About 300M/S155

300M/S155 is a high performance alloy steel which is a vacuum melted grade supplied in the normalised and tempered/softened condition to enhance machinability prior to final heat treatment.

It has a combination of ultra high strength, good fatigue resistance and excellent transverse properties and as such finds many applications in the aerospace industry such as undercarriage components, gears and shafts.

Alloy steels are any kind of steel to which one or more elements have been added to produce a desired characteristic or physical property. Common elements that are added to make alloy steels are molybdenum, manganese, nickel, silicon, boron, chromium, and vanadium.

FAQs & Resources

Alloy steels are any kind of steel to which one or more alloying elements have been added to produce a desired characteristic or physical property e.g. heat resistant, corrosion resistant etc. Common elements that are added to make alloy steel are molybdenum, manganese, nickel, silicon, boron, chromium, and vanadium.

Depending on the grades or added alloying elements, alloy steels can be found in high temperature applications, corrosive environment, high strength components, rotating parts and more. Some of the common components made of 300M/S155 and 4340 Alloy Steel are gears, shafts, aircraft landing gear, high strength bolts and forged hydraulic systems.
