304 stainless steel is the most common stainless steel. The steel contains both chromium (between 18% and 20%) and nickel (between 8% and 10.5%)[1] metals as the main non-iron constituents. It is an austenitic stainless steel.When it comes to uses, SS304 can be found in kitchen sinks and other appliances such as toasters and microwave ovens. SS304 is also used to make pressure vessels, wheel covers as well as for building facades.

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The UNS S31803 (ASTM F51) specification has been largely superseded by UNS S32205 (1.4462, ASTM F60).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).

ASTM A403/ A182/ A240 and ANSI B16.9/16.28/ B16.25/ MSS SP-43. 316/316L is a nickel-chromium stainless steel alloy to which copper and molybdenum have been added. It is a non-magnetic austenitic stainless steel, so it is especially useful in severely corrosive conditions.

Two criteria for evaluating oxidation resistance are weight change and depth of corrosion penetration. HASTELLOY X pipe bend excels in both respects due to the formation of a protective, tenacious oxide film.

Cast stainless steel pipe fittings such as 304 and 316L can be used in all types of water, including drinking water in public supply. They have an excellent resistance to the full range of potable waters, including various chloride levels. At the end of its useful life, cast stainless steel is fully recyclable and retains a higher residual scrap value than ordinary cast steel.

Stainless grade 316Ti contains a small amount of titanium. The titanium content is usually only around 0.5%. Titanium atoms stabilize the structure of 316 at temperatures in excess of 800¡ãC.

Inconel 600 alloy is arguably a standard engineering material used in a variety of applications requiring high temperature and corrosion resistance. Inconel 600 fittings have some excellent mechanical properties and are popular for their enhanced strength and high workability. Due to its chemical composition, the material possesses all these excellent properties. It contains high concentrations of various important elements such as chromium, molybdenum and nickel. It also shows good antioxidant properties.

Inconel 600 butt welded fittings are also resistant to stress-related corrosion cracking in chloride environments. They are effective against alkaline environments. Inconel 601 fittings also exhibit all of these properties, but due to the addition of aluminum to their chemical composition, they exhibit improved mechanical performance even in extremely hot environments.

Stainless Steel 316H Butt Weld Fittings may be susceptible to chloride stress corrosion cracking, where post-weld heat treatment is generally not required. Stainless Steel 316H Butt Weld Pipe Fittings may also be used as an alternative to 316 for heavy section welding.

Elbow A234 WPB are devided into two categories which define the distance over which they change direction.

Incoloy 800 is an alloy whose primary constitution is made up of nickel, iron, and chromium. This particular alloy, unlike the former, has less than 50% nickel content in its chemical composition. Aside from their chemical makeup, the other points of distinction for both the alloys are their use in a specific set of applications or industries.

316 and 316L are austenitic alloys, which means that these stainless steel products achieve corrosion resistance through the use of iron carbide or a non-magnetic solid solution of carbon in iron during the manufacturing process. Compared to chromium-nickel austenitic stainless steels, 316L stainless steel has higher creep, rupture stress and tensile strength at elevated temperatures.
