Titanium Round BarDuplex UNS S31803 is a duplex grade with ferritic-austenitic structures. This alloy contains 40-50% ferrite in the annealed condition. This grade is filled with prominent attributes so that these are preferred for engineering application. Generally, Duplex UNS S31803 grade is used for manufacturing bars, sheets, and wires. The duplex alloy is fully austenitic in nature also available in magnetic and nonmagnetic state. The duplex structure has highs strength ferritic grades retaining the excellent corrosion resistance.

Duplex steel is tempered and quenched with water moderately. Thus, the endurance limit towards cracking is improved. Moreover, the grade comes with machining allowance and tolerance limit so as to use different applications. Duplex UNS S31803 grade product is processed by using top notch crude materials. The selection of good composition resting elements retains resistance towards harsh chemicals, sulfides, chlorides, and acids.

Duplex UNS S31803 Bars are forged out from the hot or cold working process and treated with the heat treatment process. Whereas, the sheet is rolled out with industrial rollers and finished. Additionally, these are coated with SATIN or bright polish to avoid oxidation damages. The wires manufactured from using a drawing process to get the desired product.

Maintenance of Duplex UNS S31803 Bars, sheets & wires:

The duplex alloy is processed from unwanted phases especially in the heat treatment process. If it does not go under control process it will lead to embrittlement, loss of toughness, and also reduce in corrosion resistance. The phase likely to occur when cooling rate while processing is not fast enough. The high annealing process greater the probability of sigma phase. Thus, the duplex alloy is more prone to this problem. At 475 C another form of embrittlement occurs and also forms as low 300C, this limits the design procedure of duplex alloy grade.

Tests performed on Duplex UNS S31803 Bars, sheets & wires:

In order to supply superior products to clients, manufacturers perform different tests on products. All the tests performed here are done with under the set industrial norms and guidelines of professions the tests are hardness test, tensile test, Mechanical test, positive material test, micro and macro test, chemical test/ spectro analysis, and intergranular corrosion test. Further tests are flaring test, flattening test, ultrasonic test, radiographic test, pitting corrosion test, and visual inspection.

Summary:

The duplex alloy has double strength. These poses good corrosion resistance depending on the application requirement also have good toughness below to -50C. Welding in the thin and thick section is possible.  No additional effort is required due to its good mechanical properties. Serve the best service up to 300C temperature.
