What is Stainless Steel 904L Fasteners -

Amigo Impex is a renowned name in supplying and manufacturing of stainless steel 904 L Fasteners. We have been part of this industry for many years serving our clients with our superior quality products. We specialize in these fasteners in all standard sizes.

We supply a comprehensive range of 904L Stainless Steel Fasteners in different types, grades, and dimensional specifications. The inherent anti-corrosive properties allow 904L to be used in a wide variety of industrial applications. These fasteners are extremely resistant to all kinds of corrosion and this is what makes them highly popular in its category. These SS fasteners are made of high-grade steel and other materials. 904L Fasteners have more corrosion resistance than grades such as 304L and 316L which are free from molybdenum. For the maximum stress corrosion cracking resistance in critical environments, this kind of steel should be treated with a solution. This is particularly done after cold working the parts into fasteners.

These fasteners are known for giving good resistance to both organic and inorganic acids. The content of copper in this grade of fasteners gives excellent corrosion resistance in comparison to nickel stainless steels to all kinds of acid attacks. These fasteners give a high resistance to pitting in chloride solutions. And with that, they exhibit excellent resistance to both crevice and stress corrosion cracking. These fasteners are much better than austenitic stainless steels. This is because of the higher alloying of nickel and molybdenum. The high percentage of chromium content in these fasteners gives and maintains a passive film on the outer surface. This is the outer film which protects the material in many corrosive environments.

This is a category of fasteners on which cold forming can be performed easily. The combination of molybdenum and nitrogen implies the need for powerful processing equipment. Hot and heat forming is normally done after uniform heating. And annealing should be done before any hot forming. This is to retain maximum ductility and corrosion resistance property in the alloy. It is very important to the main elevated levels of temperate while the entire process. The heat treatment should be followed by cooling in water or air. These potent mechanical and chemical characteristics of these fasteners are the prime reasons for its high level of usage in paper & pulp and chemical processing plants.
