1. Carbon (C): It is the main element that provides strength to the steel. The carbon content in GTS-55 steel grade is usually between 0.50% and 0.60%.

2. Manganese (Mn): It helps in enhancing the hardenability and tensile strength of the steel. The manganese content in GTS-55 steel grade is typically around 1.00%-1.40%.

3. Silicon (Si): It helps in improving the steel’s resistance to corrosion and oxidation. The silicon content in GTS-55 steel grade is generally between 0.20% and 0.40%.

4. Chromium (Cr): It contributes to the steel’s hardness and resistance against wear and corrosion. The chromium content in GTS-55 steel grade is usually around 0.80% to 1.10%.

5. Nickel (Ni): It enhances the steel’s toughness and resistance to corrosion. The nickel content in GTS-55 steel grade is typically between 1.50% and 2.00%.

6. Molybdenum (Mo): It improves the steel’s strength, hardness, and overall toughness. The molybdenum content in GTS-55 steel grade is generally around 0.30%-0.60%.

Mechanical Properties:
The mechanical properties of GTS-55 steel grade are as follows:

1. Tensile Strength: GTS-55 steel grade has a high tensile strength of around 1000 MPa, making it suitable for applications that require significant strength.

2. Yield Strength: The yield strength of GTS-55 steel grade is typically around 850 MPa, indicating its ability to withstand deformation under stress.

3. Elongation: GTS-55 steel grade typically exhibits a moderate elongation of around 12%-15%, which signifies its capacity to undergo deformation without breaking.

4. Hardness: The hardness of GTS-55 steel grade is usually within the range of 250-300 HB (Brinell hardness), indicating its resistance to indentation and wear.

5. Impact Strength: GTS-55 steel grade demonstrates good impact strength, allowing it to withstand sudden or repetitive loads without failure.

In summary, GTS-55 steel grade is a high-strength steel with notable mechanical properties. Its composition, which includes carbon, manganese, silicon, chromium, nickel, and molybdenum, contributes to its desirable features, such as high tensile strength, yield strength, hardness, and impact strength. These properties make GTS-55 steel grade suitable for various applications in industries such as manufacturing, construction, and automotive.
