A479 is a specification for bars and rods produced in several grades of austenitic, ferritic, duplex or simply austenitic-ferritic and martensitic stainless steels. Since this designated stainless steel A479 round bar can be produced in any of the above grades, it can be heat treated differently.

AL-6XN alloy (UNS N08367) is a low carbon, high purity, nitrogen-bearing ¡°super-austenitic¡± stainless alloy. The AL-6XN alloy was designed to be a seawater resistant material and has since been demonstrated to be resistant to a broad range of very corrosive environments.

Stattin Stainless stocks a complete range of grades 304 and 316 fittings. The range includes 45¡ã, 90¡ã and 180¡ã LR Elbow, 90¡ã SR Elbow, Equal Tee, Unequal Tee, Concentric Reducer, Eccentric Reducer, Cross, Hose Tail, Seal Flange, cover and spray ball.

In addition to nickel, the alloy also contains a large amount of copper. Not only does copper make the UNS S08904 screw resistant to seawater and salt water, it also improves the alloy’s sulphur resistance. The addition of copper content to stainless steel 904L hex bolts provides higher corrosion resistance than conservative chromium-nickel alloys, especially phosphoric, acetic and sulfuric acids.

SMO 254 FLANGES are the perfect option for engineering assemblies; it can be used in high strength assemblies, constructional works as well as fitting machine components. This opposes wear and tears in the exertion of high torques, resists crushing in high machine fittings.

SAE 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. It is less electrically and thermally conductive than carbon steel. It is magnetic, but less magnetic than steel. It has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes.[1]

Our high quality stub end A-type stub end butt welded joints are tested and proven for durability, accuracy and precision. ANSI B 16.9 Stub End is widely used in plumbing engineering to connect different types of pipes.

The flange is second most used joining method after selding. Flanges are used when joints need dismantling. It provides flexibility for maintenance. Flange connects the pipe with various equipment and valves. Breakup flanges are added in the pipeline system if regular maintenance in required during plant operation.
A flanged joint is composed of three separate and independent although interrdlated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls are required in the selection and application of all there elements to attain a joint, which has acceptable leak tightness.
A flange is a protruded ridge, lip or rim, either external or internal, that serves to increase strength (as the flange of an iron beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a rail car or tram wheel, which keep the wheels from running off the rails). The term “flange” is also used for a kind of tool used to form flanges.

Greater strength and corrosion resistance still mandate the use of seamless stainless steel and nickel alloy tubing for high pressure applications within the oil and gas, petrochemical, chemical, energy, and pulp and paper industries.

Highly resistant to corrosion and aesthetically pleasing, stainless steel is used in a wide variety of industries for various applications.

Stainless steel flange simplified as SS flange, it refers to the flanges that made of stainless steel. Common material standards and Grades are ASTM A182 Grade F304/L and F316/L, with pressure ratings from Class 150, 300, 600 etc and to 2500.

The anti-corrosion properties that make 316 steel unique come from the molybdenum in its composition. These properties make 316 the first choice for some specific applications where extreme corrosion resistance is required. Such applications include heavy duty marine projects and industrial applications where steel is often in contact with harsh corrosive substances.

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 A182 F316 Long Weld Neck Flanges
Featuring 304 stainless steel for very good corrosion resistance, this GRAINGER APPROVED weld neck flange can be attached to a system via a circumferential weld at the neck. The welded area can be easily examined by radiography. Matched pipe and flange bore reduces turbulence and erosion inside the pipeline.

Stainless Steel 316L fasteners are made of low carbon austenitic stainless steel. The material is carbon, manganese, silicon, phosphorus, sulfur, 18% chromium, 2% molybdenum, 10% nickel and nitrogen. There are different types of fasteners such as SS UNS S31600 square bolts, hex bolts, screws, nuts and washers.

Zinc-plated hex nuts are made of grade 2 carbon steel for joining metal and wood parts. They are also used with bolts, screws, studs, threaded rods and any other fasteners with machine threads.

It is extensively used in heavy gauge welded components (over about 6mm). There is commonly no appreciable price difference between 316 and 316L stainless steel.

?The low carbon content of Alloy 317L enables it to be welded without intergranular corrosion resulting from chromium carbide precipitation enabling it to be used in the as-welded condition.

The molybdenum gives SS 316 better overall corrosion resistant properties than Stainless Steel 304, particularly higher resistance to pitting and crevice corrosion in chloride environments.

Butt weld flanges are typically used in applications where high pressure is a concern. The inner diameter of the flange is designed to match the inner diameter of the pipe. Butt weld pipe flanges with hubs are available in published sizes from 1/2″ to 96″. Our company manufactures butt weld flanges in all material grades, sizes and sizes.

The stainless steel water supply pipe flange has all the properties of stainless steel materials, one of which is the strong corrosion resistance, which can permanently maintain the integrity of the design.
