At Greystone Alloys, our biggest goal is gaining our suppliers' utmost trust by dealing as fairly as possible and making each transaction as logistically seamless as possible. Our Sure Step™ Process, outlined below, creates transparency with each transaction. This insures that you, our supplier, understand exactly what you are getting and what to expect from dealing with us.Alloy recycling and processing services. Capabilities include scrap metal, tungsten carbide and plastic scrap recycling services.
Capabilities / Services
Scrap metal recycling services. Capabilities include molybdenum scrap, monel scrap, tantalum scrap, tool steel scrap and zirconium scrap recycling services. Also provide Inconel 625, Inconel 718, Hastelloy, Haynes scrap and spray powders recycling services.
Greystone alloys specializes in processing and recycling of high temperature alloys such inconel, hastelloys, stellites, and other nickel/cobalt alloys. We purchase quantities from our industrial clients and other scrap recyclers, then process and grade materials to specifications for our specialty buyers and foundries. Scrap metal recycling in Houston has many different sources such as oil/gas job shops, petrochemical plants, power generation and aerospace.All these industries require alloys that can survive under high stress conditions; including high temperature and corrosive and erosive environments. Alloys received containing multiple alloys will be purchased for Nickel or Cobalt containment, whichever is greater. All metals received are individually graded with our XLF Niton analyzer.
Thus, making us one of the world's largest tungsten carbide processors. The list below are just some of the forms that we buy:
- Inserts
- Endmills
- Boring bars
- CB Drills
- Pumping rods
- Shearing knives
- Medical saw blades
- Radiation shields
Mallory and Hevimet are two tungsten alloys that are usually mistaken to be WC, but these alloys are not bonded by carbon, but alloyed with Ni or Ni and Copper (Cu). Tungsten in alloys such as Ni Alloys, Ni Co Alloys, and Co Alloys give them greater integrity. Tungsten’s extremely high melting temperature (3400 C) and density(atomic number 74) adds to the resistance of thermal expansion. This is extremely important in aerospace alloys, where retaining shape in extreme temperature and stress are necessary for performance.
