There are different types of fasteners such as SS UNS S31600 square bolts, hex bolts, screws, nuts and washers.

Stainless steel grade 254 SMO Pipe is a very high end austenitic stainless steel.

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]

316 Stainless Steel’s resistance to corrosion and contamination, low maintenance, and a familiar luster make stainless steel an ideal material for many applications that require the strength and corrosion resistance of steel. In addition, stainless steel can be rolled into sheet, plate, bar, wire and tube. These can be used in cookware, tableware, surgical instruments, major appliances, vehicles, construction materials in large buildings, industrial equipment (eg, paper mills, chemical plants, water treatment), and storage tanks and tankers for chemicals and food.

Alloy 310S Seamless Pipes has oxidation resistance to 2000°F. ASME SA312 SS 310S Seamless Pipes has moderate strength at high temperature. UNS S31008 Seamless Pipes is quite resistance to hot corrosion. Also referred as WNR 1.4845 Seamless Pipes, it has strength and toughness at cryogenic temperatures. It is readily fabricated by standard commercial procedures. In comparison to carbon steel, these stainless steels are tougher and tend to work harden rapidly.

normalized basis
Normalizing removes impurities from steel and increases its strength and hardness. This is achieved by changing the size of the grains to make them more uniform throughout the steel sheet. The steel is first heated to a specific temperature and then cooled by air.

Most iron-based metals react with water to produce the reddish iron oxide known better as rust. The oxygen atoms in the water pulls iron off of the base metal to form the porous rust structure with no real strength.

The fusion welding properties of stainless steel 304 are excellent with or without fillers. The recommended filler rod and electrode for use with 304 stainless steel is grade 308 stainless steel. For 304L, the recommended packing is 308L. Heavy welded sections may require post weld annealing. The 304L does not require this step. If post weld heat treatment is not possible, grade 321 may be used.

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.

Stainless Steel 904L Flange contains high amounts of expensive ingredients, such as molybdenum and nickel. Today, most of the applications that employ grade 904L are replaced by low-cost duplex stainless steel 2205.

ASTM A403 WP316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments.

904L is having very good resistance ability against reducing acids and the addition of copper is giving it general corrosion resistance to various concentrations of the sulphuric acid.

Stainless steel fasteners are used for corrosion resistance. Contrary to popular belief, stainless steel fasteners are not strong, but they do provide excellent resistance to rust, stains and corrosion. Stainless steel nuts, bolts, screws and washers should be your first choice when looking for fasteners that will fight the elements of the outdoors, especially water. The finish of stainless steel depends on the amount of chromium in the material.

Incoloy 925 flange also contains additional levels of titanium and aluminum compared to 825.

316 and 316L steel plates and tubes have common properties and are often double certified, which confirms that both have properties and compositions consistent with both steel types. The Model 316H was excluded from this because, unlike the 316 and 316L, the 316H was designed to operate at higher operating temperatures.

A flange is a ring of steel (forged, cut from plate, or rolled) designed to connect sections of pipe, or to join pipe to a pressure vessel, valve, pump or other integral flanged assembly. Flanges are joined to each other by bolts, and to the piping system by welding or threading (or loose when stub ends are used). 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. It used in more industries than carbon steel as stainless steel has better resistant performances on corrosion environment and always provides with a good appearance.

Molybdenum and nitrogen content significantly increased the resistance of pitting and crevice corrosion in the halide media. Meantime, nickel and nitrogen not only ensures the stability of metallographical, but also reduce separating intergranular trend in the thermal process or welding process better than the nitrogen content of nickel alloy.

This grade has surpassed its original intent and overlapped into many industries proving useful owing to its high level of molybdenum amount other elements, which allows 31254 to be used successfully in various applications such as Flue gas desulfurization and Chemical environments.

Stainless steel types 1.4301 and 1.4307 are also known as grades 304 and 304L respectively. Type 304 is the most versatile and widely used stainless steel. It is still sometimes referred to by its old name 18/8 which is derived from the nominal composition of type 304 being 18% chromium and 8% nickel.

Stainless steel is an alloy of iron that is resistant to rusting. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel’s resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen.
A stainless steel pipe system is the product of choice for carrying corrosive or sanitary fluids, slurries and gases, particularly where high pressures, high temperatures or corrosive environments are involved. As a result of the aesthetic properties of stainless steel, pipe is often use in architectural applications.

Compared to chromium-nickel austenitic stainless steels, 316L stainless steel offers higher creep, stress to rupture and tensile strength at elevated temperatures.

In high temperature environments, 316 stainless steel tends to outperform 304.

Stainless Steel 304 Flanges

?The?ASTM A182 F304 Flanges?could be cleaned easily with a mild detergent. Despite undergoing repeated cleaning processes, these flanges won¡¯t wear away, an ability it exhibits due it its good wear resistance properties. Moreover, since grade 304 is an alloy that can be easily formed into various shapes, it is easily manufactured into any type of?ASME SA182 F304 Pipe Flange?such as a weld neck flange or an?Inox 304 Slip On Flange.

Alloy 347H (UNS S3409) stainless steel plate is the higher carbon (0.04 – 0.10) version of the alloy. It was developed for enhanced creep resistance and for higher strength at temperatures above 1000°F (537°C). In most instances, the carbon content of the plate enables dual certification.
