SUMMARY

The compressive strength of steel is generally equivalent to its tensile strength, meaning that steel reacts similarly to both stretching and crushing forces. For example, a steel with a tensile strength of 40,000 pounds per square inch (PSI) also exhibits a comparable compressive strength. However, specific grades like 4140 steel show a slight variation, with a compressive yield approximately 10% higher than its tensile yield. This information is crucial for understanding material properties in engineering applications.

PREREQUISITES
  • Understanding of tensile strength and compressive strength concepts
  • Familiarity with material properties of steel
  • Knowledge of steel grades, specifically 4140 steel
  • Basic principles of mechanics and material science
NEXT STEPS
  • Research the mechanical properties of different steel grades
  • Learn about the differences between tensile and compressive strength in materials
  • Investigate the applications of 4140 steel in engineering
  • Explore methods for testing compressive strength in materials
USEFUL FOR

Engineers, material scientists, and students studying mechanical properties of materials will benefit from this discussion, particularly those focused on steel applications in construction and manufacturing.

Many thanks to those who gave me input on my other question.

My new question is... what is the compressive strength of steel?

is it the same as the tensile strength? or critical compressive stress?

none of my textbooks list this value, and the really the only value i can find online on compressive strength is for concrete...

hit me with your best shot

In general, the tensile strength of steel is equivalent to its compressive strength. That is, steel responds to stretching force in much the same way it responds to crushing force

The tensile strength of a steel that can withstand 40,000 pounds of force per square inch may be expressed as 40,000 PSI or 40 KSI
 
For the most part, they are pretty close if not the same. Off the top of my head, one that comes to mind that is not the same but pretty close is 4140. It's compressive yield is slightly higher (about 10%) than it's tensile yield.
