Mar 11, 2016 · @Saftain- The minimum tensile strengths for these grades are all very similar. 8.8 and A325 have a minimum tensile of 830MPa (120ksi), and A193 B7 has a minimum tensile of 860MPa (125ksi). We have detailed summaries on our website for the two ASTM grades, we do not for the 8.8 grade.
ASTM A193 Scope - This specification is heavily utilized in petroleum and chemical construction applications and covers alloy steel and stainless steel bolting materials for high temperature or high-pressure service. This specification is intended for use in pressure vessels, valves, flanges, and fittings. Grades ASTM A193 B7 ALLOY STEEL ROUND BAR - Wingate Alloys ASTM A193 B7 ALLOY STEEL ROUND BAR. A193 B7 Alloy Steel Round Bar. Heat treated chromium-molybendum (AISI 4140) high-yield bolting steel for high pressure applications. A-193 B7 is considered as the most suitable for bolts used at temperature below 450°C with a minimum effect on its structural strength up to 1,000°F.
A194 gr. 2H vs A194 gr. 7 Nuts. Mostly ASTM A193 Grade B7 bolts are selected along with ASTM A194 Grade 2H nuts. However there is no ASTM or other standard where it recommends using A194 Gr. 2H nuts with this bolt. The reason that A194 grade 2H nuts are used more often with A193 grade B7 bolts is simply cost.
