AISI 904L Welded Pipe according to specification ASTM A312. Though the content of carbon is lower, these pipes could be used for high temperature applications.
The significant inclusion of nickel to the alloy of ASME SA 312 TP904L makes it possible for the pipes to have an outstanding performance even in elevated settings. Along with being a non-magnetic alloy, the A249 UNS N08904 Seamless Welded Pipe Tube also exhibits good resistance to stress related corrosion cracking. The presence of molybdenum in the ASTM A312 TP 904L Pipe reduces the occurrence of crevice corrosion. Along with being used in applications between moderate to high temperatures, the 904L SS Pipe is primarily useful for general corrosion applications.
More About 904L:
The ASTM A312 TP 904L material is labeled as a super austenitic stainless steel alloy because of its corrosion resistance properties. Because the alloy has a higher content of molybdenum in its alloy, the ASME SB677 TP 904L Square Pipe exhibits superior resistance to localized attack, specifically from corrosion forms like pitting and crevice corrosion. Copper content in the ASTM B673 UNS N08904 ERW Pipe greatly improves resistance to strong reducing acids, especially (H2SO4) sulphuric acid. With excellent weldability and formability 904L also maintain non-magnetic state in all conditions. 904L Stainless Steel Pipe provides excellent toughness , even down to cryogenic temperatures with its austenitic structure.

Incoloy 926(UNS N08926/W.Nr. 1.4529) stainless steel is a superaustenitic (highly alloyed) stainless steel formulated for primary forming into wrought products. N08926 is the UNS number for this material. Alloy 926 is the common industry name. 1.4529 grade stainless steel has a high tensile strength which can be classified as nickel alloys (according to American standards). Delivered in the supersaturated state exhibits resistance to intercrystalline, pitting, and stress corrosion, salt, sea water, chloride, sulfuric acid, phosphoric acid and other aggressive chemicals in high concentrations in liquid and gaseous form.Materials of 1.4529 grade, except high chemical resistance, can work at elevated temperatures while maintaining adequate mechanical properties.Ignoring the high content of nickel and chromium, the standard also specifies a relatively large amount of Molybdenum and Nitrogen, which is particularly worthwhile when selecting grade from the related group of high alloy steels.Significantly higher percentages of Nitrogen and Molybdenum contribute to limiting the creation of intermetallic phases, as well as improving the impact resistance.

Alloy 904L (N08904) is a super austenitic stainless steel that is designed for moderate to high corrosion resistance in a wide range of process environments. The combination of high chromium and nickel contents, coupled with additions of molybdenum and copper, assure good to excellent corrosion resistance. With its highly alloyed chemistry—25% nickel and 4.5% molybdenum, 904L provides good chloride stress corrosion cracking resistance, pitting and general corrosion resistance superior to 316L and 317L molybdenum enhanced stainless steels. Alloy 904L was originally developed to withstand environments containing dilute sulfuric acid. Consequently, it has proven successful in handling a number of other process chemicals as well as pressure equipment in the chemical processing industry.
904l stainless steel pipe is a kind of ultra high strength steel pipe, which is more than the ordinary carbon steel pipe. The tube is made of the most advanced seamless manufacturing process, and its quality is higher than the carbon steel pipes. In addition, it is also resistant to corrosion and has excellent mechanical properties.
904L stainless steel pipe is a kind of alloy steel, which has high strength and ductility. It is widely used in the fields of petroleum, chemical, thermal power, energy conservation and environmental protection, shipbuilding and so on.
The sizes of 904L stainless steel pipes are as follows:
1. OD: φ90-φ1500mm
2. WT: 1/4-6.0mm
There are numerous austenitic stainless steel pipes and ASTM B677 UNS N08904 is one of them. 904L Pipe is a non-stabilized austenitic stainless steel with low carbon content. This high alloy austenitic stainless steel is added with copper to improve its resistance to strong reducing acids, such as sulphuric acid. The steel is also resistant to stress corrosion cracking and crevice corrosion. 904L Stainless Steel Pipe has good formability, weldability and toughness. It can be formed by cold working and heat treatment. Annealing of the pipe is done at 1040-1065°C (1900-1950°F) followed by rapid cooling to prevent crystallization of the grain boundary precipitates.
904L stainless steel pipe is one of the most advanced materials in the world. It is a high-performance heat treatment alloy, which is used to produce high-quality products such as chemical equipment and mechanical parts.
904L stainless steel pipe is a kind of austenitic stainless steel with extra low carbon content, which has excellent corrosion resistance, high mechanical properties and good weldability, which are widely used in chemical equipment and ships.
904L stainless steel pipes are available in both seamless and welded forms. Seamless pipes are generally used in high-pressure applications while welded pipes are used in lower-pressure applications. Both types of pipes have their own advantages and disadvantages.
Seamless stainless steel pipes are made from a single piece of metal, so they don’t have any seams or joints. This makes them much stronger and more durable than welded pipes. They can also handle higher pressures since there’s no risk of the seams leaking. However, seamless pipes are more expensive and difficult to manufacture than welded pipes.
Welded stainless steel pipes are made by joining together pieces of metal using a welding process. This makes them less strong than seamless pipes but they’re much cheaper to produce. Welded pipes are often used in low-pressure applications such as water pipe systems.
904L is a low carbon, high alloy austenitic stainless steel. It has excellent formability, weldability and corrosion resistance. Due to its high chromium and nickel content, it is also known as “super austenitic stainless steel”. 904L pipes and tubes are widely used in chemical processing, petrochemical and oil & gas industries.
904L stainless steel pipes and tubes offer superior corrosion resistance in aggressive environments. In addition, they have excellent weldability and formability. 904L pipes and tubes can be used in many applications including:
– Chemical processing equipment
– Petrochemical industry
– Oil and gas industry
– Marine environments
– Desalination plants
ASTM B677 UNS N08904 904L Stainless Steel Seamless Pipe is an austenitic stainless steel designed for moderate to high corrosion resistance. The alloy contains high levels of chromium and nickel with additions of molybdenum and copper. This combination provides good corrosion resistance in most environments, with superior resistance to pitting and crevice corrosion in chloride-bearing conditions. The alloy is also resistant to stress-corrosion cracking and intergranular corrosion.
904L stainless steel pipe is mainly used in the food, chemical, and pharmaceutical industries due to its high corrosion resistance. It is also used in the construction industry for its strength and durability.
Alloy 904L stainless steel pipe is a medium-carbon high-chromium alloy with excellent corrosion resistance. It has good plastic deformation, resistance to impact and wear, as well as good weldability and toughness.
The pipe is used in water distribution systems, oil and gas pipelines, power transmission lines, petrochemical plants and refineries, chemical plants and other industrial applications.
