Re: [MW:33411] MPI for duplex stainless steel

DSS is not good magnetize because it's structure Consists of two dual phase;  paramagnetic phase  called austinite 50% and magnetize phase called ferrite 50% , so you will find moderate magnetization not be well in inspection, it's better if you use PT method instead of MPI.

Magnite not catch properly on the DSS materials , so result is wrong, as per MPI procedures not allowing also

hi gents,

can we do Magnetic particle test for duplex stainless steel

i believe we can do since DSS is ferromagnetic material

whats expert opinion?

Re: [MW:35289] Welding consumable for S355J2WP material

S355 J2 WP  is a weathering structural steel  It has better atmospheric corrosion resistance. Use E 8018 - W1/W2  Electrodes This is regular...
