DUPLEX STAINLESS STEEL BARS : PRODUCT

Duplex stainless steel is a resolute and tough steel that can manage temperatures up to minus 80 degrees C. The strength of the duplex stainless steel bars makes it possible to weld on the thicker sections of the bars if needed. However, this should be done with uttermost care. Duplex stainless steels offer high strength which in turn leads to weight saving. Compared to most bars available in the industry, duplex stainless steel bars have one of the best price stability. Duplex stainless steels also promote excellent resistance to corrosion as well has have very high mechanical strength. The corrosion resistance properties are said to be inherited from its ferritic side. Duplex stainless steels came to be known as “duplex” because of their two-phase microstructure which consists of grains of both, ferritic and austenitic stainless steel.
