Since our last newsletter, the following chapters on new alloys and one revised alloy have been added to our databases:


  • 904L - 904L is a non-magnetic super austenitic stainless steel that was originally developed for use in sulfuric acid environments. It is resistant to stress corrosion cracking and crevice corrosion. It also offers excellent formability, toughness, and weldability.
  • Alloy 690 - Alloy 690 is a high Cr, austenitic, solid-solution nickel-base alloy which has excellent resistance to corrosion in aqueous environments and high temperature atmospheres. It is extensively used in the nuclear industry and petrochemical industry for heat transfer tubes, baffles, sheets and other hardware.
  • Alloy 825 - Alloy 825 is a nickel-iron-chrome alloy with exceptional resistance to general corrosion in strong acids, high resistance to pitting and crevice corrosion cracking and intergranular corrosion resistance. Alloy 825 has been successfully used in a variety of applications in the chemical processing and oil and gas industries.
  • F6NM (wrought version) and CA6NM (cast version) - F6NM is a low C super martensitic stainless steel. It has moderate corrosion performance, good strength, good toughness, and much better weldability than most martensitic stainless steels. It is ferromagnetic and, as a result, can be checked with magnetic particle inspection methods. It is used in many applications in the chemical processing and petrochemical industries.
  • Zr 702 and 705 - These are the two most widely commercially used alloys of Zirconium (Zr). They were originally developed for use in nuclear reactors as cladding for uranium fuel and for reactor core components such as fuel rod spacers and water channels. Now the chemical processing industry utilizes Zr and its alloys for reaction columns, heat exchangers, pumps, and other components in severely corrosive environments.


  • L-605 revision - L-605 is a high temperature cobalt base superalloy that combines solid solution strengthening with second phase strengthening by precipitated carbides. The alloy has excellent resistance to sulfidation and high strength and oxidation resistance up to 1800F. It is an established alloy used in commercial and military turbine engines.
  • 430 Ferritic Stainless Steel - This low-carbon, nickel-free ferritic stainless steel is one of the most widely used of the non-hardenable, straight chromium stainless steels. It has good corrosion resistance and stress corrosion resistance, including high resistance to nitric acid, sulfur gases, and various organic and food acids. The Powder Metal grade, 430L, is widely used for structural and metal injection molded components, and additive manufacturing.
