We are 904 Alloy steel casting manufacturer and supplier.We offer 90l stainless steel casting products from China.
904 (00Cr20Ni25Mo4.5Cu; UNS: N08904; EN: 1.4539) is one type of a high alloy austenitic stainless steel with low carbon content. It is known for its stong resistant corrosion properties.It has good activation-passivation conversion ability, excellent corrosion resistance, good corrosion resistance in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid, phosphoric acid. It has good processability and weldability, and can be used in pressure vessels.It is specially designed for corrosion conditions and in demanding environments
Beside the stong resistant corrosion properties, This low carbon version of 904L stainless steel casting also offers more benefits to users.Such as:
Stronger corrosion properties than Type 316L an 317L
Good resistance to sulphuric, phosphoric and acetic acids
High resistance to crevice and stress corrosion cracking
Excellent formability and weldability
Type 904L, a stainless steel must have a unique chemical composition that includes the following:
Cu S 1-2.0%
* Petroleum, petrochemical equipment, such as reactors in petrochemical equipment.
* Storage and transportation equipment for sulfuric acid, such as heat exchangers.
* Power plant flue gas desulfurization device, the main use parts are: tower body of the absorption tower, flue, door panel, internal parts, sprinkler system, etc.
* Washers and fans in organic acid treatment systems.
* Seawater treatment equipment, seawater heat exchangers, paper industry equipment, sulfuric acid, nitric acid equipment, acid production, pharmaceutical industry and other chemical equipment, pressure vessels, food equipment.
*Pharmaceutical plants: centrifuges, reactors, etc.
*Plant food: soy sauce cans, cooking wine, salt shakers, equipment and dressings.
* Strongly corrosive medium to dilute sulfuric acid.
