S31803 is the Unified Numbering System (UNS) designation for the original duplex stainless steel. The UNS system was created by multiple trade groups in the 1970s to reduce confusion when the same alloy was called different things, and vice versa. Each metal is represented by a letter followed by five numbers, where the letter represents the metal series, i.e. S for stainless steel.

For paper mill applications requiring lower alloy grades that do not have sufficient corrosion resistance. Based on a 22% chromium content, they have a combined austenitic:ferritic microstructure that provides greater strength, corrosion resistance and cost-effectiveness.

The UNS S31803 (ASTM F51) specification has been largely superseded by UNS S32205 (1.4462, ASTM F60). This reflects their desire to maximize the alloy’s corrosion properties, thanks to the development of the AOD steelmaking process, which allows for tighter control of composition. In addition, it allows to influence the nitrogen addition level rather than just being present as a background element. Therefore, the highest performing duplex grades seek to maximize the content of chromium (Cr), molybdenum (Mo) and nitrogen (N).

Other elements can be added to the smelting compound of iron ore to produce different kinds of steel. Each type of steel can be used for specific industry applications ranging from construction to structural reinforcement.

310S stainless steel has good high temperature resistance. When the temperature exceeds 800 [1], it begins to soften, and the allowable stress begins to decrease continuously. The maximum operating temperature is 1200 ¡ãC. Due to the high content of nickel (Ni) and chromium (Cr), it has good oxidation resistance, corrosion resistance, acid and alkali resistance, and high temperature resistance. After the content, the strength is improved due to its solid solution strengthening effect. The chemical composition characteristics of austenitic stainless steel are based on chromium and nickel with elements such as molybdenum, tungsten, niobium and titanium added. Therefore, it has high strength and creep strength at high temperature.

The chemical balance allows the alloy to exhibit excellent resistance to carburization, oxidation and nitriding atmospheres. 800HT will not become embrittled even after long periods of usage in the 1200-1600 deg F range where many stainless steels become brittle. Excellent cold forming characteristics typically associated with the nickel-chromium alloys are exhibited with 800HT. When cold formed extensively the grain size produces a visibly undulated surface called “orange peel”. 800HT can be welded by the common techniques used on stainless steels.

ASTM A182 SS 310S Socket weld Flanges are very easy to be welded and fabricated, a quality it inherits due to its low Carbon.

Monel 400 and K500 nuts also exhibit excellent corrosion resistance in marine applications and have reasonable corrosion resistance to sulfuric and hydrochloric acids under reducing conditions. A standout feature of monel nuts is their excellent resistance to hydrofluoric acid, a particularly difficult acid to handle, at all concentrations up to the boiling point. For hydrofluoric acid applications, Monel nuts are probably the most corrosion resistant of all commonly used specialty alloys.

ASTM B462 UNS N08020 Slip On Flange Alloy 20 flanges provide good performance in hot sulfuric acid, specifically they offer good resistance to stress-corrosion cracking in boiling sulfuric acid at specific range of 20% to 40% concentration, as well as general sulfuric acid resistance.
