| These
alloys are chosen for metal-to-metal wear resistance and for less severe
abrasion resistant applications. Heat resistant is generally up to
1100ºF(595ºC). Alloy content ranges from 10 to 20% and carbon
levels are generally less than 1%. |

Hardness is a good indicator of wear resistance. | |||||||||||||||||||||
|
High hardness types (over 55 Rc) are considered non-machineable and have a limited deposit thickness. They will cross-check. | |||||||||||||||||||||
|
High
chromium (10 to 15%) martensitic alloys provide excellent metal-to-metal
wear and thermal shock resistance, and moderate corrosion
resistance. In addition, deposits are generally machineable and overlays
can be applied crack-free with proper welding procedures. |
