Die steel and tools W1 Bars are water-hardening tool steels that can achieve high hardness after quenching because of their high carbon content, which is normally between 0.90 and 1.05%. W1 steel is mostly made of carbon and iron, with trace amounts of silicon and manganese, and has very few alloying elements. W1 steel achieves a hardness of about 60 to 65 HRC after appropriate heat treatment, providing good toughness, wear resistance, and high compressive strength. Its shock resistance and dimensional stability are inferior to those of steels that harden in air or oil, though.

Tool and Die Steel W1 bars are recyclable, reducing environmental impact. However, their production involves energy-intensive processes. Sustainable practices can enhance their eco-friendliness, such as using recycled materials and cleaner manufacturing methods.
Tool and Die Steel W1 bars are not highly resistant to corrosion, as they are high-carbon steels. They can rust when exposed to moisture, requiring proper maintenance, such as coating or regular oiling, to prevent corrosion.
Die steel and tools W1 Bars are frequently utilised in cold work tooling applications where edge retention and high hardness are crucial. Cutting tools, chisels, punches, reamers, drills, hand tools, knives, and razor blades are all made with them. Because of its exceptional machinability and capacity to retain a sharp edge, W1 is also utilised in gauges, template guides, and engraving tools. Because of its water-hardening ability, it can be used in situations where quick cooling is useful. W1 is still an affordable option for precision tools used in metal stamping, woodworking, and general toolmaking, even though it is not the best for high-temperature or high-impact settings.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
