Super duplex stainless such as duplex is a mixed microstructure of austenite and ferrite which has improved strength over ferritic and austenitic steel grades . The main difference is super duplex has a higher molybdenum and chromium content which gives the material greater corrosion resistance .
Super duplex has the same benefits as its counterpart - it has lower production costs when compared with similar ferritic and austenitic grades and due to the materials increased tensile and yield strength , in many cases this gives the purchaser the welcomed option of purchasing smaller thicknesses without the need to compromise on quality and performance .
Application:
a) Petroleum
b) Chemical industry
c) Instrument
d) Industrial transportation
e) Mechanical structure industry
f) Need high corrision ability pipe's industry, such as offshore industry etc
Advantages:
a) Superior surface finish,
b) Better mechanical property
c) More precise dimension
d) Perfect inspection method and inspection equipment
