UNS N08904 Seamless Pipes are available in sizes ranging from 1/2″ NB to 8″ NB whereas ERW Pipes or Welded Pipes are available in between 1/2″ NB to 24″ NB (6″ NB – 100″ NB).

904L steel is commonly known as 2RK65 Stainless Steel, RVS 904L, Uranus B6, SEW 400, vdtüv 421, Inox 904L, etc. 904L Steel is a low carbon high alloy austenitic stainless steel (x1nicrmocu 25 20 5 / z2ncdu25 20) which is widely used in applications where the corrosion properties of AISI 316L and AISI 317L are not adequate.
Stainless Steel 904L (1.4539) with UNS N08904 is a non-stabilized low carbon high alloy austenitic stainless steel. Oshwin Overseas offer 904L Seamless and Welded SS 904l pipe in different sizes, grades, diameters and types like seamless, welded & fabricated. These SS 904L (Alloy 904L) Pipes has a corrosion resistance to a wide range of corrosive environments. AISI 904L (SUS 904L) is non-magnetic in all conditions and has excellent formability and weldability. The austenitic structure of AISI 904L Stainless Steel (сталь 904L) also gives this grade excellent toughness, even down to cryogenic temperatures.

Oshwin Overseas is a specialised manufacturer of the following types of 904L steel pipe:

904L Pipe Corrosion Resistance

904L gives good resistance to both organic and inorganic acids.The addition of copper in 904L grade gives excellent corrosion resistance against nickel stainless steels , to sulphuric, phosphoric, acetic acids, hydrochloric acids, etc. It also gives a high resistance to pitting in chloride solutions, a excellent resistance to both crevice and stress corrosion cracking.The 904L is much better  than austenitic stainless steels due to the higher alloying of nickel and molybdenum.The high percentage of  chromium content in 904L gives and maintains a passive film which protects the material in many corrosive environments.

904L Pipe Cold Forming

Cold forming 904L can be done easily. The composition of molybdenum and nitrogen implies more powerful processing equipment may be needed.Most of the time more common methods like cooling with air or water, etc is used.

904L  Pipe Hot Forming

Hot and heat forming should be done after uniform heating.Complete annealing should be done before any hot forming in order to retain maximum ductility and corrosion resistance property. It is very important that the whole process should be done above 1100°C.

904L Pipe Machining

The machining of  904L  requires  proper care to achieve the expected result. The cutting speed should be slow and proper care should be taken while doing so.
904L Pipe  Welding

The 904L material should be allowed to cool in between, preferably to below 150°C temperatures. To obtain good welding properties welded condition, filler material shall be used.Because of high thermal expansion, welding must be carefully planned in advance to ensure that distortion of the welded joint can be kept under control.
904L Pipe Heat Treatment

The heat treatment should be accompanied by cooling in water or air immediately. This treatment should be applied for both solution annealing and stress relieving from the 904L material.
