H13 | SKD61 | 1.2344 | 4Cr5MoSiV1 Steel

This category belongs to chromium-molybdenum series hot work die steels, which are widely used hot work tool steels. They exhibit excellent toughness, thermal fatigue resistance, and wear resistance, along with good hardenability and tempering stability. These steels excel in manufacturing die-casting molds for aluminum, magnesium, zinc alloys, and are also suitable for hot forging dies, hot extrusion dies, and precision forging dies.

4X5MΦ1C Steel

This is a Russian hot work die steel equivalent to China's 4Cr5MoSiV1. It features good toughness and thermal strength, capable of maintaining high hardness at elevated temperatures. Applications include hot forging dies, die-casting dies, and hot extrusion dies.

X40CrMoV5-1 Steel

This is a German hot work die steel comparable to China's 4Cr5MoSiV1. It boasts high thermal strength, hardness, excellent thermal fatigue resistance, and good hardenability. It is suitable for manufacturing hot forging dies, die-casting dies, hot extrusion dies, and high-speed precision forging dies.

APPLICATION

Steel Grade	Standard Designation	Primary Applications
H13	AISI H13 (USA)	Die casting molds (Al, Mg, Zn alloys), extrusion dies, hot forging dies, plastic injection molds.
SKD61	JIS SKD61 (Japan)	Aluminum/copper alloy die casting, hot forging dies, press tools for high-temperature forming.
1.2344	DIN 1.2344 (Germany)	Hot-work tools (die casting, extrusion), high-stress components under cyclic thermal loads.
4Cr5MoSiV1	GB/T 4Cr5MoSiV1 (China)	Equivalent to H13; used for die casting, hot extrusion molds, and high-temperature precision tools.
8407	Uddeholm 8407 (Sweden)	Advanced die casting dies (Al, Mg), high-pressure molds requiring superior thermal fatigue resistance.
W302	ASTM W302 (USA)	Hot forging dies, shear blades, and tools exposed to moderate thermal shock and abrasion.
4X5MΦ1C	GOST 4X5MΦ1C (Russia)	Hot forging dies, extrusion tools, and press dies for non-ferrous metal processing.
X40CrMoV5-1	EN X40CrMoV5-1 (Europe)	High-temperature plastic molds, hot stamping tools, and components requiring wear/heat resistance.

Key Notes:

1.Thermal Fatigue Resistance: H13, SKD61, and 8407 excel in cyclic thermal stress applications (e.g., die casting).

2.Regional Standards:

USA: H13 and W302 are common for forging/extrusion.

Europe: 1.2344 (DIN) and X40CrMoV5-1 (EN) dominate high-temperature tooling.

Asia: SKD61 (Japan) and 4Cr5MoSiV1 (China) mirror H13 properties.

3.Material Compatibility: Most grades are tailored for non-ferrous metal processing (Al, Mg, Cu) due to their heat resistance (up to ~600°C).
