AISI 1572 Uses

SAE/AISI 1572 is an alloy that has many practical uses in the manufacturing and machining industries. It is often used for making cutting tools such as drills, saw blades, reamers, taps, dies and files. The hardness and strength of this alloy also make it ideal for use in high-wear parts such as gears, shafts and bearings. In addition to these applications, it can also be used to make highly durable moulds for casting metals and plastics.

Corrosion Resistance

Corrosion resistance is another important property that makes SAE/AISI 1572 a versatile alloy. Its low chromium content prevents oxidation from occurring on the surface when exposed to air or water. This makes it resistant to rusting and corrosion even in environments with high humidity or saltwater exposure levels. As such, it can be used in many maritime applications where other materials may not be suitable.

Heat Resistance

Like any metal alloy, SAE/AISI 1572 has a melting point that must be taken into consideration when using it in applications where high temperatures are present. The melting point for this particular alloy is around 2200°F (1205°C). Although this temperature is still below that of some other common alloys, such as stainless steel or titanium alloys, it is still important to limit exposure time at high temperatures so as not to permanently damage the structure or integrity of the material itself.

Heat Treatment

In order to maximize its performance characteristics, such as hardness and strength, while minimizing brittleness or risk of fracture during use under load conditions, heat treatment processes are often required after manufacturing parts from this alloy. Heat treatment involves subjecting the part to specific temperatures over a set amount of time before cooling it down slowly to complete the process. Depending on the desired outcome, different methods can be utilized, including normalizing (slow cooling), quenching (rapid cooling) or tempering (controlled cooling).


Due to its relatively hard structure compared to some other alloys available on the market today, machining parts from this material requires more precise equipment than standard machines used for softer materials like aluminium or copper alloys. Speciality tools, such as reamers, drills, taps, end mills, etc., are generally needed in order to achieve smooth finishes without damaging the workpiece. Additionally, higher speeds may be necessary compared with other materials due to their increased hardness which can cause excessive wear if not monitored properly during operation.


Welding operations with this material require extra caution due to its hard structure, which can create difficulties when attempting fusion welds between two pieces. The best option for welding this material is TIG welding which offers superior control over heat input during welding compared with MIG welding, which could potentially lead to cracking if not done properly. Additionally, proper preheating prior to welding should always be done prior in order to ensure proper adhesion between both pieces being joined together.


Overall, SAE/AISI1572 offers superior wear resistance combined with good corrosion protection, making it ideal for many industrial applications requiring long service life while maintaining structural integrity over time. From cutting tools, shafts & bearings, moulds & dies – there are multiple ways manufacturers can take advantage of this material’s unique properties depending on their end goals & objectives. With proper care & maintenance throughout the fabrication & post-fabrication processes, manufacturers can enjoy consistent quality products produced from this tough yet malleable metal alloy.​
