ASTM A193 B7 v.s. A320 L7 Stud Bolts - wermac

ASTM A193 B7 vs A320 L7 Stud Bolts. ASTM A193 B7 is a Bolting specification for medium-high temperature applications. It is a heat treated Chromium Molybdenum steel and is considered for applications up to 450° Celsius (840° Fahrenheit). ASTM A320 L7 has the same chemical and physical properties as B7, with additional Charpy V Notch tests ASTM A453 Grade 660 Bolts A453 Grade 660 Class A/B/C/D ASTM A453 Covers Specification for High temperature Bolting with expansion co-efficient comparable to Austenitic Stainless Steel. One of the commonly used is grade 660 Bolts. We produce Stud Bolts, Hex Bolts,Expansion bolts,threaded rods etc as per A453 Grade 660 in Class A/B/C/D, intended for Special Engineering Applications.

ASTM A638 A286 Grade 660B / 660D - West Yorkshire Steel

This grade is suitable for applications requiring good corrosion resistance and high strength in temperatures up to 700°C. It can be used at higher temperauteres for lower stress applications.
