AISI 5147 Alloy Steel Chemical Composition & Properties, Grades, Table and Pdf

The AISI 5147 is a precise alloy developed with a purpose of blowing out the competition in terms of strength and longevity. Like other metals, its chemical composition usually consists of carbon, manganese, silicon, chromium, and molybdenum explaining the satisfactory mechanical performance of the alloy. Thanks to the high yield stress and good hardenability, it is widely applied in cases where parts have to be resilient, like gears, shafts, and crankshafts. They may be different slightly in details and features if they undergo different manufacturing process and grades, though. Table or a chart and pdf that enumerates all the available grades and their constituents, mechanical capabilities & feasible areas of deployment is another good option that might be used to present information in this respect. It is of the utmost importance to know these facts for choosing the right grade of AISI 5147 alloy steel for an engineering or industrial applications.

AISI 5147 Alloy Steel Chemical Composition And Grade Table

AISI 5147 is alloy steel that is famous in the industry for its superior strength and hardness. Apart from carbon, manganese, silicon, chromium and molybdenum are other elements that its chemical formulation may contain. While the exact proportion may differ from one producer to the next or from one industry to the other, it will still contain these four primary components. For making of grades, AISI 5147 is accommodated within the SAE-AISI designation system and is widely used as the low-alloy steel. It is good for workability and welding. Therefore, it is suitable for many applications in industries like automobile sector, aviation and machinery manufacturing.

Advantages and Disadvantages of AISI 5147 Alloy Steel


  • High Hardenability: A variation in mechanical properties, particularly high hone harden ability that provides the material with good strength and wear properties on heat treatment.

  • Superior Fatigue Resistance: Has higher fatigue strength than some other alloy steels and therefore ideal for use in condition that ensue cyclic loading.

  • Good Machinability: Excellent machinability properties, this makes it possible to perform fabrications and machining operations with a lot of ease.

  • Wear Resistance: Demonstrates good wear resistance characteristics and thus makes it possible to enhance durability in usage on equipment that is exposed to abrasive wear.


  • Cost: Although the excellent properties and specific alloying elements make this type can be quite expensive as presented in the case of affordability for particular use.

  • Corrosion Susceptibility: Innately prone to corrosion when used in their unprotected state, and must therefore receive the appropriate surface finishing.

  • Weldability Issues: As with the rest of the alloy steels, some difficulties in welding may arise and are therefore best approached with care and expertise.

  • Limited Availability: May be available in a limited range than other standard SV steel types hence the issues of availability and lead time when ordering from the market.
