Understanding the Chemical Composition and Mechanical Properties of G-X120Mn12 Steel

G-X120Mn12 steel is a high manganese austenitic steel that is used in applications where high wear resistance and impact resistance are required. It is commonly used in the mining, quarrying, and construction industries.

The chemical composition of G-X120Mn12 steel is as follows:

– Carbon (C): 1.15-1.25%
– Silicon (Si): 0.40-0.80%
– Manganese (Mn): 11.50-13.50%
– Phosphorus (P): ≤0.040%
– Sulfur (S): ≤0.040%

The high manganese content provides excellent work hardening properties, which means that the steel becomes harder and stronger as it is subjected to impact or abrasive forces. This makes G-X120Mn12 steel ideal for applications that involve high-impact or abrasive conditions.

The mechanical properties of G-X120Mn12 steel include:

– Tensile strength: 680-880 MPa
– Yield strength: ≥360 MPa
– Elongation: ≥40%
– Hardness: 230-280 HBW (Brinell hardness)
– Impact toughness: ≥20 J/cm² (at room temperature)

These mechanical properties make G-X120Mn12 steel highly resistant to wear, impact, and abrasion. It has good ductility and toughness, allowing it to withstand heavy impact without fracturing or breaking.

In addition, G-X120Mn12 steel can be easily machined and welded, making it suitable for various fabrication processes. Its high work hardening ability allows for easy surface hardening techniques, such as induction hardening or work hardening.

Overall, G-X120Mn12 steel is a versatile material that offers excellent wear resistance, impact resistance, and machinability. It is commonly used in the production of wear-resistant parts, such as crusher jaws, breaker plates, and liner plates.
