S32750 Super Duplex Pipe

Aesteiron Steels Pvt Ltd, is S32750 Super Duplex Supplier in India. We have exported high quality S32750 pipe, S32750 tube, S32750 plates & S32750 sheets to many countries with best quality & finish.

What is Duplex Stainless Steel?
Duplex stainless steel is called duplex because it has two phase micro structure consisting of grains ferritic  & austenitic stainless steel. When duplex stainless steel is melted it solidifies from the liquid phase to completely ferritic structure. As the material cools to room temperature about half of the ferritic grains transforms to austenitic grains. The result is a microstructure of roughly 50% austenitic & 50% ferritic.

Duplex 32750 Description
Super duplex stainless steel s32750 is supplied in the solution annealed condition. It is combination of both austenitic & feritic grades. The higher chromium, molybdenum and nitrogen contents result in a Pitting Resistance Equivalent number (PREN) of >41, providing pitting and crevice corrosion resistance superior to austenitic and duplex stainless steels in almost all corrosive media, and a Critical Pitting Temperature exceeding 50°C.
