... (450 to 750 °F). This embrittlement phenomenon was considered the likely cause of the failures. In-service cracking occurred to a large piece of mining equipment. The vehicle was fabricated from ASTM A 572 Grade 50 High Strength Low Alloy (HSLA) steel, ranging in thickness from 38 to 152 mm. Fatigue...

.... Cracking is evident at toes of both fillet welds, as indicated by arrows. The cross member was specified to be fabricated from SAE 950X, a high-strength low-alloy steel, and to include a fillet-welded diaphragm, as detailed in Fig. 5 . Welding was performed with the gas metal arc process using 1.1...

Formation of these graphite bands probably expedited the creep failure of the tube. Future failures may be avoided by using low-alloy steels with...
