Quiz on Ferritic Test Welcome to your Quiz on Ferritic Test 1. What is Ferrite testing: It is a technique used to measure the delta ferrite content in austenitic stainless steel duplex stainless steel Both of the above 2. Ferrite testing is considered a form of nondestructive testing. True False 3. Measuring the delta ferrite content helps in establishing Mechanical properties Weldability Corrosion resistance All of the above 4. If the ferrite content is too low, then the stainless steel may be susceptible to solidification cracking (hot cracking) upon welding True False 5. If the ferrite content is too high, then the risk of corrosion decreases. True False 6. Mechanical properties of the stainless steel could be negatively affected if the ferrite content is too high True False 7. The presence of ferrite in the range of 4-8% in austenitic stainless steel welds is ideal True False 8. In duplex stainless steels, 35 to 65% ferrite is preferred, though 50% is optimum True False 1 out of 4
