OriginDomestic and approved mills, inspected and certified in Hillsboro
Sourced alloy, certified in HillsboroAmeritube does not manufacture Alloy 600 in Texas. It is supplied from qualified domestic and international mills, then received, inspected, tested, and released under our ISO 9001:2015 system in Hillsboro, Texas, with a full mill test report.
What Alloy 600 is
Alloy 600 is a nickel-chromium-iron solid-solution alloy. The high nickel content gives it immunity to chloride stress corrosion cracking and excellent resistance to caustic and to high-purity water. The chromium provides oxidation resistance at temperatures well beyond the stainless steels. It is non-magnetic, readily welded, and keeps its strength and ductility from cryogenic temperatures to over 2000 degrees F.
Standards we supply to
- ASTM B163 / ASME SB-163, condenser and heat exchanger tube
- ASTM B167 / ASME SB-167, seamless pipe and tube
- ASTM B516 and B517 welded on request

Where it is used
- Heat treating furnace muffles, retorts, and radiant tubes.
- Nuclear steam generator and reactor internals (legacy plants; newer units often specify Alloy 690).
- Caustic evaporators and chlor-alkali equipment.
- Chemical process exchangers in chlorides, organic acids, and high-temperature halogens.
- Aircraft and gas turbine engine components.
What to put in your Alloy 600 RFQ
OD, wall, length, quantity, ASTM B163 (heat exchanger) or B167 (pipe and tube), heat treatment, design temperature, and any nuclear, ASME Section III, or customer specification. Ameritube maintains documented procedures for nuclear heat exchanger tube.
