ASME anchor bolt material grades
Thread Content
What are the common ASME material grades for the foundation bolts on towers? Could you please list a few? Thank you for your expertise: lol
High-strength fasteners: SA193 - B7, B16 (resistant to H2S stress corrosion); SA193 - B7M (austenitic stainless steel, low strength); SA193 - B8 c1.1 (304) (austenitic stainless steel, strain-hardened, medium strength); SA193 - B8 c1.2 (304); SA320 - L7 for low temperatures; high-strength austenitic steel fasteners for high temperatures: SA453 - 660
You are referring to the compression bolts on flanges, right? I would like to know the common grades of foundation bolts. Thank you
In China, 16Mn is used for towers with high requirements, while Q235A or Q235B can be used for those with lower requirements. Abroad, ASTM/A36 or ASTM A/307 are commonly used
