What is Stainless Steel 317/317L Fasteners -

Amigo Impex is one of the leading supplier and manufacturer of stainless steel 317 & 317l Fasteners. We offer superior quality products to our diverse group of clients. These fasteners have excellent resistance to all kinds of corrosion. The oxidation resistance it portrays is due to the amount of chromium content. The welding and annealing is necessary in applications when stress loads are excessive. These fasteners offer excellent durability. The tensile strength of these fasteners is high at elevated temperatures. The content of molybdenum in the fasteners gives it similar properties to nickel. These fasteners are made from austenitic steel and these have low carbon content as compared to its counterparts.

The addition of molybdenum, nickel, and chromium makes it more resistive to pitting corrosion. These are extremely resistant to acid attacks by sulfuric, acetic, formic, citric and other acids. Due to its low carbon content, these fasteners are resistant to sensitization. These are known for offering higher creep, high tensile strength, and stress to rupture even at elevated temperatures. The presence of chromium gives a shiny outer finish to these fasteners and this is what makes these look appealing.

These are suitable for most welding and forming applications. That is why it is quite popular. This alloy works smoothly at low speeds and constant feeds that show its durability. These fasteners are known for representing a lower rate of scaling in varied atmospheric conditions. When it is in annealed condition then these sheets are non-magnetic. These can become slightly magnetic after welding.

Some of the industries that use this product for their applications are paper and pulp handling, several chemicals, and petrochemical applications, in food processing equipment, textile equipment and in condensers in fossil and nuclear-fueled power generation stations. These are widely and commonly used to handle acid dyestuffs and acetylating. Apart from that industries use these in nitrating mixtures, pulp liquor, bleaching solutions, sulfur. In addition to that, it also finds its utilization in handling severe coal and oil, and many chemical compounds. These are also used in manufacturing heat exchangers, in offshore drilling operations. Chemical and pharmaceutical equipment often see uses of it. Due to its corrosion characteristics, these are used in marine applications.
