In the E71T-X designation, the "71" indicates tensile strength of approximately how many ksi?

In the E71T-X designation, the "71" indicates tensile strength of approximately how many ksi?

• A. 70 KSI
• B. 75 KSI
• C. 65 KSI
• D. 90 KSI

Answer: (A)

Understanding this designation: the digits after the E show the nominal tensile strength in ksi. In an E71T-X electrode, the “71” corresponds to about 71 ksi of tensile strength. When you’re asked for an approximate value, you round to the nearest whole ksi, which is about 70 ksi. The remaining letters specify the electrode type and variant (T indicates tubular flux-cored wire, X being a specific product variation), but they don’t change the strength value. So the closest, correct approximation is 70 ksi.
