What is T45Cr5Si3 grade steel?
T45Cr5Si3 is Alloyed Cold Work Tool Steels acc. to IS 1570-6-96, High strength, good toughness, good hardenability, good stability against overheating, Used in the manufacture of medium-speed, heavy-duty, high-strength, high-toughness parts and high-strength components. It is mostly used to manufacture various important parts with high load and high speed, such as gears, shafts, clutches, sprockets, grinding wheel shafts, bushings, bolts, nuts, etc. It is also used to manufacture parts with wear resistance and low working temperature, variable load Welded components such as high-pressure blower blades, valve plates, and non-corrosive pipes. welding and riveting structural parts working under vibration load, such as high-pressure blower blades, valve plates and high-speed and high-load shafts, gears, sprockets, clutches, bushings, bolts, nuts, etc.
