Rupal Metals stands out as a reputable manufacturer and supplier of Tool and Die Steel W1 Bars, proudly based in Delhi, India. They’re recognized for delivering top-notch tool steel solutions across various industries. W1 is a water-hardening tool steel that boasts impressive hardness and machinability, making it a go-to option for general-purpose tooling. Rupal Metals offers W1 bars in a range of sizes and specifications, customized to fit the needs of clients in sectors that demand precision and durability. With a commitment to consistent material quality, quick processing, and a robust distribution network, Rupal Metals guarantees reliable service and exceptional performance in applications that require sharp edges and moderate wear resistance.
Tool Steel W1 Bars are mainly made up of high carbon content (0.90–1.10%) along with trace amounts of Manganese (0.25–0.50%) and Silicon (0.10–0.40%). This straightforward carbon steel achieves a remarkable level of hardness after water quenching, typically hitting 60–66 HRC. W1 also features high tensile strength and outstanding edge-holding ability. Since it’s not alloyed with chromium or vanadium, it’s more cost-effective and easier to machine. However, it does have lower toughness compared to alloyed tool steels, making it best suited for applications that require high hardness but have limited shock resistance.

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.
Tool and Die Steel W1 Bars find extensive use in general-purpose tools where high surface hardness and sharp cutting edges are essential. You’ll often see them in drill bits, reamers, cutters, hand tools, knives, and chisels. W1 is also utilized for dies, taps, and lathe tools in small to medium production settings. Its excellent machinability and hardenability make it ideal for applications that need fine edges and moderate wear resistance. However, due to its lower toughness, it’s best used in situations with minimal shock or impact loading, making it a favored choice for affordable, precision cutting and shaping tools.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
