| NbC introduction | Niobium carbide is a frequent intentional product in microalloyed steels due to its
extremely low solubility product in austenite, the lowest of all the refractory metal carbides. This means that micrometre-sized precipitates of NbC are virtually insoluble in steels at all processing temperatures and their location at grain boundaries helps prevent excessive grain growth in these steels. This is of enormous benefit, and the cornerstone of microalloyed steels, because it is their uniform, very fine grain size that ensures both toughness and strength. The only commonly occurring compound with a lower solubility and hence, greater potential for restricting the grain growth of steels is titanium nitride. |

Application: |
a) Niobium carbide is a frequent intentional product in microalloyed steels due to its extremely low solubility product in austenite, the lowest of all the refractory metal carbides b) Niobium carbide has an extremely low solubility product in austenite. When niobium carbide is added by micrometre-sized precipitates, it is virtually insoluble in steels at all temperatures. Niobium carbide's location at ground boundaries prevents excessive grain growth. c) Niobium has many medical research applications. It is also alloyed to produce arc-welding rods and in corrosion-resistant steel. Niobium carbide is an extremely hard, corrosion resistant refractory ceramic. It is a brown gray metallic power with purple lustre. |

FAQ
1.What size do you need? Since we have 60-325mesh,
a.0.8um: normally used as additives in carbide, cutting tools,etc. (additive amount:0.1%~2%)
b.60-325mesh: mixed with other materials normally used in spraying coating, which have strict
requirement in particle size and its mixture evenness.
c.3~5um:normally used in alloy products.
2.our test methods are as follows:
a.FSSS Fisher Sub-sieve sizer b.Laser c.SEM d.Seizing e.apparent density of powders
3.Delievery time:about 7 days for carbide powder.
