Rudrani Overseas is one of the well-known suppliers of Alloy Steel B7 Fasteners, which offers stabilized grades for heavy section welding and high temperature applications. Molybdenum additions in Alloy Steel ASTM A193 Grade B7 Nuts are also well known to reduce the behavior of the steel in nitric acid solutions. While being highly resistant to halides and many other concentrated acids for Alloy Steel ASTM A193 Grade B7 Bolts, resistance to nitric acid remains its key feature. The high chromium and nickel content in Alloy Steel ASTM A193 Grade B7 Screws give the steel excellent oxidation resistance as well as high strength at high temperature.
The sharp control of carbon, silicon and phosphorus contents in Alloy Steel ASTM A193 Grade B7 Washers makes it possible to produce a more stable austenite microstructure, free of intermetallic or carbide precipitations. Alloy Steel ASTM A193 Grade B7 Hex Head Nuts has very good resistance to intergranular corrosion, pitting and stress corrosion cracking due to its high chromium and nickel contents.
Alloy Steel ASTM A193 Grade B7 Hex Head Bolts offers an extensively inured to the effect of sulfurous gases, especially above 900 Degree C. Thermal spray coatings in Alloy Steel ASTM A193 Grade B7 Hex Head Screws have been demonstrated to be effective in protecting the steel from wear at elevated temperatures.
