Ganpat Industrial Corporation punches and heat treats ASTM A194 Grade 2H Washers at our Mumbai works. The blanks start life as medium carbon steel, quenched and tempered exactly the way A194 Grade 2H nut stock is treated. That gives you a bearing face hard enough to sit under a torqued heavy hex nut without biting into the flange. Refinery, boiler and pipeline buyers order these washers alongside A193 B7 stud bolts, so the whole bolted joint arrives on one packing list with one heat trail. Sizes run M6 through M56 and 1/4″ through 4″. Non catalogue bores get cut from your drawing. Every carton leaves with an EN 10204 3.1 mill certificate. We ship from Mumbai to Chennai, Vadodara and Vizag, and export to Dubai, Dammam, Doha, Muscat, Lagos and Rotterdam.
