Raw Material: Carbon Steel

Carbon steel is a steel with carbon content up to 2.1% by weight.

As the carbon percentage content rises, steel has the ability to become harder and stronger through heat treating; however, it becomes less ductile. In carbon steels, the higher carbon content lowers the melting point.

The purpose of heat treating carbon steel is to change the mechanical properties of steel, usually ductility, hardness, yield strength, or impact resistance.

Case hardening processes harden only the exterior of the steel part, creating a hard, wear resistant skin (the "case") but preserving a tough and ductile interior.

Concrete screws, also known as masonry screws, are a type of fastener that holds one or more objects together or secures an object in place. They are commonly used to fasten certain materials, such as metal or wood, to concrete or masonry. Concrete screws are commonly made of steel, galvanized steel, or carbon steel, and they can have a finish such as zinc or blue stalgard. Often blue in color, they are sometimes referred to as blue screws.
