These grades offer better erosion or wear resistance because of the high hardness values that can be obtained through heat treatment. They do provide some corrosion resistance; however are not as resistant as the austenitic grades.
|Representative Alloys||CA15, CA6NM.|
|Applications||For good wear & corrosion|
|Limitations||CA15 is prone to cracking in heavy sections; special procedures improve stress corrosion cracking resistance|
|Typical Uses||Aerospace, gas turbines, marine, petro-chemical, pulp and paper, food processing|
|Machinability||Fair to good, based on grade & conditions|
|Weldability||Requires post-weld stress relief|
|Corrosion Resistance||Good in mildly corrosive environments; good erosion resistance, some grades have very good resistance to cavitations|
