The microstructures inside duplex stainless steels are approximately 50 percent austenite and 50 percent ferrite, and consequently, duplex products share the physical properties of both ferritic and austenitic grades. Duplex stainless steels are resistant to the cracking caused by chloride stress corrosion in austenitic grades and have improved resistance to localized corrosion. This family of stainless steels has roughly twice the yield strength of their counterpart austenitic grades which means we can use it to design thinner gauge tubing. Higher hardness values provide better wear resistance for high precision tubes.
Duplex steels are easily welded and formed, similar to austenitic grades. Depending on chromium, nickel and molybdenum content, duplex stainless steels are divided into four main categories: lean duplex, duplex, super duplex and hyper duplex. This family of alloys has great advantages in both material and engineered fabrication costs.
Typical applications for this alloy group include heat exchanger tubes, umbilicals, structural tanks, pulp and paper making equipment, pipes and fittings, and seawater handling systems.

ALLOY STEEL TUBES & ALLOY STEEL PIPES
Alloy Steel contains substantial quantities of elements other than carbon such as nickel, chromium, silicon, manganese, tungsten, molybdenum, vanadium and limited amounts of other commonly accepted elements such as manganese, sulfur, silicon, and phosphorous.
Addition of such alloying elements is usually for the purpose to increase hardness, strength or chemical resistance.
Pipes made of alloy steel have exceptional performance properties.
These are generally developed for energy-related applications involving oil and gas drilling and are subjected to stresses in machine parts.

STAINLESS STEEL PIPES & TUBES
Application in high demanding industries and sectors, particularly high temperature and corrosive services.
Stainless steel seamless pipes and stainless steel seamless tubes are reliable long lasting and on par with international quality and safety norms
Stainless Steel ERW, EFW and Stainless Steel Seamless Pipes and Stainless Steel Seamless tubes.
Applications include attractive appearance, corrosion resistance, low maintenance and strength of stainless steel.
Stainless steel is more expensive than standard grades of steel but it has greater resistance to corrosion, needs low maintenance and has no need for painting or other protective coatings.
These factors mean stainless steel can be more economically viable once service life and life-cycle costs are considered.
