W18Cr4V Round Bar

W18Cr4V is a quintessential tungsten-type high-speed tool steel (also known as high-speed steel/white steel). Its main composition includes approximately 18% tungsten and 4% chromium, with an appropriate amount of vanadium. It possesses high hardness, high hot hardness (hardness at high temperatures), and excellent wear resistance, making it highly suitable for manufacturing cutting tools (such as drill bits and milling cutters) and molds. It maintains its hardness even at high temperatures, exhibits excellent cutting performance, and is easy to grind and machine.

Key Characteristics

• Composition: W (Tungsten) 18%, Cr (Chromium) 4%, V (Vanadium) appropriate amount.

• Hardness: High hardness after quenching; maintains high hardness levels of HRC 63-64 at 500℃ (approx. 932°F) and HRC 62-63 at 600℃ (approx. 1112°F).

• Hot Hardness: Features outstanding high-temperature hardness and hot hardness, with strong cutting ability at high temperatures.

• Wear Resistance: Excellent wear resistance and good edge retention.

• Machinability: Wide heat treatment range, less prone to overheating, oxidation, and decarburization, with good grinding performance.

Application Fields

• Various high-speed cutting tools (drill bits, milling cutters, turning tools, threading tools, etc.).

• Molds requiring high wear resistance.

• Machining difficult-to-cut materials like stainless steel and alloy steel.

Variant

• W18Cr4VCo5: Addition of cobalt (Co) further enhances impact resistance and high-temperature performance.

W18Cr4V is a widely used, high-performance tool steel in industry, renowned for its excellent performance under high temperatures and heavy loads. It is an ideal material for manufacturing high-efficiency, long-life cutting tools‌‌
