AISI 904L Stainless Steel Chemical Composition Properties, Grade, Table and Document

AISI 904L austenitic stainless steel containing high alloy has exceptional corrosion resistance especially towards acidic environments. By its chemical composition, it has a lot of chromium, nickel, molybdenum and copper as its principal elements which determine its efficiency in different uses: chemistry, pharmacy, marine applications and etc. With highest level of pitting resistance this grade successfully avoids the crevice corrosion and stress corrosion cracking. Typically utilized in the form of heat exchangers, tanks and piping, AISI 904L allows for not only all the needed durability but also years of usage. Its specifications as well as the mechanical qualities meet the AISI's and the ASTM International's standards. Besides, tables and documents that are comprehensive with regard to its composition, properties and grades, can be readily found in the engineering and used for reference purposes.

AISI 904L Stainless Steel Chemical Composition And Grade Table

AISI 904L stainless steel is a special high alloy, austenitic stainless steel that is characterized by remarkable corrosion resistance in the type of environments considered harsh. Cr, Ni, Mo and C like this, usually its chemical composition is hight. The actual percentage may slightly vary between manufacturers, but mostly it consists of about 20-25% chromium, 4.5-5.5% nickel, 23-28% molybdenum, and trace amounts of carbon (unless you count dietary imbalances). Such mixture of features is responsible for outstanding corrosion resistance against acids mostly from sulfuric acid source, chlorides, and pitting corrosion. AISI 904l has wide application in sectors such as chemical processing, pharmaceuticals, and offshore oil and gas.
