...) ( Ref 18 ). Stainless steels can, however, fail by SCC that is initiated by sensitization formed during heating, for example when welding. Such a failure in a reformer tube occurred at the welded junction between the type 321 flange and HK-40 catalyst tube. The weld and HAZ were sensitized when joined...

.... In the same investigation, the hot cracking sensitivity of the heat-resistant alloy HK-40 was also examined. This alloy solidifies as primary austenite and terminates solidification with a eutectic-like Cr 7 C 3 carbide constituent. This is prototypical solidification behavior of a wide range of heat...

... of the gold deposit. Initially, wear resistance was increased by hardening the deposit to 150 to 250 HK. Later, wear resistance was increased by altering the crystal orientation of the gold deposit from the (100) plane to the slip plane, (111). Both of these results were achieved by the addition of controlled...
