  • What is 904L Stainless Steel Couplings?

An Alloy 904L Stainless Steel couplings are a device used to connect two shafts together at their ends for the purpose of transmitting power. Couplings do not normally allow disconnection of shafts during operation, however there are torque limiting couplings which can slip or disconnect when some torque limit is exceeded.

904l Stainless Steel Couplings Equivalent Grades

Grade

Features of alternative grades of SS 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.

The steel shall conform to the requirements as to chemical composition specified.
The material shall conform to the mechanical properties specified.

SUS 904L Couplings Heat Resistance

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

AISI 904L Couplings Heat Treatment

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

SS 904L Couplings Fabrication

Grade 904L stainless steel Couplings 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.

904L Stainless Steel Couplings producing through Cold forming

904L stainless steel Couplings is quite ductile and forms easily. The addition of molybdenum and nitrogen implies more powerful processing equipment may be necessary when compared with the standard 304/304L grades.

Stainless Steel 904L Couplings Machining

The cold work hardening rate of Alloy 904L Couplings makes it less machinable than 410 and 304 stainless steel Couplings.

904L Couplings Welding

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

Alloy 904L Couplings Hot Forming

Working temperatures of 1562 – 2102°F (850 –1150°C) are recommended for hot working processes. It is important that the entire workpiece be quenched from temperatures above 2012°F (1100°C). In the event of partial heating or cooling below 2012°F (1100°C), or if the cooling has been too slow, hot working should always be followed by a solution anneal and quenching. 904L Couplings should be solution annealed at 1940 – 2084°F (1060 –1140°C).

904L Stainless Steel Couplings Applications & Usage:

Some of the major applications of grade stainless steel 904L Couplings include:

  • SAE 904L Couplings for Air Pollution Control- scrubbers for coal-fired power plants
