Type 904L is a high alloy austenitic stainless steel that is known for its corrosion properties. This low-carbon version of Type 904 stainless steel also offers other benefits to users including:
Non-magnetic
Stronger corrosion properties than Type 316L and 317L
Good resistance to sulphuric, phosphoric, and acetic acids
High resistance to crevice and stress corrosion cracking
Excellent formability and weldability
Due to all of the benefits of using Type 904L stainless steel, it can be found in a number of applications in a wide variety of critical industries including:
Cooling equipment for seawater
Chemical processing of sulphuric, phosphoric, and acetic acids
Heat exchangers
Condenser tubes
Gas washing
Control and instrumentation
Oil and gas industry
Pharmaceutical production
Wiring in electrostatic precipitators
To be considered Type 904L, stainless steel must have a unique chemical composition that includes the following:
Fe balance
Ni 23-28%
Cr 19-23%
Mo 4-5%
Mn 2%
Cu S 1-2.0%
Si 0.7%
S 0.3%
N 0.1%
P 0.03%
All of the Type 904L stainless steel that Continental Steel supplies; meets typical manufacturing specifications including ASTM, EN, and more.
