What is tensile strength of marine quality mild steel plate?

according to ASTM A36 Marine grade mild steel plate has a tensile strength of 58 - 80 thousand psi.


What happen if tensile strength of A36 Material exceed the ultimate tensile strength allowed by ASTM specification?

The raw steel specification A36, has a maximum tensile strength of 80 ksi. This is the same maximum strength as ASTM standards like A307 grade C or F1554 grade 36. I'm not familiar with any other specifications that would use A36 and have a higher maximum strength. The A36 steel would be out of tolerance if it exceeds a 80 ksi tensile. Being out of tolerance in this way could indicate other properties are also out of tolerance in a less favorable way. The steel would be less ductile, for instance, and impact properties might be reduced.

What is difference between limit of proportionality and tensile strength?

The proportional limit is the stress value at which the stress is no longer linear with strain. After that, the material will begin to yield and become non-linear, or plastic, and then it will fail at a higher value called the tensile strength. For most metals, the proportional limit is well below the tensile strength; for example annealed stainless steel has a proportional limit near 30 ksi and tensile strength of 80 ksi; aluminum has a proportional limit of 35 ksi and tensile strength of 42 ksi.

Can a 4 inch steel pipe handle a 50000 pound axial load?

Steel has a crush strength of 95,000 psi and a tensile strength of 55,000 psi. A Sch. 80 - 4" steel pipe has a cross-sectional area (of steel) of 4.407 sq. in. This can handle a load in tension of ~242,000 pounds before failure. And a load in compression of ~ 418,000 pounds before failure. 50,000 pounds is well within the factor of safety for both loads in tension or in compression, provided there are no shear forces applied.
