ASTM A194 GR.8 Bolts uses are as varied as the sectors they support, led chiefly by the aerospace, railway, construction and automotive industries alongside petrochemical, nuclear, medical, Oil & Gas, Chemical, Pharmaceutical, Food & Beverage, Nuclear, Thermal Power plants, Paper and Pulp, marine and mining, etc.
ASTM A194 Grade 8 bolts, made from austenitic stainless steel, are less prone to galvanic corrosion than metals that are less noble. Nevertheless, when combined with metals that differ considerably, such as aluminum or carbon steel, galvanic corrosion may take place, particularly when an electrolyte like seawater is present.
