Global steel is one of the largest exporters, manufacturers, and suppliers of Duplex S31803 Instrumentation Fitting which is available in different types, sizes, specifications, dimensions, thicknesses, and so on and it is also customized as per the exact need of our buyers.

We are a leading supplier of Duplex S31803 Instrumentation Fitting. We use the best raw material to manufacture our products. These materials are tested by our professional experts.

Duplex S31803 Instrumentation Fitting has higher mechanical strength and ductility. These fitting can be operated in the pitting and crevice corrosion environments. We serve our customers with genuine products made from the finest of raw materials. Duplex S31803 instrumentation fitting has a microstructure having a 50/50 austenitic and ferritic.

Duplex S31803 is low in cost due to the lower nickel and molybdenum content present in it. Duplex S31803 Instrumentation Fittings have excellent corrosion resistance to saltwater and most sulfuric acid concentrations.

Furthermore, it is resistant to sulfide stress corrosion cracking (sour-gas environments).
There are several benefits of using Duplex S31803 Instrumentation Fitting which include high resistance to stress corrosion cracking, fatigue, and erosion, excellent resistance to chloride stress corrosion, good workability and weld ability, and many more. This grade has a ferritic and austenitic structure that is ideal for industrial application. It has good oxidation resistance at even the highest of temperatures.

Duplex instrumentation fittings are widely used in chemical processing and petrochemical plants, paper, and pulp digesters, the food industry, hot liquid tanks, and presses, oil and gas exploration plants, and processing equipment of several industries, in equipment related to pollution control and many more. It has a higher work hardening rate than standard grades.
