Although the alloy was designed for use in sulfuric acid related industries; our ASTM A193 Grade B7 Alloy Steel Stud finds wide usage throughout the chemical processing industry. We manufacture these ASTM A193 Grade B7 Metal Stud which is manufactured using finest grade raw material available to ensure international quality. The combination of strength, corrosive resistance and an ability to withstand the damaging effects of pitting and crevice corrosion in our ASTM A193 Grade B7 Stud Bolts, leads to a life expectancy far in excess of that achieved by standard steels. The main weakness inherent in these ASTM A193 Grade B7 Alloy Steel Stud Bolts, for example, is the fact that it boasts fairly low strength and thus relatively low resistance to stress corrosion cracking.
