We are a 904L stainless steel casting manufacturer and supplier in China. We offer 904L Alloy steel casting with ISO 9001:2015. And the most customers are from the USA. German, Spanish.
What is 904L stainless steel? 904L (00Cr20Ni25Mo4.5Cu; UNS: N08904; EN: 1.4539) is one type of high alloy austenitic stainless steel with low carbon content. It is known for its strong 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 strong resistant corrosion properties, This low carbon version of 904L stainless steel casting also offers more benefits to users. Such as:
- 1.Non-magnetic
- 2.Stronger corrosion properties than Type 316L and 317L
- 3.Good resistance to sulphuric, phosphoric and acetic acids
- 4.High resistance to crevice and stress corrosion cracking
- 5.Excellent formability and weldability
904L stainless steel chemical composition includes the following:
| Content | Ni | Cr | Mo | Mn | Cu S | Si | S | N | P | Fe |
| 100% | 23-28 | 19-23 | 4-5 | 2 | 1-2.0 | 0.7 | 0.3 | 0.1 | 0.03 | Balance |
