Nitride

In chemistry, a nitride is a compound of nitrogen where nitrogen has a formal oxidation state of −3. Nitrides are a large class of compounds with a wide range of properties and applications. The nitride ion, N, is never encountered in solution because it is so basic that it would be protonated. Its ionic radius is estimated to be 140 pm. Related to but distinct from nitride is pernitride, N2.en.wikipedia.org it, but this will probably create more problems than it is worth; nitriding would reduce the corrosion resistance.sp.info What is the hardness of 304 stainless steel?Type 304 stainless steel is a T 300 Series Grade 304 is the standard "18/8" stainless that you will probably see in Hardness, Rockwell B: 82: Tensile.Reference: www.discountstainlesssteel.com/stainless-steel/5244.htmlSee all results for this questionsp.info What are the properties of 304 stainless steel?Properties.
