Fasteners, which include more chromium and nickel than the 316L grade. Our highly equipped
infrastructure facility produces things that satisfy international quality and reliability
standards. We provide some of the most dependable items in the business, as well as exceptional
service.
What is a Stainless Steel 904L Fastener?
904L stainless steel is an austenitic, non-stabilized grade. The letter L in the fastener's name
indicates that it has lower carbon content in its chemical makeup. 904L stainless steel fasteners
are non-stabilized austenitic stainless steel. In these fasteners, the carbon content is around
0.02 percent, giving resistance against intergranular corrosion.

Features of SS 904L Fasteners:
- 1) A little amount of copper is found in these fasteners’ compositions. As a result, it can survive
acidic environments such as sulfuric acid. Because these fasteners include high levels of nickel and
molybdenum, they are very resistant to corrosion-related pitting and cracking.
- 2) These Stainless Steel 904L Fasteners have a maximum carbon content of 0.02 percent. Indeed, the
low carbon concentration of these fasteners renders them immune to welding sensitization, avoiding
intergranular corrosion.
- 3) SS 904L is an Austenitic Steel with a lower carbon concentration. Grade 904L has exceptional
ability to form and weld along with high strength.
- 4) Moreover, under any type of situation, grade 904L remains non-magnetic. SS 904L resists pitting,
crevice corrosion, and stress corrosion cracking in chloride solutions.
- 5) Because of its greater nickel and molybdenum concentration, SS 904L Fasteners are noted for their
superior performance when compared to other alloys.
Applications of SS 904L Fasteners:
These features enable it to be used in a variety of sectors, including seawater cooling equipment,
condenser tubes, heat exchangers, acid chemical processes, and more. UNS N08904 Fasteners are utilized
in a variety of sectors including automotive, marine, seawater, aerospace, oil and gas, pharmaceutical,
food processing, chemical, and general engineering.
