When a project needs bolts that can handle both high pressure and high heat, choosing the right grade of ASTM B7 or B7M is crucial. This quick guide breaks down the two grades by chemistry, strength, the tests they go through, and the jobs each one does best.
<a href="https://www.dalloyedfasteners.com/astm-a193-grade-b7m-bolts.html">ASTM A193 B7M</a> is a chromium-molybdenum steel that gets tossed into the mix whenever engineers are building oil rigs, refineries, ships, or even heavy-duty car parts.
So what is A193 B7M, anyway? Put simply, it is a rule book that covers bolts, rods, studs, anchor bolts, and any other externally threaded piece made from that chrome-moly steel and heat treated to boost strength. The final exam for B7M calls for a yield strength of at least 75,000 pounds per square inch and a hardness score around 99 HRB.
