Our products are quality tested and could be used with international standards. The ASTM A193 Grade B7 Threaded Rod is stronger because it is heat treated during the process. The ASTM A193 Grade B7 Studs are quenched and tempered through the heat treatment. The Grade B7 is a chromium molybdenum stainless steel alloy that can withstand high amounts of corrosion. Therefore the ASTM A193 Gr B7 Stud Bolt is used in high corrosive environments such as the marine applications and seawater applications along with the ASTM A193 Grade B7 Nuts. The ASTM A193 Grade B7 Material could also be hot-dip galvanized or zinc plated among other coating options. This allows the ASTM A193 Grade B7 Washers to be even further corrosion resistant. The ASTM-a193 Gr B7 Hex Bolt is used in high strength applications with high corrosion resistance requirements. Our ASTM A193 Grade B7 Cap Screws are forged so that they remain in shape and can withstand high tension just like the Grade B7 Hex Nut produced by us. The coating operation can increase corrosion resistance on these products but it reduces the temperature tolerance of them. You can contact us for further details.
