AISI 904L - UNS N08904 Bolts Nuts Studs Washers

Aanuraj mfgs Nuts studs & bolts from 904L, mainly for corossive environment.

Aanuraj Studs Bolts and Nuts are made from 1.4539 (UNS N08904 – 904L-SS2562) a high alloyed, acid-proof stainless steel, developed to resist corrosion in dilute sulphuric acid. The steel is very useful for details in marine environment, chemical and pharmaceutical industry plant and also for mfg of equipments, Valves and Pumps.

Alloy904L(UNS N08904) is a superaustenitic stainless steel 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.

904L stainless steel a “corrosion-resistant superalloy.” 904L differs from 316L because of extra ChromiumMolybdenum, Nickel, and Copper which gives it improved resistance to acids. 316L is considered a tougher, harder, “marine grade” steel, but it does not have luster and acid resistance of 904L

Grade 904L stainless steel is a non-stabilized austenitic stainless steel with low carbon content. This high alloy stainless steel is added with copper to improve its resistance to strong reducing acids, such as sulphuric acid. The steel is also resistant to stress corrosion cracking and crevice corrosion. Grade 904L is non-magnetic, and offers excellent formability, toughness and weldability.

Grade 904L contains high amounts of expensive ingredients, such as molybdenum and nickel.

Corrosion Resistance

Grade 904L stainless steels have excellent resistance to warm seawater and chloride attack. The high resistance of grade 904L against stress corrosion cracking is due to the presence of high amounts of nickel in its composition. Moreover, the addition of copper to these grades develops resistance to sulphuric acid and other reducing agents in both aggressive and mild conditions.

 

The corrosion resistance of grade 904L is intermediate between super austenitic grades, with 6% molybdenum content, and standard 316L austenitic grades. Grade 904L is less resistant to nitric acid than grades 304L and 310L, which are free of molybdenum. This steel grade needs to be solution treated following cold working, to achieve maximum stress corrosion cracking resistance under critical environments.
