What is the compressive strength for mild steel?
The compressive strength of mild steel is 4.75 – 25.2 tonnes / sq. cm. It's ultimate tensile strength is 5.51 – 11.02 tonnes / sq. cm.
The compressive strength was calculated by using the equation  : F= P/A, where F is compressive strength of specimen in Mega Pascal, P is the maximum applied load by newton and A is the cross-sectional area estimated in mm 2 . ...
The ultimate compressive strength of mild steel varies from 800 to 1200 n/mm2.
In other words, compressive strength resists compression (being pushed together), whereas tensile strength resists tension (being pulled apart). In the study of strength of materials, tensile strength, compressive strength, and shear strength can be analyzed independently.
Most structural steel has a compressive strength of approximately 25,000 psi. By comparison, the compressive strength for concrete is typically around 4,000 psi. (However, it can be higher if it is reinforced with steel.)

The compressive strength of steel is about 250 MPa while that of concrete ranges from 30MPa to 80 MPa. So the compressive strength of steel is about 5 times more than that of concrete.
Steel is very strong in both tension and compression and therefore has high compressive and tensile strengths. Steel has an ultimate strength of about 400 to 500 MPa (58 – 72.5 ksi). It is also a ductile material that yields or deflects before failure.
As its name implies, compressive strength is the maximum amount of pressure or compression a metal can withstand. This is typically measured with a universal testing machine that applies an increased load on the material.
All factors considered, steel is stronger and just generally a better option than concrete in most scenarios. Topping the list of reasons is steel's ability to withstand higher tensile loads and compressive loads than reinforced concrete.
Does steel have a higher compressive strength than concrete?
However, steel trumps concrete because of the strength-to-weight ratio. As mentioned before, it has the highest ratio of all construction materials and is therefore significantly stronger than concrete. Adding to its strength is steel's ductility and flexibility.
Concrete compressive strength requirements can vary from 2,500 psi for residential concrete to 4,000 psi and higher in commercial structures. Higher strengths up to and exceeding 10,000 psi are specified for certain applications.
Steel is more or less a linear elastic material. Unlike concrete, which is much weaker in tension than in compression, steel theoretically responds the same way in either tension or compression. However, with enough applied force, steel and other metals will cease to behave elastically and begin to behave plastically.
The ratio of tensile to compressive strength is lower for higher compressive strengths. One of the most common relations is given by the following relation: Tensile strength = K (compressive strength)n. The value of K may be taken as 6.2 for gravel and 10.4 for crushed aggregate.
For a linear isotropic Hookean material, the Young's modulus of elasticity is the same for compression and tension. where E is the Young's modulus, σ is the normal stress and ϵ is the normal strain.
Based on Matweb data, the compressive yield strength of a36 is 22000 PSI.
So, among the given options high carbon steel has the highest compressive strength as compared to other options. The carbon content is 0.5%−1.5% and such steel is called high steel.
(viii) Its ultimate compressive strength is about 80 to 120 kN/cm2.
The permissible compressive stress in concrete due to bending is 7 N/mm2 .
Mild steel is made up of an iron (Fe) base with the addition of small amounts of carbon. Low-carbon steel is typically defined as having less than 0.2 % carbon by ASM International. Different grades of mild steel are defined by their differing levels of carbon. Another common alloying element is manganese (Mn).
