Stainless steel rods are popular for their corrosion resistance and are widely used in the construction of building foundations, bridges and marine environments. 304/304L Stainless Steel Round, an economical grade stainless steel ideal for all applications requiring strength and superior corrosion resistance.

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.

ASTM A276 Type 309 is a material grade specification for cold-finished or hot-finished bars in 309 stainless steel, available in form of rounds, square, hexagons and other hot rolled extruded shapes. Boltport uses 309 bar stock to ASTM A276 specifications for manufacturing stainless steel 309 bolts, nuts, screws, studs, threaded rods, other fasteners and bar stock components for general engineering purposes.

Type 304 stainless steel is named for its composition, which includes 18% chromium and 8% nickel. This stainless steel has good formability and weldability. Due to its composition, stainless steel 304 flanges are highly corrosion resistant and fairly durable.

SS316 stainless steel has more carbon than SS316L. Nickel and molybdenum are the main chemical ingredients which are used in manufacturing process of stainless steel SS316 pipes. With adding molybdenum in the producing process, it effectively improves alloy corrosion resistance, specifically in the environment that is highly exposed to crevice corrosion in chloride based environments.

Regarded to be the most basic stainless steel, the Stainless Steel 304 Flanges are also known as 18-8 grade with a higher content of chromium and low carbon content. The presence of low carbon content in the alloy restricts the formation of carbide precipitates during welding along with minimizing the 304 Stainless Flanges from being susceptible to intergranular corrosion.

Stainless steel grade 304 is the most commonly used stainless steel. Stainless steel grade 304N has better corrosion resistance than grade 302, and is mostly non-magnetic in nature; however when cold worked it acquires a slightly magnetic quality.

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 surfaces of these parts have a mottled appearance due to general corrosion. Additionally, they weaken the alloy and require frequent replacement to prevent catastrophic effects. Because the alloy has good resistance to general corrosion or uniform erosion, from a financial standpoint, the industry can use 304 stainless steel welded fittings without denting their pockets.

Steel flanges provide an easy access for cleaning, inspection or modification. They usually come in round shapes but they can also come in square and rectangular forms. The flanges are joined to each other by bolting and joined to the piping system by welding or threading and are designed to the specific pressure ratings; 150lb, 300lb, 400lb, 600lb, 900lb, 1500lb and 2500lb.

A flange can be a plate for covering or closing the end of a pipe. This is called a blind flange. Thus, flanges are considered to be internal components which are used to support mechanical parts.

The balanced austenitic structure of grade 304 enables deep drawing without intermediate annealing, which makes this grade dominant in the manufacture of drawn stainless steel parts such as sinks, hollowware, and pans.

It is designed with a combination of impact toughness resistance to chloride stress corrosion cracking, and pitting and crevice corrosion with strength that is twice that of the stainless steel 300 series.

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.

Steel flanges provide an easy access for cleaning, inspection or modification. They usually come in round shapes but they can also come in square and rectangular forms. The flanges are joined to each other by bolting and joined to the piping system by welding or threading and are designed to the specific pressure ratings; 150lb, 300lb, 400lb, 600lb, 900lb, 1500lb and 2500lb.

A flange can be a plate for covering or closing the end of a pipe. This is called a blind flange. Thus, flanges are considered to be internal components which are used to support mechanical parts.

Stainless steel flange has good performance and scientific materials. General metal materials react with air in a humid environment, changing the original metal properties.

317L is non-magnetic in the annealed condition but may become slightly magnetic as a result of welding.Fittings supplied under this specification shall be examined visually for surface discontinuities, surface checks, and mechanical marks.

As a butt weld fitting, it works with lap flanges. The use of stainless steel short pipe ends and lap flanges can effectively reduce pipeline maintenance costs. In stainless steel piping systems or advanced systems, we can choose low-grade lap flanges with stainless steel short pipe ends as an alternative to flanged connections instead of butt-welded flanges, effectively reducing manufacturing costs.

Type 304L is a variant of Type 304 with a low carbon content to improve weldability and reduce the risk of reduced corrosion resistance around the weld. The yield strength and tensile energy of Type 304L are also slightly reduced compared to Type 304.

304/304L stainless steel has good cold and hot working properties, and can use a variety of cold and hot working processes to produce metallurgical products such as forgings, bars, wires, plates, strips and wires. The hot working temperature range is 900-1180 ¡æ. Cold working is relatively easy and not particularly difficult, because these two steels are easy to cold harden, and when the cold deformation is too large, intermediate annealing is required to facilitate further processing.

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.
