Stainless Steel 316 is an austenitic stainless grade with 4% molybdenum in its composition. The content of chromium, nickel and molybdenum makes stainless steel 316 stronger, corrosion resistant and ductile.

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.

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]

SMO 254 ERW pipe is used where the properties and corrosion resistance of steel are required. The high molybdenum and chromium content also makes SMO 254 square tube highly resistant to acids that can cause pitting.

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.

304/304L is a versatile stainless steel widely used in the manufacture of equipment and components that require a good combination of properties (corrosion resistance and formability). 304 stainless steel is produced in accordance with the American ASTM standard stainless steel grade a. 304 contains 19% chromium and 9% nickel. 304 is the most widely used stainless steel, heat-resistant steel, utility steel, and steel industry. Used in food production equipment, general chemical equipment, nuclear energy, etc. In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 12% chromium.

Stainless steel flange not only refers to a kind of stainless steel flange, but also represents more than 100 kinds of industrial stainless steel flanges. Each type of stainless steel has good performance in its specific application field. First, the purpose of flange shall be clarified, and then the correct stainless steel grade shall be determined. Common stainless steels are 304, 304L, 316, 316L, etc. They all contain chromium, nickel and other chemical components. For example, the addition of molybdenum can further improve the atmospheric corrosion, especially the corrosion resistance to the atmosphere containing chloride.

The large amount of chromium content in 309 Steel U Bolts and 309 Steel T Bolts produces their resistance to corrosion and their non-magnetic characteristic which finds applications in a variety of industries.

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.

Stainless Steel 904L Sheets, which is one of many stainless steel grades that can be purchased at our firm.

These flanges have excellent corrosion resistance compared to 304 grade stainless steel flanges. We manufacture stainless steel 316L blind flanges of high quality for use in piping in critical conditions. This is an austenitic stainless steel.

Stainless Steel 904L Sheet possesses high tensile strength and toughness. Stainless Steel 904L Sheet contains 28% nickel content, 23% chromium content, and 5% molybdenum content.

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.

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.

S32750 (2507) is a duplex stainless steel that combines many of the excellent properties of ferritic and austenitic steels. Due to its high chromium and molybdenum content, it exhibits excellent resistance to pitting, crevice and uniform corrosion. The two-phase microstructure ensures that the steel has high resistance to stress corrosion cracking and high mechanical strength. In addition, it also has the characteristics of strong resistance to chloride pitting, high thermal conductivity and low thermal expansion coefficient.

Bright Annealed (BA) is produced by heat-treating (annealing) steel with a controlled atmosphere furnace. After heat-treatment, the steel has a reflective, mirror-like appearance, but may also have some imperfections and cloudiness. BA stainless steel can be buffed to attain a more reflective finish, and is often specified for applications where a highly reflective surface is desired.
