The AISI (American Iron and Steel Institute) classification system includes several grades of hot work tool and die steels. These grades are designated with a prefix “H” followed by a number. Here are some common AISI grades of hot work tool and die steels:
AISI H13: This is one of the most widely used hot work tool steel grades. It is known for its excellent combination of high-temperature strength, wear resistance, and toughness. AISI H13 is commonly used for die casting dies, extrusion dies, and hot forging dies.
AISI H11: AISI H11 is another hot work tool steel with good high-temperature strength and resistance to thermal fatigue. It is used in applications such as forging dies and extrusion tools.
AISI H21: AISI H21 is a tungsten-containing hot work tool steel known for its high-temperature strength and excellent heat resistance. It is used in applications involving high-temperature tooling, such as die casting and hot extrusion.
AISI H19: AISI H19 is a chromium-molybdenum hot work tool steel with good heat resistance and wear resistance. It is often used for hot forging dies and extrusion tools.
AISI H10: AISI H10 is a hot work tool steel with good high-temperature strength and toughness. It is used in applications such as die casting dies and hot forging dies.
AISI H12: AISI H12 is a chromium-molybdenum-vanadium hot work tool steel known for its high-temperature strength and resistance to thermal fatigue. It is used in applications involving hot stamping and hot forging.
AISI H14: AISI H14 is a tungsten-containing hot work tool steel known for its high-temperature strength and good heat resistance. It is used in applications such as die casting and hot extrusion.
These are some examples of AISI hot work tool and die steel grades. Each grade has its own unique combination of properties, making it suitable for specific high-temperature applications. When selecting a hot work tool steel grade, factors such as temperature resistance, wear resistance, toughness, and machinability must be considered based on the requirements of the tool or die application.
Various countries and regions have their own classification systems and designations for hot work tool and die steels, which may differ from the AISI (American Iron and Steel Institute) system commonly used in North America.
These classification systems are established by national or international standards organizations to categorize and specify tool and die steels based on their composition and properties. Here are some examples of such systems used in different countries:
DIN (Deutsches Institut für Normung – German Institute for Standardization): Germany uses the DIN system to classify hot work tool and die steels. For instance, “DIN 1.2344” is a widely used hot work tool steel known as H13 in the AISI system.
JIS (Japanese Industrial Standards): Japan uses the JIS system to designate hot work tool and die steels with alphanumeric codes. For example, “JIS SKD61” is equivalent to AISI H13.
ISO (International Organization for Standardization): ISO has international standards for tool steels, including hot work tool and die steels. An example is “ISO 4957 1.2344,” which is equivalent to AISI H13.
BS (British Standards): The British Standards Institution (BSI) uses its own system for categorizing tool steels. For instance, “BS 4659 BH13” is equivalent to AISI H13.
EN (European Norm): In Europe, hot work tool and die steels are often designated using EN standards. For example, “EN ISO 4957 1.2344” corresponds to AISI H13.
GB (Guobiao – Chinese National Standards): China uses the GB standard system to classify tool steels. For instance, “GB/T 1299 4Cr5MoSiV1” is equivalent to AISI H13.
The choice of classification system often depends on regional standards and industry practices. When working with hot work tool and die steels, it’s crucial to refer to the relevant standards and specifications to understand the properties and characteristics of a particular grade, regardless of the naming convention used.
Hot work tool and die steels are designed to withstand elevated temperatures and thermal stresses encountered in high-temperature applications such as hot forging, die casting, and extrusion.
These steels maintain their hardness, strength, and toughness even at high temperatures. Hot work tool and die steels are categorized differently in the AISI (American Iron and Steel Institute) system, commonly used in North America, and the DIN (Deutsches Institut für Normung – German Institute for Standardization) system, commonly used in Germany.
Here are some common hot work tool and die steel grades with their equivalents in both systems:
AISI and DIN Hot Work Tool and Die Steel Grades:
AISI H13 (DIN 1.2344): AISI H13 is a widely used chromium-molybdenum hot work tool steel known for its high temperature strength, resistance to thermal fatigue, and good toughness. It is commonly used for applications like die casting and extrusion dies.
AISI H11 (DIN 1.2343): AISI H11 is a chromium-molybdenum hot work tool steel with good resistance to thermal shock and thermal fatigue. It is used for applications that require high-temperature strength and toughness.
