AISI H10 /din 1.2365 32CrMoV12-28 h10 jis skd7 steel bar

1.2365 steel is a type of steel that is commonly used in the manufacturing of hot extrusion dies, hot stamping dies, hot forging dies, and plastic extrusion dies. This type of steel is primarily used in the production of aluminum alloy die casting dies.

The chemical components of 1.2365 steel include 4Cr3Mo3SiV, which is known for its strength and durability in high-temperature applications. This steel also has high toughness and wear resistance, making it ideal for use in high-stress environments.

The use of 1.2365 steel in die manufacturing ensures that dies are durable and can withstand high temperatures and stresses. This, in turn, contributes to the production of high-quality products in industries such as automotive, aerospace, and industrial manufacturing.

The chemical components of 1.2365 steel include:

- Carbon (C): 0.30%-0.35%
- Silicon (Si): 0.80%-1.20%
- Manganese (Mn): 0.20%-0.50%
- Chromium (Cr): 2.80%-3.40%
- Molybdenum (Mo): 1.10%-1.50%
- vanadium (V): 0.25%-0.35%

►1.2365 Steel, also known as 4Cr3Mo3SiV (H10) Steel, is a steel alloy with a carbon content and mass fraction of 0.4%, and a mass fraction of approximately 3% for Cr and Mo. It contains a high proportion of carbide-forming elements such as Cr, Mo and V, which give it excellent properties such as high hardness, thermal strength and wear resistance at working temperatures of 500-600℃.

► H10 steel is its excellent hardenability and toughness, with its tempering performance and thermal stability surpassing that of H13 steel. Its impact toughness and fracture toughness are also superior to that of 3Cr2W8V steel. In fact, when tempered at a temperature over 260℃, the hardness of the steel is greater than that of H13 steel.

►The combination of high strength, excellent toughness and superior hardness makes 1.2365 Steel an ideal material for use in various industrial tools, such as extrusion tools, die-casting tools, forging dies, hot shear knives and stamping dies. This steel is also highly valued in the automotive and aerospace industries, where it is used for manufacturing engine parts and components.

►4Cr3Mo3SiV (H10) steel can manufacture hot extrusion die, hot stamping die, hot forging die and plastic extrusion die, mainly used for aluminum alloy die casting die.
