel is the most widely used and most representative hot work die steel. Its main characteristics are as below:

(1) has high hardenability and high toughness;

(2) Excellent resistance to thermal cracking, which can be water-cooled in the workplace;

(3) It has medium abrasion resistance, and can also be used to improve the surface hardness of carburizing or nitriding process, but slightly reduce the resistance to thermal cracking;

(4) Because of its low carbon content, the secondary hardening ability in tempering is poor;

(5) It has softening resistance at higher temperatures, but the hardness is higher than 540 °C (1000 °F), and the hardness is rapidly decreased (ie, the working temperature is 540 °C);

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.

H13 Application

Inserts, cores, and cavities for die casting dies, die casting shot sleeves, hot forging dies, extrusion dies, and plastic mold cavities and components that require high toughness and excellent polishability.

8620 Material description

AISI 8620 is a type of alloy steel, 8620 Material is a case-hardening steel containing nickel, chromium, and molybdenum as alloying elements.
These ingredient elements must be within certain weight percentages to create the 8620 alloys. It takes advantages of good strength and toughness properties and has a higher core strength than grades 8615 and 8617. The equivalent Chinese material of AISI 8620 alloy steel is 20CrNiMo, which is a common material grade in steel forging.
The alloy shows good strength and toughness properties. This alloy may be used in the production of medium-strength parts such as forged camshafts, fasteners, and gears. Extensive surface carving is not ideal for 8620, however, it responds well to polishing.

8620 Material Chemical Composition

Heat Treatment of 8620 Material

1.Annealing: For optimum machinability, an as-forged structure is normally sufficient for this grade of alloy steel. If this proves not to be the case then an iso-anneal from around 1650ºF (900ºC) to 1225ºF (660ºC) will improve machinability.

2.Normalizing: 1675ºF (910ºC) and air cool. This is another method of improving machinability in this grade; normalizing might also be used prior to case hardening.

3.Hardening: The alloy will be austenitized at around 1525ºF (830ºC) and oil or water quenched depending upon section size and intricacy.

4.Tempering: To desired hardness, using temperatures based on past experience, following water or oil quench.

5.Machinability: This grade of alloy is readily machined following suitable cooling from forging or subsequent heat treatment.

6.Weldability: This steel may be welded by normal fusion methods, but prior to carburizing or hardening and tempering.

Application of AISI 8620 Material

AISI 8620 steel forging material is used extensively by all industry sectors for light to medium stressed components and shafts requiring high surface wear resistance with reasonable core strength and impact properties.

Typical applications are: Arbors, Bearings, Bushings, Cam Shafts, Differential Pinions, Guide Pins, King Pins, Pistons Pins, Gears, Splined Shafts, Ratchets, Sleeves and other applications where it is helpful to have a steel that can be readily machined and carburized to controlled case depths.
