ASTM A335 Gr.P11 is equivalent to domestic high-speed steel. Speed steel has good process performance, good strength and toughness, so it is mainly used to manufacture complex thin-edged and impact-resistant metal cutting tools, as well as high-temperature bearings and cold extrusion dies.
In addition to the high-speed steel produced by the smelting method, powder metallurgy high-speed steel appeared after the 1960s, which has the advantage of avoiding the reduction of mechanical properties and heat treatment deformation caused by the segregation of carbides produced by the smelting method. High-speed steel is a kind of alloy steel with complex composition, which contains carbide-forming elements such as tungsten, molybdenum, chromium, vanadium, and cobalt. The total amount of alloying elements is about 10 to 25%. It can still maintain high hardness under high heat generated by high-speed cutting (about 500 ℃), and the HRC can be above 60. The most important characteristic of high-speed steel is red hardness, while carbon tool steel has high hardness at room temperature after quenching and low-temperature tempering, but when the temperature is higher than 200 ℃, the hardness drops sharply, at 500 ℃ The hardness has dropped to a level similar to the annealed state, completely losing the ability to cut metal. This limits the use of carbon tool steel to make cutting tools. Due to its good red hardness, high-speed steel makes up for the fatal shortcomings of carbon tool steel and can be used to manufacture cutting tools.

Alloy Steel pipes have hollow sections and are widely used as pipelines for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, alloy steel tube is lighter in weight when the bending and torsional strength is the same. Alloy steel pipe is an economical section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile transmission Axles, bicycle racks and steel scaffolding used in building construction, etc.
