Comprehensive range of tool steels and precision-engineered components for industrial applications.

Cold Work Steel

Highly wear-resistant steels used in low to medium temperature applications. Includes water hardening, oil hardening, air hardening, high carbon-chromium, and shock-resisting types.

Grades: D2 (1.2379), O1 (1.2510), A8 Mod.
Forms: Round Bar, Flat Bar, Block, Sheets
Applications: Punch molds, cutting tools

Hot Work Steel

Designed for high-temperature environments with excellent resistance to softening, heat checking, and shock. Ideal for die casting and forging applications.

Key Grade: H13 (1.2344)
Properties: High heat resistance, medium wear resistance
Low distortion during hardening

High Speed Steel (HSS)

Most highly alloyed tool steel type, capable of maintaining sharp cutting edges at elevated temperatures during heavy cuts and high-speed operations.

Resists softening at high temperatures
Ideal for drills, milling cutters, saw blades
Available in round, flat, and blank forms

Plastic Mould Steel

Low carbon content (0.36–0.40%) with chromium and nickel as main alloying elements. Enables extremely high polish finish for precision molds.

Excellent machinability and polishability
Corrosion-resistant properties
Used in injection molding and extrusion dies

Stainless Steel

Martensitic stainless steel with 0.1–1.0% C and 12–27% Cr. Enhanced with molybdenum, tungsten, vanadium, and niobium for superior performance.

High strength and corrosion resistance
Heat treatable for hardness optimization
Suitable for cutting tools and shafts

HSS Circular Saw Blades

High-performance saw blades with TiCN coating for increased hardness, reduced friction, and improved wear resistance and anti-adhesion.

TiCN multilayer coating

Frequently Asked Questions

What is the difference between cold work and hot work tool steel?

Cold work steels are used at low to medium temperatures and offer high wear resistance. Hot work steels are designed for high-temperature applications, providing resistance to softening, heat checking, and thermal shock.

Why choose H13 tool steel?

H13 (1.2344) is one of the most popular hot work steels due to its excellent combination of toughness, thermal fatigue resistance, and machinability. It's widely used in die casting, forging, and extrusion dies.

What are the advantages of TiCN coating on HSS saw blades?

TiCN coating provides higher hardness, lower friction coefficient, better wear resistance, and anti-adhesion properties. This results in faster sawing speeds and extended blade life.

Can you customize tool steel dimensions?

Yes, we offer customization of grades, sizes, and forms including round bar, flat bar, block, sheets, and semi-finished blanks according to customer specifications.

Do you provide technical support?

Yes, we offer comprehensive technical support including material selection guidance, heat treatment recommendations, and application engineering to optimize performance.
