introduction

Tool Steel H13 in CNC Machining

H13 tool steel is widely used in CNC machining due to its excellent hardness, heat resistance, and toughness.

When working with H13, we consider its hardness, so we use PVD or CVD coated carbide tools with coatings for machining. We use proper cutting speeds, feeds, and coolant for optimal results. Preheat treatment before machining and post-heat treatment after machining may be necessary. We also use water-soluble coolants to help dissipate heat during machining. We adjust cutting parameters based on the machining operation and machine capabilities. We also do post-machining operations like surface finishing and heat treatment as necessary.

It's preferred for high-temperature stability applications, like hot forging and die casting. Due to its resistance to heat and wear, H13 is also adaptable for injection mold and die-casting die production. We offer H13 in different forms. Round bars and rods are for machining and forging, flat bars are for broad surfaces, plates are for larger areas like molds, and sheets are for intricate work. Square blocks suit larger tooling, and hexagonal bars are easy to handle and commonly used for precise shaping in tools and dies.

TECHNOLOGY OVERVIEW

Basic Knowledge of Tool Steel H13

What is Tool Steel H13?

Tool steel H13, also known as AISI H13 or 1.2344,  belongs to the class of high-alloy steels. It is a versatile and widely used chromium-based hot-work tool steel. It is widely used in applications involving high temperatures, such as hot forging, die casting, and extrusion.

It has high hardness, excellent heat resistance, and good wear resistance. While it offers advantages such as thermal shock and fatigue resistance, it has limitations, such as lower corrosion resistance and potential brittleness at high temperatures.

FAQ

Machining Tool Steel H13 Buying FAQ

H13 tool steel is known for its excellent corrosion resistance. It contains a significant amount of chromium, which forms a protective oxide layer on the surface of the steel. This layer helps prevent rust and corrosion. However, it's essential to properly maintain and store H13 tool steel to ensure its corrosion resistance over time.
H13 tool steel is weldable but requires careful consideration and proper welding techniques. Welding should be done using preheating and post-weld heat treatment to minimize the risk of cracking and maintain the steel's desired properties. Proper filler materials and welding procedures should also be selected to ensure a strong and durable weld.
A2 steel contains chromium, molybdenum, and vanadium, providing good wear resistance and toughness. It is often used for cold work applications, such as blanking and forming. On the other hand, H13 steel contains chromium, molybdenum, and vanadium as well but is specifically designed for hot work applications. H13 offers excellent resistance to thermal fatigue and is commonly used in die casting, forging, and extrusion applications where high temperatures are involved.
Yes, H13 tool steel is an air-hardening steel. This means it achieves hardness through cooling in air rather than oil or water quenching. The air-hardening property simplifies the heat treatment process.
