AISI 4815 Alloy Steel Chemical Composition & Properties, Grade, Table and Document
The AISI 4815 alloy steel stands out among other low-carbon nickel-chromium-molybdenum steels because of its extended range of hardenability and shock resistance. Composed of 0.8 to 1.1% carbon, 1.45 to 1.95% manganese, 0.4 to 0.75% chromium, and 0.2 to 0.35% molybdenum, it has high levels of overall strength and shows good wear resistance. Stainless steel AISI 4815 overruns with maximum wear fatigue stress and impact endurance, which is used in gears, shafts and other gear parts. Such characteristics as high hardenability as well as a good machinability at normalized and annealed conditions have also been proved. Moreover, the material provides some welding advantages too. Furthermore, it matches both ASTM A29 and ASTM A322 standards. Therefore, AISI 4815 perfectly fits the bill. The composition, properties, grade, and accompanying documentation of steel including the specification sheets and standards are clear and readily provided by the manufacturers and industry standards organization
AISI 4815 Alloy Steel Chemical Composition And Grade Table
AISI 4815, which is a low alloy steel, is highly popular due to its outstanding combination of tensile properties and toughness. Its chemical profile is usually filled by carbon, manganese, silicon, sulfur, phosphorus, chromium, nickel, molybdenum, and vanadium, in most cases. The table of grade AISI 4815 provides the evidence of it being appropriate to exploit in machining processes, where the requirements are for the high strength and resistance to fatigue and wear. With a combination of alloying elements, this super-alloy exhibits excellent hardenability and machinability which have made it a top material necessary in various industries like automotive, aerospace, and machinery for which performance and dependability are critical.
