WPS is a high-carbon, high-chromium tool steel known for its excellent wear resistance, toughness, and dimensional stability. It is air-hardening, which means it achieves high hardness levels without the need for oil quenching. WPS is commonly used for cutting and forming tools, dies, and punches in applications requiring high wear resistance and dimensional stability. It is available in various grades, including D2 and D3, which offer different levels of wear resistance and toughness.
