Piyush Steel is a leading manufacturer, supplier of high-quality Duplex Steel S31803 Pipe Fitting in the market. We follow the international standard and our product is inspected by a third party or inspection agency. We offer different shapes and sizes of pipe fitting and different diameters too. Duplex stainless steel alloy is having high corrosion resistance, good workability, and hardenable. It is a mixture of austenite and ferrite alloy that’s why it is showing ferrite and austenite both stainless steel properties. The toughness of duplex stainless steel is high compare to pure ferrite steel and sometimes its strength also higher compared to pure austenite.
S31803 has a property of resistance to stress chloride corrosion cracking duplex stainless steel shows the best corrosion property at a high temperature and in sulfide environment. The high amount of chloride is protected against corrosion and also work up to 300 degrees C. Duplex SS has a better ductility property at a low temperature compared to ferrite grade.

Different type of pipe fitting and its function
Couplings: - couplings are widely used in the industries for joining the pipes with different diameters. Coupling is used to stop leakage and it is of two types. One is regular and another one is slips coupling. Slip coupling is used to join two pipes and stop leakage between them. The regular coupling is used with rubber seal to join both pipes.

Adapters: - if a pipe has no proper end and length so the adapter used to increase of pipes’ length. As per the need, it connect the male and female threaded.

Reducer: - reducer is used where to less flow of liquid and it can change high flow size to low. It is connected to a pipe end and used to transferring liquid. The one end of the reducer is the same diameter as a pipe but the other one is a form of a cone which reduces the size of the pipe’s diameter.

The duplex steel pipe fitting used in various industries like chemical industry, liquid transformation, food and beverage industry, heat treatment, heat exchanger, petrochemical industry, oil and gas processing, offshore and ship building, boiler equipment, and power generation plant.

We use different testing like hardness test, macro, and micro test, toughness test, and mechanical test, chemical test, and flaring test etc. We provide the best packaging facility like wooden box, carton, etc as per our client requirement.

What are s31803 duplex stainless steel properties?

S31803 Duplex Stainless Steel is a ferritic-austenitic stainless steel with 22% Chromium (Cr), 5% Nickel (Ni), and 3% Molybdenum (Mo). It has high strength, high corrosion resistance in chloride environments, and excellent weldability. The mechanical properties of S31803 Duplex Stainless Steel include a maximum yield strength of up to 80ksi, an ultimate tensile strength of up to 110 ksi, and an elongation of over 40%. It also has good formability at both ambient and elevated temperatures. Additionally, its impact toughness is increased at lower temperatures.

What is Duplex UNS S31803 equivalent?

Duplex UNS S31803 is equivalent to ASTM A182 F51, which is a super duplex stainless steel grade. It also has equivalents in other materials such as AISI 318LN, AFNOR Z3 CN 18-02, and JIS SUS329J3L. Additionally, this grade of duplex stainless steel is identified by multiple standard designations and material numbers including UNS S31803, UNS F51, SS2377, BS318S13, 1.4462 and EN 10088-3 X2CrNiMoN22-5-3.
