Can you weld Ni-Hard?
Martensitic cast iron (Ni-Hard types) and the various white irons are generally considered too crack-sensitive or brittle to be welded satisfactorily.
Is Ni-Hard magnetic?
Ni-Resist D-6 – Is non-magnetic with good mechanical properties.
Where is Ni-Hard iron used?
Ni-Hard castings are typically used in power generation, brick, asphalt, cement, concrete, rock, sand and gravel industries. Typical castings are mill or mixer liners, mixer tips and slurry pumps.
What is the chemical composition of cast iron?
Cast iron is one of the oldest ferrous metals in commercial use. It is primarily composed of iron (Fe), carbon (C) and silicon (Si), but may also contain traces of sulfur (S), manganese (Mn) and phosphorus (P). It has a relatively high carbon content of 2% to 5%.
What is NI hard material?
Ni-Hard is the generic name for a family of white cast irons alloyed with nickel and chromium to give high hardness and outstanding resistance to abrasion.
What are the properties of white cast iron?
White cast iron has a light appearance due to the absence of graphite. It has a high compressive strength and retains good hardness and strength at higher temperatures. The presence of different carbides, depending on the alloy content, makes white cast irons extremely hard and abrasion resistant but very brittle.
Do magnets stick to nickel?
Note that the U.S. five cent coin called a “Nickel” is made of 75% copper and 25% Nickel (Ni). Even though it contains Nickel (Ni), a ferromagnetic material, they aren’t visibly attracted to magnets. In fact, they don’t interact with magnets like many other non-magnetic materials.
What is NI resist material?
Ni-Resist or Ni Resist alloy grades are austenitic gray cast iron casting grades that provide good hardness, dampening, and some corrosion resistance. These grades are very brittle and cannot be welded.
What is composition of steel?
Steel is an alloy of iron and carbon. Stainless steels are steels containing at least 10.5% chromium, less than 1.2% carbon and other alloying elements.
What are types of cast iron and their characteristics composition and application?
It is the combination of high carbon content, and the presence of silicon, that gives cast iron its excellent castability. Various types of cast irons are produced using different heat treatment and processing techniques, including gray iron, white iron, malleable iron, ductile iron, and compacted graphite iron.
