Product Introduction

ASTM A240 Stainless Steel 904l Plate is a super austenitic stainless steel designed for moderate to high corrosion resistance in a wide range of environments. The addition of copper in N08904 gives it excellent corrosion resistance to nickel stainless steel, sulfuric acid, phosphoric acid, acetic acid, hydrochloric acid, etc. 904L Steel Plate also has excellent resistance to chloride attack and general corrosion and pitting. Our company is a 904L supplier with 15+ export experience, contact us for more information and free quotes!
