Stainless Steel B8T Fasteners are corrosion-resistant, austenitic stainless steels. They exhibit good mechanical properties, and corrosion resistance in high-temperature environments. ASTM A193 Grade B8T bolts are based on austenitic stainless steel alloy 321 material. The fastener's chemical composition, mechanical properties, and recommended heat treatment are described in the standard.


Stainless Steel ASTM A193 B8T Fasteners exhibit enhanced overall corrosion resistance. The alloy steel is resistant to pitting and crevice corrosion in chloride-rich environments. B8T Fasteners are nickel-iron-chromium-molybdenum steel that provides excellent strength up to 1200°C. As an automotive exhaust grade, they have excellent corrosion resistance.


Type 304 stainless steel hex bolts must be carbide-treated and stamped according to ASTM A325 specification. Carbide solution annealing, or "solution annealing", is a process that uses a high temperature to dissolve chromium carbides and restore the bolts' optimal corrosion resistance. Finished fasteners must be stamped with the "B8" designation and unique manufacturer's identifier.


Socket Set Screws, Anchor Screws, and Blind Rivets are all types of Stainless Steel B8T Fasteners. You can use these types of screws and bolts in various applications. They're also useful in construction. But they can't be used in a concrete job. Socket Set Screws are the most popular fasteners in masonry projects. But these aren't the only fasteners made of this material.
