The word Duplex means double layer material, So Duplex Stainless steel is that whose microstructure consist of two phases having grains of austenitic (face -centered cubic lattice) and delta ferrite (body centered cubic lattice) in equal proportion i.e 50-50 %.
The duplex steel began to be looking as best alternative in market to fulfil or overcome the deficit of austenitic and ferritic steels due to its higher strength, good weldability and high resistance to crevice, stress & pitting corrosion cracking as it is a mixture of both.
Due to presence of molybdenum in this grade, it exhibit very good thermal heat conductivity, toughness, higher temperature strength and high resistance to radiation swelling which makes it more demanding and good future aspect for the steel industries worldwide for many applications.
The duplex Stainless steel exhibit various appealing properties which gives value to its family as shown below:
Cost saving benefits with attractive properties makes the Duplex Stainless Steel a good choice for Steel Industries Project.
Due to lower nickel content, the cost of these grades are comparatively lower than austenitic grades especially when the alloy surcharge is on higher side. It also possess good thermal conductivity as compared to austenitic grades due to presence of lower nickel content.
Price are much more stable in duplex grades as compared to austenitic grades if we see over the long period of time due to low alloying elements.
Application of Duplex Stainless Steel
The duplex stainless steel has a demand in those applications where high strength and corrosion resistance is required as shown below.
Ambica steels offers Duplex Stainless Steel Round Bars – Balance is the Key…..
The structure and metallurgy of Duplex Stainless Steel is very much complex as compared to Austenitics and Ferritic grades which is very difficult to produce. The balance of maintaining the properties is most important key factor in producing duplex steel.
We are specialize and having a rich experience to produce this grades in our regular practice which makes us different and superior from others suppliers in India.
We are supplying many grades of this family globally on regular basis such as
