Table of Content
The primary reason that has businesses choose using alloy steel over carbon steel grades is that their properties are noticeably higher. Unlike carbon steels, which provide the user with minimum to no corrosion resistance properties, Alloy Steel Fasteners Manufacturers In China recommend using steels belonging to this category, simply because their properties are better. Though in comparison the cost of using Alloy Steel Bolts for these applications makes the overall cost a little higher, the improvement of the properties makes it worth it.
Along with being tough, the Alloy Steel Stud Bolts generally display good behaviour when exposed to both low as well as high temperature settings. They have a higher tolerance to oxidation. Some grades of Alloy Steel Nuts, depending on their chemistry, have very high tensile strength, some of which are even better than conventional stainless steel grades. Not only is the Alloy Steel Washers hard, but they also have better durability and are able to take high pressure loads, without the fear of failure.
Unlike carbon steels that are hard and brittle, these fasteners have some form of ductility, which is important, especially if they are under duress. A small amount of ductility enables the Alloy Steel Screws to expand to such a degree that it is able to cater to the application, without breaking.
