    1. What is the definition of alloy steel bolts?


    Alloy steel bolts are made from a high strength steel alloy and are further heat treated. Alloy steel bolts are typically not plated, resulting in a dull black finish. Alloy steel bolts are extremely strong but very brittle.

    Our common alloy steel material grade is ASTM A193 B7, B7M, ASTM A320 L7, ASTM A325, for bolts; ASTM A194 2H, 2HM for nuts; ASTM F436 for gaskets.
