DIN Standard Flanges SS UNS S31000 Pipe Flanges

ASTM A312 TP316 is a standard specification for seamless, straight-seam welded, and heavily cold worked welded austenitic stainless steel pipes used in high-temperature and general corrosive service applications. The 316 Seamless Industrial Steel Pipe is made from a combination of chromium, nickel, and molybdenum, which gives SS 316 Seamless Tube excellent resistance to corrosion and rust.

ASME B36.19M is the standard specification for stainless steel pipes, which specifies the dimensions, tolerance, and manufacturing requirements for both welded and seamless pipes.

AL6XN is a superaustenitic stainless steel with outstanding resistance to chloride pitting, crevice corrosion and stress corrosion cracking. AL6XN is a 6 moly alloy that was developed for and is used in highly aggressive environments. It has high nickel (24%), molybdenum (6.3%), nitrogen and chromium contents that give it excellent resistance to chloride stress corrosion cracking, chloride pitting, and exceptional general corrosion resistance. AL6XN is primarily used for its improved pitting and crevice corrosion resistance in chlorides. It is a formable and weldable stainless steel.

SMO 254 Pipes can withstand high mechanical stress and Alloy 254 SMO Pipe high pressure work in high temperatures and corrosive environments.

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The UNS S31803 (ASTM F51) specification has been largely superseded by UNS S32205 (1.4462, ASTM F60).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).

The ASTM A312 TP304 Pipe is used for high pressure and high temperature applications because of the high operating temperature of 870 degrees Celsius and the strength. The minimum yield strength of the SS UNS S30400 ERW Pipe is 205MPa and the minimum tensile strength is 515MPa. The applications include commercial, industrial, domestic and general corrosive services. The ASME SA312 Grade 304 Welded Pipe is one of the most cost effective stainless steel pipes in the market.

Grade 304 stainless steel is generally considered the most common austenitic stainless steel.

The two most common stainless steel grades are 304 and 316. The key difference is the addition of molybdenum, an alloy which drastically enhances corrosion resistance, especially for more saline or chloride-exposed environments.

While both 304 and 316 stainless steels are strong, the addition of molybdenum to 316 gives it a slight advantage over 304 in strength. With 316 stainless steel, you can expect better resistance to chloride corrosion and pitting than 304 stainless steel, as well as higher strength at elevated temperatures.

The fitting of the ASTM A105 grade are produced in seamless forged carbon steel specification. ASTM A105 Fittings are designed with a chemical content of nickel, chromium, molybdenum, copper, and vanadium. These fitting help in connecting different piping grades in the oil and gas industry.

304 also contains 8-10.5% nickel (Ni). It is added to make the austenite structure more stable at room temperature. Nickel also improves high temperature oxidation resistance, making the steel resistant to stress corrosion cracking. Where the steel is to be stretch formed, a lower percentage (8%) of nickel should be chosen. Higher percentages are better (9% or more) if the steel is to be deep drawn.

Grade 304 stainless steel is the standard “18/8” stainless steel; it is the most versatile and widely used stainless steel available in a wider range of products, forms and finishes than any other. It has excellent forming and welding characteristics.

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.

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.

We stock an extensive inventory of high-quality standard and special grade of seamless stainless steel tube and welded stainless steel tubing.

It is ideal for food processing, chemical processing, and fluid transportation. The most common uses for stainless steel forged fittings are in food and fluid processing, as well as chemical applications. Stainless Steel 304 is the best choice for forged fittings because of its inherent properties.
