ASTM A193 B8 Class 2 Bolts

ASTM A193 is a specification that covers bolting material, for instance, the A193 B8 Class 2 Heavy Hex Bolts for both alloy steel as well as stainless steel. Typically the specified ASTM A193 B8 Class 2 Fasteners have been designed for use in high temperature or/and high pressure applications.

 Hence, the A193 B8 Class 2 Material is well suited to be used for pressure vessels, valves, flanges, fittings and for other special-purpose applications. While there are different grades covered under this specification, these grades are divided into two sub-categories i.e. class 1 and class 2. ASTM A193 B8 Cl1 indicates that the fastener has been carbide solution treated, whereas ASTM A193 Grade B8 Class 2 Bolts indicates that the fasteners are not only carbide solution treated but also strain hardened.

In terms of grades, B8 would mean the alloy belongs to austenitic grade 304. To exemplify, ASTM A193 B8 Class 2 Bolts are bolts made from grade 304 which are furnished in a carbide solution treated and strain hardened condition. Since the A193 B8 Cl2 Strain Hardened Studs fall under the austenitic classes of stainless steel, the specification guides the manufacturer with the elements in the chemistry. Hence, the ASME SA193 Grade B8 Class 2 Bolts needs to conform to the chemistry without the addition of an unknown element.

Moreover, the tensile property and hardness property requirements of the B8 CL2 Torque & Yield Strength have been discussed in this specification. Click here to download the astm a193 b8 class 2 torque chart.

Notes:

• Bolting torque to develop 50% Bolt Yield Stress at Nut Factor, K=0.16
• This Table is applicable to Never-Seize paste and Fel-Pro lubricant, K=0.16.
• The above Table is applicable only for ASTM A320 Grade B8, Class 2 and A193 Grade B8, Class 2 Stud Bolts. These are 304 SS material.
• The torque values are approved for spiral wound graphite and PTFE filled gaskets, graphite sheet gaskets GHE and GHR types, ring joint, double jacketed and Camprofile gaskets.
• The Final Torque Value accounts for 10% bolt relaxation.
• The yield strength for strain-hardened bolts varies with diameter. Torque values for bolts greater than 1½ in. diameter are based on 30 ksi yield strength.
