ASTM A193 B16 ALLOY STEEL ROUND BAR

A193 B16 Alloy Steel Round Bar

The ASME A193 designation covers fasteners intended for use in pressure vessels, valves, flanges, and fittings. The addition of vanadium makes this heat treated chromoly steel (AISI 4140) particularly resilient in high temperature environments. A-193 B16 is considered as the most suitable for bolts used at temperature below 450°C with a minimum effect on its structural strength up to 1,100°F.
