904L Stainless Steel Sheet
Lork Group is 904L Stainless Steel sheet supplier and exporter. 904L (UNS N08904) is a superaustenitic stainless steel designed for corrosion and pitting resistance in a wide range of process environments. It is used extensively in the chemical process industry including the production of phosphate-based fertilizers.
904L Stainless Steel sheet that is designed for moderate to high corrosion resistance in a wide range of process environments. The combination of high chromium and nickel content, coupled with additions of molybdenum and copper, assure good to excellent corrosion resistance.
We keep a selection of common sizes of 904L Stainless Steel sheet in stock. If you have high requirements for the delivery time of the plates, you can confirm with us request a quote.
