In contrast of the AISI 1146 which is a medium carbon steel, it is commonly used due to its good machinability as well as wear resistant features. The carbon content in level A has a range of 0.43% to 0.50%, thus this level delivers good strength, but may slightly lack toughness. With HSLA designation this steel is employed in areas that require for instance strong gears, shafts and components of machinery. AISI 1146 may be heat-treated to customize the properties the mechanical strength it offers. Such AISI 1146 grades can be incorporated through heat treatment and chemically varied on the type of products the client demands. The information concerning the chemical properties with their corresponding grades is published on the internet as a table and chart in PDF format which assists engineers and manufacturers in material selection and processing.
AISI 1146 is a carbon-low steel range that is predominantly used for structural purposes. Its composition, which is the chemical one and frequently includes carbon, manganese, phosphorus, sulfur and traces of other elements, is another important characteristic feature. Composition may be the particular blend which is made keeping in mind process of manufacturing and properties of the material that are to be achieved From the point of view of ratings, AISI 1146 belongs to the group of alloys based on carbon and the strength properties of this steel are reflected in its service. It shows well weldability and machinability, therefore it can be widely used in the area of manufacturing products which require high strength and durability.

Advantages:
High strength: Better strength properties compared to other carbon steels.
Good impact resistance: Suitable for quick impacts or forces.
Moderate machinability: Can be machined with appropriate tools and methods.
Fair weldability: Can be welded with proper precautions.
Disadvantages:
Limited corrosion resistance: Prone to rust and corrosion.
Not easily heat treatable: Restricted in practical use of heat treatment.
Potential for distortion: May get deformed during machining or heat treatment.
Moderate wear resistance: May not be as durable as harder steel in abrasive conditions.
