Alloy Tool Bar D2/H13/P20 Forged Steel Round Bar

Round steel is a kind of hollow cylindrical metal material, which is widely used in construction, machinery manufacturing, automobile manufacturing, energy, transportation and other industries. Round steel is mainly made of carbon steel, alloy steel and tool steel. Among them, carbon steel round steel refers to steel with carbon content within the range of 0.20% to 0.55%. Carbon steel round steel is an economical and practical structural material with good weldability, plasticity and machinability. Alloy steel round steel refers to the steel with a certain amount of alloying elements (chromium, manganese, cobalt, boron, molybdenum, vanadium, etc.), which can obtain higher strength, hardness, corrosion resistance and wear resistance. Tool steel Round steel is a kind of high-speed tool steel material, which has the advantages of high hardness, high red hardness and wear resistance. Product Description Steel Grade Q195, Q235,…
