Low Carbon Steel (Mild Steel): Typically contain 0.04% to 0.30% carbon content. This is one of the largest groups of Carbon Steel. It covers a great diversity of shapes; from Flat Sheet to Structural Beam. Depending on the desired properties needed, other elements are added or increased. For example: Drawing Quality (DQ) – The carbon level is kept low and Aluminium is added, and for Structural Steel the carbon level is higher and the manganese content is increased.

Medium Carbon Steel: Typically has a carbon range of 0.31% to 0.60%, and a manganese content ranging from .060% to 1.65%. This product is stronger than low carbon steel, and it is more difficult to form, weld and cut. Medium carbon steels are quite often hardened and tempered using heat treatment.

High Carbon Steel: Commonly known as “carbon tool steel” it typically has a carbon range between 0.61% and 1.50%. High carbon steel is very difficult to cut, bend and weld. Once heat treated it becomes extremely hard and brittle.

Carbon steel grades of steel are generally used in manufacturing low carbon steel bolts and nuts mentioned above in the above standards, grades up to 6.8 are in non heat treated condition where as bolts from 8.8 and above are heat treated to provide them with extra strength. Sometimes steel additions like Chromium and molybdenum are added in the steel to provide the correct strength required as per high tensile grades.

We manufacture and export the entire range of carbon steel bolting used in engineering and the contruction industry all over the world. These are also high tensile bolts and nuts and the popular standards like 8.8 and 10.9 grade are manufactured in our factory in India. We produce and export over 200 tons of high tensile fasteners to middle east and Europe. We also manufacture mild steel bolts and nuts, 4.6 grade bolts and nuts, 8.8 grade nut bolts, 10.9 grade bolts and nuts, carbon steel bolts nuts, nut bolt.
