Stainless steel hex bolts or screws are offered in A4-70, A4-80, B8, B8M Class 1 and class 2, and in SS316S31 grades. We also offer these grades in 316 and 316L grade. The difference between 316 and 316L is simply the limit of carbon content to 0.03% maximum in 316L grade, whereas in 316 grade it is limited to 0.08%.
Stainless steel bolts provide a strong and a longer life where specific requirement of rust prevention is predominant. Predominantly stainless steel bolts are used in areas where there is a high risk of corrosion, this can be in TSE networks, affluent treatment plants, water pipe lines, pumping stations or in mega reservoirs. Stainless steel bolts provide high resistance to corrosion and normal wear and tear over the years.
Stainless steel bolts are generally available in bright self finish. Stainless steel bolts are polished or ground after forging and other activities to provide them with a bright finish. Sometimes customers require stainless steel bolts to be Xylan coated to provide an added layer on top of the surface bright finish.
Stainless steel bolts are used in underwater projects where there is direct contact with sea water, in drainage systems, affluent treatment plants, TSE networks, Pumping stations, desalination plants and various other sectors as.
We manufacture stainless steel Bolts in bigger diameters from M-20 to M-64 in diameter in class 316 namely, A4-70, A4-80, B8, B8M Class 1 and class 2. Finished material stocks are readily available and we are manufacturing bolts diameter from M-20 to M-64 diameter, Manufacturing process of stainless steel bolts is very similar to carbon steel or high tensile bolts as only heat treatment process is replaced by carbide solution treatment
