ASTM A193 B6X Bolt
ASTM Standard Bolt
ASTM A193 B6X Hex Head Bolt, ASME SA193 Grade B6X U Bolt, UNS C41000 Flange Head Bolt, B6X Grade Stud Bolt, AISI Grade B6X Allen Bolt.
Alloy 410 SS is also referred to as grade B6x or by its UNS number, S41000. Essentially, martensitic steel, 410, is used to make ASTM A193 Grade B6x Stud bolts. The ASTM A193 B6x Threaded Rod, which exhibits alloy 410’s high tensile strength and hardness, is this material’s primary industrial application. The ASTM A193 Grade B6x Hex Bolt is made of an alloy with a 12% chromium content and trace amounts of phosphorus, manganese, silicon, sulphur, carbon, and nickel.
The Sa 193 Gr B6x fasteners’ corrosion resistance feature is sufficient due to the high proportion of chromium in this stainless steel composition, making them suitable for general-purpose applications. Although the alloy’s modest corrosion resistance capabilities could be sufficient for these applications, subjecting the ASTM A193 Grade B6x Bolts through procedures including tempering, hardening, and finishing increases the alloy’s corrosion resistance.
About ASTM A193 B6X Bolt
The resistivity rate to corrosion of the B6x Alloy is weaker than that of typical austenitic stainless steels. The A193 B6x Bolt can withstand greater temperatures because chromium serves as the principal alloying element in this composition, with the other elements acting as secondary alloying components. Additionally, the B6x Bolt performs well despite being subjected to mild or diluted acidic solutions, including acetic acid, sulfuric acid, nitric acid, and naptha.
