ASTM A193, Grade B7
Grade B7 is a heat-treated chromium-molybdenum alloy steel material. Intended for high temperature service.
Maximum Temperature 482°C / 900°F
Minimum Temperature -45C / -50°F

ASTM A193, Grade B7M
Grade B7M is a heat-treated chromium-molybdenum alloy steel. Minimum yield and tensile strength requirements are reduced compared to B7. Intended for high temperature corrosive environments.
Maximum Temperature 482°C / 900°F
Minimum Temperature -45°C / -50°F

ASTM A193, Grade B16
Grade B16 bolts are made from a chromium-molybdenum-vanadium alloy steel. Designed for use in high-temperature and high-pressure applications that require greater strength than B7.
Maximum Temperature 593°C / 1100°F
Minimum Temperature -45°C / -50°F

ASTM A320, Grade L7
Grade L7 has the same chemical and physical properties as B7. Additional ASTM specifications recommend a minimum Charpy impact value for ASTM A320 L7 Stud Bolts to be 20-ft-lbf @ -150F. Intended for low temperature applications.
Maximum Temperature 593°C / 1100°F
Minimum Temperature -45°C / -50°F

ASTM A320, Grade L7M
Similar to L7 studs except that the minimum yield and tensile strength requirements are reduced, intended for use in low temperature corrosive environments.
Maximum Temperature 593°C / 1100°F
Minimum Temperature -100°C / -150°F

ASTM A320, Grade L43
A320 Grade L43 is intended for low-temperature service down to -150° F and has a minimum Charpy impact value of 20-ft-lbf at this temperature. In addition L43 can be manufactured up to 4″ whereas L7 can be manufactured Up to 2 1/2″.
Maximum Temperature 593°C / 1100°F
Minimum Temperature -100°C / -150°F

ASTM A193, Grade B8
ASTM A193 Grade B8 specification covers requirements for 304/304L stainless steel bolting material with high tensile properties, for use in high temperature and high-pressure corrosive service and other special purpose applications. Subdivided into 3 property classes with different tensile strength; Class 1, Class 2 & Class 2B.
Maximum Temperature 815°C / 1500°F
