Steel Flashcards
What is the main ingredient in structural steel?
iron ore
What are the 2 main ingredients in STAINLESS STEEL
iron ore
Chromium
What year was modern structural steel invented?
1856
What does the acronym CSA stand for?
Canadian Standards Association
What doe the acronym ASTM stand for?
American Society for Testing Materials
What does the acronym SAE stand for?
Society of Automotive Engineers
Other than iron ore, what is the other main ingredient in stainless steel?
chromium
What does ductile mean?
material will deform under pressure and absorb a lot of energy before failure
What does bending moment mean?
the reaction included in a structural element when an external force or moment is applied to the element, causing the element to bend.
What does tension mean?
Describe what strength is:
the amount of loading a member can carry without permanent deformation occurring.
Identify 6 types of beams and describe them:
T-Bar
L-Angle (upside down L)
HSS (hollow square)
Wide Flange (like an I beam)
I-Beam (thinner joints)
Channel (like a letter C)
What does Young Modulus graph demonstrate?
The stress and strain curve to show strength of material (when it will bend, break, etc)
MEASURES TENSILE AND COMPRESSIVE STIFFNESS
Why does process of cold rolling steel increase it’s strength?
formed before crystallization, makes steel more durable because it’s compressed into thin layers.
Why are stiffeners added to the sides of I-beams?
to increase strength of joint
