One of the major concerns about the SS 304 Fitting is its low cost compared to other high end alloy material counterparts.All A403 gr WP304 Buttweld Elbow and 304 Pipe Fittings should experience heat-treatment.

Another industry that uses this alloy is the food and beverage industry, which uses acetic acid as a preservative. Acetic acid is an organic acid that is corrosive to carbon steel.

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.

The difference between 304 and 304L stainless steel is that 304L has a .03 max carbon and is good for welding whereas 304 has a mid range level of carbon.

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.

304 SS Weld Fittings & Stainless Steel 304 Pipe Fittings must contain more than 18% chromium and more than 8% nickel. ASTM A403 WP304 Fittings are buttweld fittings made for austenitic stainless steel applications with forged material.

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.

The austenitic stainless steel 6Mo was developed on the basis of alloy 904l/1.4539. However, the molybdenum content at 6Mo is increased to 6.5%. 6Mo has excellent general corrosion resistance and improved pitting and crevice corrosion resistance. Resistance to stress corrosion cracking is also improved. It is often referred to as super austenitic stainless steel.

There are also 310S and 310H grades of flanges based on the carbon content. These flanges are used in high temperature service with high corrosion prone environments because of the high temperature tolerance and high oxidation corrosion resistance.

Fully austenitic welds are more prone to cracking during welding. For this reason, Type 316 and Type 316L “matching” filler metals are formulated to cure with a small amount of ferrite in the microstructure to minimize cracking susceptibility.

254 SMO bolts are made from (UNS S31254) austenitic stainless steel which is very resistant to pitting and crevice corrosion due to its high molybdenum content. This metal is designed for use in halide-containing environments, such as seawater.

254 SMO is a high alloy austenitic stainless steel developed for use in seawater and other corrosive chlorine-containing media. The steel has the following properties: excellent resistance to pitting and crevice corrosion, high resistance to general corrosion and high resistance to stress corrosion cracking. 254 SMo / EN 1.4547 / UNS S31254 / 6Mo are generally used in pumps, valves, chokes, pipes/flanges and washers and have a high resistance to general corrosion.

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.

Seamless steel pipes have a hollow section and are used in large quantities as pipelines for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, steel pipe is lighter in flexural and torsional strength and is an economical section steel.
