SS 904L Pipe Fittings

SS 904L Pipe Fittings are used in piping systems to connect straight pipe or tubing sections. The main use of fitting is to make the pipe or the tube adaptable to different sizes or shapes. SS 904L Pipe Fittings Manufacturers are also used for other purposes such as regulating or measuring fluid flow. The term plumbing is generally used to describe conveyance of water, gas, or liquid waste in ordinary domestic or commercial environments, whereas piping is often used to describe high-performance conveyance of fluids in specialized applications. The term tubing is sometimes used for lighting-with piping, especially types that are flexible enough to be supplied in coiled form.


It is basically a non-stabilized austenitic stainless steel with low carbon content offering resistance to strong reducing acids, such as sulfuric acid. Apart from that SS904L also exhibits resistant to stress corrosion cracking and crevice corrosion. It is highly pure with very less sulfur content and high amounts of expensive ingredients such as molybdenum and nickel.It is comparatively expensive, most of application of grade 904L are replaced by low-cost duplex stainless steel 2205. It is a low carbon, high alloy austenitic stainless steel which is surprisingly non-magnetic in all conditions. It is known for excellent formability and weldability. It is excellently tough even at cryogenic temperatures. This is due to high chromium content that promotes and maintains a passive film, which protects the material in corrosive environment. Its maximum service temperature is at 450°C.This alloy cannot be hardened by heat treatment. It is susceptible to hot cracking and any standard welding is employed. Common applications take advantage of 904L’s corrosion resistance. Grade 904L is widely used in acid processing plants, pulp and paper operations, equipment for cooling seawater, oil refining, and environmental equipment. The chemical processing industry makes extensive use of 904L stainless steel due to its broad corrosion resistance.

Special Properties

  • SS904L work hardens easily. This is usually minimized by slow speeds and positive feeds. Chip breakers are used to overcome problems with long draggy chips.
  • Common fusion and resistance method is employed for welding. Filler metal of equal or higher alloy content is used to get maximum corrosion resistance.
  • Hot working on this alloy is done on uniform heating. It is advisable not to work the material at less than 1800 F. Full annealing should follow any hot work to reattain maximum ductility and corrosion resistance.
  • Annealing is done at 1920-1990 F (1050-1090 C) followed by rapid cooling.
  • This alloy does not respond to heat treatment. It may only be hardened by cold reduction.

Typical Applications of SS 904L Pipe Fittings Include :

  • Wiring in electrostatic precipitators
  • Oil refinery components
  • Seawater cooling devices
  • Gas scrubbing plants
  • Pulp and paper processing industries
  • Acetic, phosphoric and sulphuric acid processing plants

The Processing of steel carp and alloy together leads to the production of SS 904L. The amount of Alloy mixed decides the capability of the Steel works.

But still they are following steps:

1. Step one is to melt the metal including, alloy and non-alloy into an electric arc furnace and later on adding the chemical energy like carbon, ferrosilicon, oxygen or fuel gas mixtures to speed up the process

2. After the melts process is done. The melts still is further processed in AOD which is Argon-Oxygen Decarburization. In which the carbon content is reduced and the mixture of Argon and Oxygen is added.

3. If we need the low amount of Argon and oxygen then melted steel is added to the VOD which is Vacuum Oxygen Decarburization. And then melted steel is poured on the ladle.
