Stainless Steel 904L Fasteners

Metco Overseas is one of the known manufacturers, Suppliers and exporters of Stainless Steel 904L Fasteners, which are highly acclaimed for dimensional accuracies and long service life. Today, every industry, every sector is developing at a rocket speed and the demand for better machines, which could last longer than ever before, is also on a high demand. 

904L is an austenitic alloy and a grade of highly alloyed stainless steel. The stainless steel 904L fasteners’ better resistance to SCC, or stress related corrosion cracking, is one of the benefits of adopting the alloy. The presence of nickel in ss 904l screws is what confers the resistance to SCC. In addition to improving the resistance properties of the 904L Stainless Steel Fasteners, nickel also stabilise austenite.

The alloy also has a large amount of copper in addition to nickel. Copper boosts the alloy’s resistance to sulfuric acid as well as making UNS S08904 threaded rod resistant to saltwater and brine.

 The 904l stainless steel bolts provide resistance to highly corrosive reducing agents in both mild and demanding situations. Excellent toughness, non-magnetic behaviour, formability, and weldability are other qualities of 904L stainless steel bolts.

Like many austenitic stainless steels 904L Fasteners Bolts and Nuts have excellent oxidation resistance. However, it is not recommended to utilise ss 904l fasteners at such temperatures due to a structural collapse beyond a temperature of 400°C.

Our SS 904L Fasteners (WNR 1.4539) are utilised in a wide range of applications, including those for heat exchangers, structural pipes, plumbing, heating, oil and gas pipelines, power plants, and water supply systems.
