AISI 4620 Alloy Steel Chemical Composition & Properties, Grade, Charts and Pdf
AISI 4620 alloy steel which nickel, chromium and molybdenum composed outstanding toughness and strength is recognized. Its chemical structure is generally carbon, manganese, silicon, phosphorus, sulfur, chromium, nickel, and molybdenum, which are the common ingredients. Vanadium is sometimes added to the list. Its moderate hardenability makes it suitable for heat treating with cooked shapes. This property can ensure a proper machining and welding of treated metal. AISI 4620 is applied in gears, axles, crankshafts, and other components under high-stress machinery industry environments besides in automotive industry. The material features characteristics like high tensile strength, great fatigue resistance that were created to be used for long durations of time and good wear resistance. Detailed charts and PDF documents can be downloaded that provide detailed information such as its composition, mechanical properties, heat treatment step by step and more which will help engineers and metallurgists greatly in selecting the proper material and designing application.
AISI 4620 Alloy Steel Chemical Composition And Grade Table
AISI 4620, a low carbon steel with high nickel-molybdenum alloy is an excellent example of very tough alloy with superior hardenability. It is usually chemically built up from about 1.8-2.5% of carbon (C) and max. 0.7-0.9% of manganese (Mn), whereas phosphorus (P) is at the most 0.01%.0.040%, sulfur (S) max. 0.The list of major constituent elements includes iron (Fe) represented at 0.34-0.75%, silicon (Si) at 0.15-0.35%, chromium (Cr) at 0.40-0.60%, molybdenum (Mo) at 0.20-0.30%, and nickel (Ni) at 1. Because of hardness levels from 170 to 217, HBW 4620 is often used in gears, crankshafts, as well as other heavy equipment components providing good wear out and strength.
