The 904L is a high-alloy, low-carbon, austenitic stainless steel that is highly resistant to corrosion in dilute sulfuric acid and is designed for harsh environments. With high chromium content and enough nickel content, the addition of copper makes it have strong acid resistance, and it is highly resistant to chloride interstitial corrosion and stress corrosion cracking. It is not prone to pitting and cracking. The etching ability is slightly better than other steel grades. It has good workability and weldability and can be used in pressure vessels.


Application area:

* Scrubbers and fans in organic acid processing systems.

* Pharmaceutical factory: centrifuges, reactors, etc.

* 904L, a strong corrosive medium for dilute sulfuric acid, is a matched steel grade.
