Technical FAQs — ASTM A193 Grade B8 Class 1 MTC Certificate
What is the significance of "Class 1" in ASTM A193 Grade B8?
Class 1 indicates that the fasteners have been carbide solution treated (annealed) but not strain-hardened. This provides an excellent balance of ductility and corrosion resistance with a maximum hardness of 96 HRB, distinguishing it from Class 2 fasteners, which are intentionally strain-hardened to achieve higher tensile and yield strength.
What environments are Grade B8 Class 1 bolts best suited for?
Manufactured from AISI 304 stainless steel, Grade B8 Class 1 bolts are the industry standard for general high-temperature service and highly corrosive environments. They are widely specified in chemical processing, petrochemical refining, food processing, and power generation due to their reliable oxidation resistance and structural stability.
Are the materials verified to be free from radioactive contamination?
Yes, the MTC document strictly states that the material has been verified as free from radioactive contamination and has undergone a 100% visual inspection to ensure it is completely free from manufacturing defects before dispatch.
