AMETEK Specialty Metal Products uses a wrought powder metallurgical process to ensure the highest purity finished products. Our main strengths lie in the processing of Nickel, Iron and Cobalt containing alloys amongst other available materials. The processing of these materials begins with the consolidation of powder through a roll compaction process and followed by a controlled atmosphere sintering. Further reduction of the material is performed solely under cold working temperatures to reduce the introduction of non-metallics and annealing is performed under controlled atmospheres. AMETEK Strip Products are produced in ranges between .002” (0.05mm) and .080” (2.03mm) thicknesses in a full range of tempers and widths to 22” (558.8mm) while maintaining special capabilities to produce materials outside of these ranges for special applications. This process lends itself to the production of small but easily reproducible lots of highly specialized alloys

Alloy 800, 800H, and 800HT are nickel-iron-chromium alloys with good strength and excellent resistance to oxidation and carburization in high-temperature exposure. These nickel steel alloys are identical except for the higher level of carbon in alloy 800H/HT and the addition of up to 1.20 percent aluminium and titanium in alloy 800HT. Alloy 800 was the first of these alloys and it was slightly modified into Alloy 800H. This modification was to control carbon (.05-.10%) and grain size to optimize stress rupture properties. In heat treatment applications Alloy 800HT has further modifications to the combined titanium and aluminium levels (.85-1.20%) to ensure optimum high temperature properties. Alloy 800H/HT was intended for high temperature structural applications. The nickel content makes the alloys highly resistant to both carborisation and to embrittlement from precipitation of sigma phase. Please note that we have a minimum order value of £10,000.

Nickel based alloys are very useful materials for the manufacture of high quality tubing products. One of the key reasons is that they offer excellent corrosion resistance in both aqueous and high temperature applications. Nickel alloy tubes offer excellent corrosion resistance, high melting points and resistance to oxidationIn addition to their high melting points and resistance to oxidation and corrosion, nickel alloys are very ductile. Nickel based alloys have a higher ability to accept alloying elements in solid solution than other stainless steel or iron-based alloys. They cantherefore maintain higher metallurgical stability. The combination of high alloying with multiple elements can provide very good corrosion resistance in a wide range of environments while still maintaining good welding and forming characteristics. Please note that we have a minimum order value of £10,000.
