The stainless steel 440 Screw is composed of a unique chemical alloy to ensure its strength and durability. This alloy contains chromium, iron, carbon, manganese, silicon and molybdenum in varying amounts depending on the specific application for the screw. Chromium imparts excellent corrosion-resistant properties to stainless steel, while iron provides notable strength and durability. Meanwhile, carbon and manganese help enhance the hardenability of the steel, with silicon adding even more power and non-magnetic behaviours. Finally, molybdenum provides additional creep strength, allowing it to serve in temperatures up to 845° Celsius without becoming brittle or degrading. Together, these components create a highly dependable part used in many industries.

SS 440 Screws are an incredibly versatile fastening product, popular with DIYers and professional tradespeople. A low-cost hardenable material can be used in various applications where superior strength and durability are needed. The grade 440 material gives the 435 stainless screws excellent high-temperature stability and resistance to corrosive materials such as saltwater, acids, and more. These screws are designed for simplified insertion into wood or metal surfaces without pre-drilling. Thanks to their heat treatment and excellent magnetic attraction, these stainless steel screws provide a dependable hold to keep parts firmly connected.

FAQ's for Stainless Steel 440 Screw

The Harmonized System of Nomenclature (HSN) code for stainless steel 440 screw is 7318.

Welding stainless steel 440 screw requires using a TIG (inert tungsten gas) welding machine. This type of machine uses an inert gas such as argon to protect the metal from oxidation while it welds. The process also involves using a filler metal with similar characteristics to the base metal to create the strongest weld possible.

The stainless steel 440 screw is good quality and suitable for many applications due to its strength and durability. It can resist corrosion better than other types of screws, making it ideal for use in marine or coastal environments. It is also relatively easy to work with compared to other metals, making it popular among metalworkers and fabricators.
