ASTM A193 B6 Stud bolt Manufacturer
ASTM A193 Grade B6 refers to a martensitic class of stainless steel, AISI 410. which is Intended to make the stud bolt used in general purposes.
ASTM A193 Grade B6 stud bolts are martensitic stainless steel fasteners designed for high-temperature and corrosion-resistant applications. These bolts are commonly used in petrochemical, power generation, and chemical processing industries due to their strength and resistance to oxidation.
12% Chromium Ferritic Steel. ASTM A193 Grade B6 is a material specification for 12% chromium- alloyed Ferritic steel
