• Product Description

904L uses, application scope and application fields are:
* Petroleum, petrochemical equipment, such as reactors in petrochemical equipment, etc.
* Storage and transportation equipment for sulfuric acid, such as heat exchangers, etc.
* The flue gas desulfurization device in power plants is mainly used in: the tower body of the absorption tower, the flue, the shutter, the internal parts, the spray system, etc.904L (N08904,,14539) super austenitic stainless steel contains 14.0-18.0% chromium, 24.0-26.0% nickel, 4.5% molybdenum.
904L super austenitic stainless steel is a low carbon, high nickel, molybdenum austenitic stainless steel, which is the exclusive material of H·S company from France.
It has good activation – passivation conversion ability, excellent corrosion resistance, in non-oxidizing acid such as sulfuric acid, acetic acid, formic acid, phosphoric acid has good corrosion resistance, in neutral medium containing chloride ion has good pitting resistance, and has good crack corrosion resistance and stress corrosion resistance.
Applicable to all concentrations of sulfuric acid below 70℃, under normal pressure any concentration, any temperature of acetic acid, and formic acid and acetic acid in the mixture of corrosion resistance is also very good.

is a low carbon, high-alloy austenitic stainless steel with excellent corrosion resistance in dilute sulfuric acid. It is designed for harsh corrosion conditions.
Has the high chromium content and plenty of nickel content, the addition of copper makes it have strong ability to resist acid, especially for chloride clearance corrosion and stress corrosion cracking are highly resistant, not easy to appear, erosion and fracture pitting resistance slightly better than other steel grade, good machinability and weldability, can be used for pressure vessels.

Since the carbon content of 904L is very low (Max. 0.020%), there will be no carbide precipitation during normal heat treatment and welding.
This eliminates the risk of intergranular corrosion that normally occurs after heat treatment and welding.Due to the high chromium, nickel, molybdenum content and the addition of copper, 904L can be passivated even in reducing environments, such as sulfuric acid and formic acid.
The high nickel content makes it have a low corrosion rate in the active state.In the concentration range of 0 to 98% pure sulfuric acid, 904L can be used at temperatures up to 40 degrees Celsius.Its corrosion resistance is very good in pure phosphoric acid in the concentration range of 0~85%.In industrial phosphoric acid produced by wet process, impurity has a strong effect on corrosion resistance.Of all the phosphoric acids, 904L has superior corrosion resistance to ordinary stainless steel.In highly oxidizing nitric acid, 904L has poor corrosion resistance compared to highly alloyed steels without molybdenum.In hydrochloric acid, the use of 904L is limited to lower concentrations of 1-2%.It’s in this concentration range.The corrosion resistance of 904L is better than that of conventional stainless steel.904L steel has high resistance to pitting corrosion.It also has excellent crevice corrosion resistance in chloride solutions.The high nickel content of 904L reduces the corrosion rate in pits and crevices.
Ordinary austenitic stainless steels may be sensitive to stress corrosion at temperatures above 60 ° C in a chloride-rich environment, and this sensitivity can be reduced by increasing the nickel content of the stainless steels.Due to its high nickel content, 904L is highly resistant to stress corrosion cracking in chloride solutions, concentrated hydroxide solutions and hydrogen sulphide-rich environments.
