Bars and rods of high-speed steel

cpc code 41271 covers the production of bars and rods made from high-speed steel, a specialized alloy steel known for its exceptional hardness, strength, and ability to retain its cutting edge at high temperatures. This industry plays a crucial role in the manufacturing sector, providing essential raw materials for the production of cutting tools, machine parts, and other industrial applications that require durable, high-performance materials.

The production of high-speed steel bars and rods typically involves a multi-step process. First, the raw materials, including iron, tungsten, chromium, and other alloying elements, are melted and combined in a furnace. The molten steel is then cast into ingots or continuously cast into billets or bars. These semi-finished products are then subjected to a series of hot-working processes, such as rolling or forging, to shape them into the desired dimensions and profiles. Finally, the bars and rods may undergo heat treatment, such as quenching and tempering, to enhance their mechanical properties.

The main inputs required for the production of high-speed steel bars and rods include iron ore, alloying elements (such as tungsten, chromium, and vanadium), and specialized equipment like electric arc furnaces, rolling mills, and heat treatment facilities. Additionally, the industry relies on skilled labor, energy sources, and transportation infrastructure to support the manufacturing and distribution of these products.

The primary output of this industry is high-speed steel bars and rods, which are then consumed by various downstream industries. These include the 41272 Cutting tools and machine tool accessories industry, which uses high-speed steel to manufacture cutting tools, drill bits, and other industrial tools. The 41273 Metalworking machinery industry also utilizes high-speed steel components in the production of machine tools and related equipment.
