It's a unit. 1 KSI = 1000 PSI. It is just used to 'neaten' the numbers: 70 KSI rather than 70,000 PSI for example.
60 ksi
high tensile stainless steel
1 ksi is equal to 1,000 psi
Its a stronger type of steel and 60 ksi steel was used to build Taipei 101.

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.

Tensile strength is given in ksi. To get pounds you need to know the area. Pounds = strength x area. For example if the specimen is 100 ksi strength and area 1 sq inch, pounds = 100 x 1 = 100 kilopounds = 100000 pounds. f the specimen is 100 ksi strength and area 2 sq inch, pounds = 100 x 2 = 200 kilopounds = 200000 pounds. In any case strength in ksi is the same for a given material and that is why ksi is used.
KSI steel bar refers to a type of steel reinforcement bar (rebar) that is designated by its yield strength in kilopounds per square inch (KSI). Common grades include 40 KSI, 60 KSI, and 75 KSI, indicating the minimum yield strength. These bars are used in construction and civil engineering to reinforce concrete structures, providing tensile strength and improving durability. The higher the KSI rating, the stronger the bar, allowing for lighter designs and reduced material usage.
The compressive strength of Phosphor Bronze is directly proportional to the tensile strength, For example 1/2 hard phosphor bronze has a Tensile Strength of 60 to 75 ksi and a Yield Strength of 45 to 70. For typical engineering calculations, the compressive strength can be considered equal to the yield strength.
Tensile Strength is 570 MPa (i.e. 82.7 ksi) - (Ref. API 5L - Specification for line pipe - Forty Forth Edition Section 9.3.2- Table 6)
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.
KSI, or kilopounds per square inch, is a unit of measurement used to express the strength of materials, particularly in the context of tensile strength and yield strength. It is not directly related to the quality of tubing, which encompasses factors like material composition, manufacturing processes, and surface finish. However, higher KSI values generally indicate stronger materials, which can contribute to the overall quality and performance of tubing under stress.
ASTM 1011 comes in many grades which determine the yield strength ie:1011 gr 42 would have a min yield of 42,000 psi
In the designation E-308-16 for an electrode, the number 16 refers to the tensile strength of the weld metal produced by the electrode, measured in ksi (thousands of pounds per square inch). Specifically, it indicates a minimum tensile strength of 70 ksi (about 483 MPa). The "308" part indicates the chemical composition of the electrode, which is suitable for welding austenitic stainless steels, primarily those with a composition similar to 18% chromium and 8% nickel.
The 36 stands for the yield strength in ksi Fty = 36 ksi = 36,000 psi
