Duplex stainless steel tube has good welding performance, compared with ferritic stainless steel and austenitic stainless steel, it is not like the welding heat affected zone of ferritic stainless steel, because of the severe coarsing grain and the plastic toughness is greatly reduced, nor like austenitic stainless steel, is more sensitive to welding hot crack.Because of its special advantages, duplex stainless steel is widely used in petrochemical equipment, seawater and wastewater treatment equipment, oil and gas pipelines, papermaking machinery and other industrial fields.

2507 (UNS S32750) duplex stainless steel has strong strength and corrosion resistance, which is mainly used in chemical processing, petrochemical industry and subsea equipment. It has strong chloride corrosion resistance, high thermal conductivity and low coefficient of thermal expansion. The high content of chromium, molybdenum and nitrogen makes it highly resistant to patchy, crevice and general corrosion.

Super Duplex Steel UNS S32760 Welded Pipes are multi-purpose and possess good weldability, used widely in the offshore and marine industry for their acid corrosion resistance.S32760 Super Duplex Stainless Steel Pipes are highly alloyed with different metals and have a greater mechanical strength.

Type 301 is an austenitic chromium-nickel stainless steel that is available in the annealed and cold worked conditions. In the annealed condition, Type 301 offers the highest level of stretch formability of any stainless steel and in the heavily cold worked condition offers the highest strength level of any 300 series stainless steel. Type 301 is non-magnetic in the annealed condition but becomes magnetic as a result of cold working.Type 301 is corrosion resistant in many environments, but the corrosion properties are less than that of 304/304L stainless steel.

Well known for its high impact strength, UNS S32760 displays no ductile-brittle transition but only a slight reduction in impact energy as temperature decreases.

Stainless steel has been widely used because of its high corrosion resistance and decoration, especially in medical appliances, food industry utensils, tableware, kitchen utensils and other aspects have been popularized and promoted. Stainless steel appliances should be corrosion resistant, bright and clean appearance, appliance surface should not be attached with toxic substances to human body.

ASTM A790 refers to stainless steel seamless and welded pipes (UNS S31803, UNS S32205, UNS S32750, UNS S32760). These tubes can be easily cut and molded by bending, stretching, extrusion, and other common procedures. Consideration should be given to its high intensity and the resulting larger springbok.

Duplex Steel UNS S32205 Round Bars have a long service life and low maintenance cost and hence can be used in various industrial applications like oil and gas exploration and processing equipment, chemical and petrochemical processing equipment, high chloride and marine environments, power generation, specialty chemicals, gas processing, seawater equipment, pulp and paper digesters, etc.Product Parameter：Stainless Steel barMaterial200 series: 201,202,202Cu,204Cu,300 series: 301, 303/Cu, 304/L/H, 304Cu, 305, 309/S, 310/S, 316/L/H/Ti, 321/H, 347/H, 330,400 series: 409/L, 410, 416/F, 420/F, 430,

UNS S32760 is able to compete strongly with the 6% molybdenum “super austenitic” grades in some applications, as it has fewer amounts of Mo and Ni which drive up the base cost of the material. Although, 32760 has lower amounts when compared to “6% Moly” grades it still has higher contents of Cr, Ni, and Mo when referring to other alloys, these elements improve the intergranular and pitting corrosion resistance of the material.
