What is A325 bolts ?

Elements such as carbon, manganese, phosphorus, sulfur as well as silicon along with some other elements are present in the chemical composition of these A325 bolts. For the type 1 bolts, they could be made up of medium carbon steel or born steel or even medium carbon alloy steel. For the type 2, they could either be made up of martensitic or low carbon steel. The type 3 could be of the weathering steel.

The type 3 are at an advantage here because they possess a property where they can heal even if they are damaged. This is done by producing an oxide layer to prevent the further oxidation that could likely occur. These bolts are useful for the purpose of having a flat surface for the utility.

ASTM A325 is the standard specification for heavy hex structural bolts in heat-treated steel with a minimum tensile strength of 120/105 ksi Exporter.

Sumit Impex is widely known for producing excellent quality A325 bolts. They consider all the rules, regulations as well as the standards and guidelines that are used to produce a product which is of a high quality. These A325 bolts are used for steel to steel connections or structural steel connections.

These A325 bolts have a structure which is often referred to as heavy hex geometry which distributes the load effectively. These A325 bolts are also used in a large number of industrial applications because of the properties and the characteristics that they have.
