Which steel has this composition?

In summary, the chemical composition of the steel is 98.4% iron, with varying amounts of other elements such as carbon, manganese, silicon, and chromium present in smaller percentages. The steel is classified as a medium carbon steel with good wear resistance due to the presence of manganese.

carbon steel?

Changing the title makes me look foolish. The original title was "what material is this". After that, you expect me to help you? Forget it!

Hello encik_lai,

The only element of interest there is C with it's 0.47% suggesting a mild carbon steel unalloyed. Like http://www.matbase.com/material-cat...erial-properties-of-high-grade-steel-c45.html
So close to a C45 or 1.0503.
The other impurities are the usual result of melting down 2 oil-tankers 500 cars and nuclear reactor parts and low purification thereafter as this steel is not with very expensive properties.

Ah forgot to mention, all said above is true for mass %.

Fe 98.4, Mn 0.67, C 0.472, Si 0.216, is a medium carbon steel, not a mild steel.The Mn gives it some wear resistance.

Medium carbon steel: approximately 0.29% to 0.54% carbon content with 0.60 to 1.65% manganese content (e.g. AISI 1040 steel). Balances ductility and strength and has good wear resistance;

Related to Which steel has this composition?

1. What is the composition of the steel?

The composition of steel refers to the percentage of elements present in the alloy. This can include carbon, chromium, nickel, and other elements that impact the properties of the steel.

2. How does the composition affect the properties of the steel?

The composition of a steel alloy greatly influences its strength, hardness, ductility, and other mechanical properties. For example, a higher carbon content results in a stronger and harder steel, while a higher percentage of nickel can increase its corrosion resistance.

3. How do I determine the composition of a specific steel?

The composition of a steel can be determined through various methods, such as chemical analysis, spectroscopy, and X-ray diffraction. These techniques involve analyzing the alloy's elemental composition and identifying the presence of specific elements.

4. Are there standards for steel composition?

Yes, there are various international and national standards that specify the acceptable ranges of elements in different types of steel. These standards help ensure the quality and consistency of steel products for various applications.

5. Can the composition of steel be modified?

Yes, the composition of steel can be modified by adding or removing specific elements during the manufacturing process. This allows for the production of different types of steel with varying properties to meet specific requirements.
