Carbon steel grades of steel are generally used in manufacturing low carbon steel bolts and nuts mentioned above in the above standards, gradesupto 6.8 are in non heat treated condition whereas bolts from 8.8 and above are heat treated to provide them with extra strength. Sometimes steel additions like Chromium and molubednum are added in the steel to provide the correct stregnth 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.
