High Carbon Steel Hex Bolt & CS Fasteners manufacturer in India

The definition of Carbon steel is any steel that contains carbon content up to 2.1% of its weight. As the carbon content increases, the Carbon Steel Bolt tends to become much harder & would have increased strength - after being processed by heat treatment. However, the steel becomes less ductile. Regardless of the heat treatment performed on the carbon steel alloys, a higher content of carbon in the material reduces weldability in Carbon Steel Fasteners, while also effectively lowering the Bolts melting point. Most Carbon Steel Stud Bolts are usually relatively soft. They also exhibit low strength. However, low carbon steel is highly pliable. High ductility is a property that makes the material excellent for machining & welding. The absence of different elements - used as alloyants, as opposed to other classes of steels is what contributes to the nuts and bolts dubbed as low-cost Bolts. Carbon Steel Nuts and Bolts grades fall into three different categories based on the content of carbon that is Low, medium, and high carbon steel.

Low-carbon steel fasteners vs Medium carbon steel

Low Carbon Steel Hex Bolt are the most widely used category amongst all the carbon steel groups. The alloy of low carbon steel threaded bolts usually has a carbon content of less than 0.25% of its total weight. Since this type of carbon steel Bolts cannot be hardened by heat treatment to promote the formation of martensite, the alloy is cold worked.

In this particular low carbon steel category is another type of steel, referred to as High-strength low-alloy steels, or as shortened as HSLA. Although HSLA screws belong to a class of low-carbon steels, one can note that the alloy of HSLA Bolts contain other elements, for instance, copper, nickel, vanadium, and molybdenum. The combination of the said elements sums up to 10% of the weight of steel content. As the name suggests, HSLA bolts have higher strengths, achieved through heat treatment. These washers remain ductile, making them easily formable and machinable while exhibiting more corrosion resistance than regular low-carbon steels.

Medium Carbon Steel Bolts, Anchor Bolts, Threaded Rod, Studs, Nuts & Self Drilling Screws have a carbon content between 0.25 - 0.60%, with the content of manganese between 0.60 - 1.65% of its weight. The mechanical properties of these stud bolts improve via heat treatment. The heat treatment process involves austenitizing, followed by quenching and tempering. Undergoing these processes is what gives it a martensitic microstructure. Hardened medium-carbon steel Bolts have greater strength in comparison to low-carbon steels. Though, this is a property that comes at the expense of toughness as well as the loss of pliancy.

High Carbon Steel Bolts have a carbon content that ranges between 0.60 - 1.25%. The alloy of high carbon steels has a manganese content in the range of 0.30 - 0.90%. Amongst all the three grades, High carbon steel threaded rods have the highest hardness and toughness properties while exhibiting the lowest ductility. The exhibition of high wear resistance property stems from the fact that these screws are almost always processed by hardening and tempering.

Two sub-categories of high carbon steels that are Tool and die steels contain additional alloying elements such as chromium, molybdenum, vanadium, and tungsten. Adding these minerals results, in a remarkably hard, robust, and wear-resistant hex bolt, due to the formation of - carbide compounds; for example, tungsten carbide (WC).
