SKD61 TOOL STEEL

SKD61 Tool Steel Supplier in China

JIS SKD61 / DIN 1.2344 / AISI H13 Hot Work Tool Steel

SKD61 tool steel is a high-performance chromium-molybdenum-vanadium hot work tool steel widely used in high-temperature tooling applications. It is especially popular in Japan, Korea, Southeast Asia, and global die casting industries due to its excellent thermal fatigue resistance, toughness, and resistance to softening at elevated temperatures.

At Hubei Risin Mould Material Co., Ltd., we supply a comprehensive range of SKD61 round bar, SKD61 flat bar, SKD61 plate, and SKD61 forged block in rolled and forged conditions.

With stable quality control, flexible processing options, and export experience, Risin provides reliable SKD61 steel solutions for:

✔Die casting molds

✔Aluminum and magnesium casting tools

✔Hot forging dies

✔Extrusion tooling

✔High-temperature mold components

Our SKD61 steel products are supplied to customers across Asia, Europe, the Americas, and other global markets.

Chemical Composition (JIS G4404 SKD61)

Risin SKD61 can also be supplied in upgraded ESR (Electroslag Remelting) quality for customers requiring higher cleanliness, improved toughness, and better polishing performance.

Key Properties

Excellent Thermal Fatigue Resistance

SKD61 is designed for repeated heating and cooling cycles.

Its excellent resistance to thermal fatigue helps reduce:

✔Heat checking

✔Surface cracking

✔Early mold failure

making it an ideal material for die casting applications.

High Temperature Strength

SKD61 maintains good mechanical properties under high-temperature working conditions.

It is widely used for:

✔Aluminum die casting dies

✔Hot extrusion tools

✔Forging dies

where conventional steels may lose strength due to heat exposure.

Outstanding Toughness

SKD61 provides an excellent balance between hardness and toughness.

It can withstand:

✔Mechanical impact

✔Thermal shock

✔High-pressure production conditions

This helps extend mold service life and improve production stability.

Good Hardenability

SKD61 offers uniform hardness after heat treatment, even for larger tooling sections.

This makes it suitable for:

✔Large die casting inserts

✔Heavy-duty tooling components

✔Precision industrial molds

Typical Working Hardness

After proper quenching and tempering:

Typical hardness: HRC 46-52

The final hardness depends on application requirements and heat treatment conditions.
