The 904L grade is known for its excellent resistance to corrosion across a variety of harsh environments, making it a preferred choice in multiple industrial applications.
Overview of SS 904L Alloy
Stainless Steel 904L is a non-stabilized austenitic alloy that contains a low percentage of carbon. It is enriched with copper, which enhances its resistance to strong reducing acids such as sulfuric acid. This stainless steel grade is highly resistant to crevice corrosion and stress corrosion cracking.
904L is also non-magnetic in nature and exhibits excellent formability, toughness, and weldability. The alloy contains essential elements such as nickel and molybdenum, making it a cost-effective yet high-performance material for corrosive applications.
Salient Features of SS 904L Plates
The plates fabricated from SS 904L offer numerous valuable features that contribute to their wide usage in industries. These include:
High tensile strength, outstanding dimensional accuracy, corrosion resistance, rugged construction, high durability, surface finish, flexibility, longevity, and user-friendliness.
Moreover, the alloy has the capacity to withstand multiple forms of corrosion, including pitting, crevice corrosion, oxidation, stress corrosion cracking, and general corrosion. These attributes make it ideal for use in aggressive and demanding environments.
