AISI 1043 Carbon Steel Chemical Composition Properties, Grade, Table and PDF Online

AISI 1043 Carbon Steels is a medium Carbon Steels with substantial Manganese addition, which is in aid to provide these Strength and Wear resistance. Its chemical configuration is kind of 0.40-0.50% Carbon, 0.60-0.90% manganese, 0.04% phosphorus and 0.05% sulfur and so on. The properties of this steel grades include good machinability and weldability. These properties suit it for a number of industrial uses like making parts for machinery components, structural items, and shafts. Hardness is sometimes heat treated to obtain a certain effect. AISI 1043 demonstrates attributes of the USS of America such as a guaranteed consistent quality and reliability. Engineers and manufacturers, as they have access to technical tables and PDF resources which they can easily find online, most often use the precise data regarding its properties, grades, and applications.

AISI 1043 Carbon Steel Chemical Composition And Grade Table

This steel type is a medium carbon steel with chemical composition and mechanical properties, which are precisely defined, hence it makes a good candidate for various applications in the industrial sector. Alongside these, this typical chemical composition also exhibits such compounds as carbon (in the range of 0.40-0.50%), manganese (0.60-0.90%), phosphorus (0.04%) and sulfur (0.05%). Therefore, it could incorporate any amount of other elements for physical characteristics improvement. The rating features excellent workability, weldability, and ability to get into complex shapes; but the strength and hardness are at the middle level. AISI 1043 is frequently employed in making various components like cranks, bushings, screws and mechanical parts, quality of which is of the utmost importance.
