Introduction of 904L ASTM B677 TP 904L Stainless Steel Seamless Pipe

UNS N08904, commonly known as 904L stainless steel, is a low carbon austenitic nickel-chromium stainless steel with additions of Molybdenum and copper.

Due to combination of high content of chromium, nickel, molybdenum and copper, Stainless steel 904l exhibits greater resistance to putting and crevice corrosion and to general corrosion to reducing acids.

Grade 904L stainless steel is a non-stabilized austenitic stainless steel with low carbon content. This high alloy 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. Grade 904L is non-magnetic, and offers excellent formability, toughness and weldability.

Possible Alternative Grades

The suitable alternatives to 904L stainless steels are tabulated below:

Possible alternative grades to grade 904L stainless steels

Grade	Reasons for choosing grade 904L
316L	A lower cost alternative, but with much lower corrosion resistance.
6Mo	A higher resistance to pitting and crevice corrosion is needed.
2205	A very similar corrosion resistance, with the 2205 having higher mechanical strength, and at a lower cost to 904L. (2205 not suitable for temperatures above 300°C.)
Super duplex	Higher corrosion resistance is needed, together with a higher strength than 904L.

Corrosion Resistance

Grade 904L stainless steels have excellent resistance to warm sea water and chloride attack. The high resistance of grade 904L against stress corrosion cracking is due to the presence of high amounts of nickel in its composition. Moreover, the addition of copper to these grades develops resistance to sulphuric acid and other reducing agents in both aggressive and mild conditions.

The corrosion resistance of grade 904L is intermediate between super austenitic grades, with 6% molybdenum content, and standard 316L austenitic grades. Grade 904L is less resistant to nitric acid than grades 304L and 310L, which are free of molybdenum. This steel grade needs to be solution treated following cold working, to achieve maximum stress corrosion cracking resistance under critical environments.

Heat Resistance

Grade 904L stainless steels offer good oxidation resistance. However, the structural stability of this grade collapses at high temperatures, particularly above 400°C.

Heat Treatment

Grade 904L stainless steels can be solution heat-treated at 1090 to 1175°C, following by rapid cooling. Thermal treatment is suitable for hardening these grades.

Welding

Welding of grade 904L stainless steels can be performed using all conventional methods. This grade does not require pre-heat and post-weld heat treatments. Grade 904L can be subjected to hot cracking in constrained weldment. Grade 904L electrodes and rods are used for welding grade 904L steels according to AS 1554.6.

Fabrication

Grade 904L stainless steels are high purity steels with low sulphur content. They can be machined using any standard methods. These grades can be readily bent to a small radius under cold conditions. Although subsequent annealing is not required in most cases, it should be carried out when the fabrication is performed under severe stress corrosion cracking conditions.

Machinability

Slow speeds and positive feeds will minimize this alloy's tendency to work harden and glaze. Use chip breakers where possible to overcome problems with long draggy chips.

Hot Working

Hot work should proceed after uniform heating to 2000-2200 F. Doe not work the material at less than 1800 F. Full annealing should follow any hot work to re attain maximum ductility and corrosion resistance.

Cold Working

Although higher forces are required, 904L will respond in a similar fashion to other austenitic stainless steels like 304, 316 or 317. Most common operations can be successfully performed.

Annealing

1920-1990 F (1050-1090 C), rapid cooling.

Hardening

This alloy does not respond to heat treatment.. It may only be hardened by cold reduction.

Applications

Some of the major applications of grade 904L stainless steels 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
