AISI 4161 Alloy Steel Chemical Composition Properties, Grades, Table and PDF Online
AISI 4161 steel is a low-alloy metal that is highly praised for its high strength and ultimate toughness. Its chemical composition has those elements like carbon, manganese, silicon, sulfur, phosphorus, chromium, molybdenum and nickel and these element contribute to the great mechanical properties. Tougher and with endurance, AISI 4161 is specially designed for automotive, aerospace, or machinery industries with the purpose of product design, particularly involving heavy weight structures. It is this hybrid of steel alloy which gives excellent service in anticorrosive environment and as well can take high heat, which is why it is useful in heavy duty conditions. AISI 4161 grades may be divided based on manufacturing standard grades or specific requirements of customers. Adding a specification table, chart and pdf resources will give more information about the recent productions, structure, properties and its application which can be taken into account by engineers and manufacturers in material selection and design improvement.
AISI 4161 Alloy Steel Chemical Composition And Grade Table
AISI 4161 alloy steel is another term for a low alloy steel, famous for its superior strength and durability. Chemically, it is composed of elements: carbon, manganese, and silicon, but also: chromium, molybdenum, and nickel. In terms of exact ingredients, they could have slight differences that would be specified by the manufacturer, but compositions probably contain approximately 0.15 – 0.20% carbon, 0.60 – 0.90% manganese, 0.15 – 0.35% silicon, 0.80 – 1.10% chromium, 0.1 Having a balanced composition, AISI 4161 shall provide high hardenability, wear resistance and toughness, thus allowing the use of this steel in the various fields such as automotive, aerospace or machinery manufacturing.
