Welding Cast Iron, an easy to follow guide

 · FerroNickel Rods are cheaper than pure Nickel and are ideal for welding Cast Iron to Steel. Pure Nickel will produce a softer, more malleable weld deposit. I would advoe using FerroNickel, unless the job specifically requires Pure Nickel. Mig Welding is, in my opinion, not a great way to weld Cast Iron. Whilst there are specialist Flux Cored Wires available, unless you have a repeating ...

Electroplating formulation and process for plating iron ...

 · The use of this activation/electroplating formulation and process allows the formation of relatively thick iron layers from about to about mils that have a microhardness greater than about 50 Rockwell C. Preferably, the microhardness is greater than about 55 Rockwell C; more preferably, greater than about 60 Rockwell C.

Cast Iron

Cast iron has excellent properties as a ring material, but is not that tough. The microscopic stress concentration caused by flaky graphite is likely to initiate cracking, and the flaky graphite microstructure is too weak to resist such cracking. To increase the strength, nodular graphite cast iron (JIS FCD), which includes spherical graphite, has become more widely used. It is also called ...

Martensite Microstructure

Cast iron rings are heatresistant even when exposed to high temperatures. The hard martensite or pearlite microstructure does not soften at high temperatures. The high quantity of alloying elements (especially a Si content of around 3%) gives excellent resistance against tempering. Only casting can shape such high alloy compositions.

Prevention of ValveSeat Erosion

formation of this deposit have been questioned. One experimenter offers the opinion that the accumulation may be, not an oxide, but an iron carbide, starting in the form of particles of carbon deposited on the seat, which particles pick up iron from the castiron seat and then, in themselves, become extremely hard protrusions. These protrusions aid greatly in accelerating the seat erosion, as ...
