Alloy 600 is a nickel-chromium alloy designed for use from cryogenic to elevated temperatures in the range of 2000°F (1093°C). The high nickel content of the alloy enables it to retain considerable resistance under reducing conditions and makes it resistant to corrosion by a number of organic and inorganic compounds. The nickel content gives it excellent resistance to chloride-ion stress-corrosion cracking and also provides excellent resistance to alkaline solutions. Its chromium content gives the alloy resistance to sulphur compounds and various oxidizing environments. In strong oxidizing solutions like hot, concentrated nitric acid Alloy 600 has poor resistance. Alloy 600 is relatively un-attacked by the majority of neutral and alkaline salt solutions and is used in some caustic environments. The alloy resists steam and mixtures of steam, air and carbon dioxide. Please note that we have a minimum order value of £10,000.

Alloy 22, is a versatile austenitic nickel-chromium-molybdenum-tungsten alloy with enhanced resistance to pitting, crevice corrosion and stress corrosion cracking. The high chromium content provides good resistance to oxidizing media while the molybdenum and tungsten content give good resistance to reducing media. This nickel alloy also has excellent resistance to oxidizing aqueous media including wet chlorine and mixtures containing nitric acid or oxidizing acids with chlorine ions. Alloy 22 has resistance to oxidizing acid chlorides, wet chlorine, formic and acetic acids, ferric and cupric chlorides, sea water, brine and many mixed or contaminated chemical solutions, both organic and inorganic. This nickel alloy also offers optimum resistance to environments where reducing and oxidizing conditions are encountered in process streams. This is beneficial in multi-purpose plants where such “upset” conditions occur frequently. Please note that we have a minimum order value of £10,000.

SS 305 is an austenitic Chromium-Nickel stainless steel with excellent corrosion resistance, and is suitable for very severe cold forming operations. A high nickel content reduces the work hardening rate so that it can be formed into electronic components and remain non-magnetic. The alloy is readily formable and work hardens slowly.It has good resistance to nitric and sulfuric acid solutions although it will not resist halogen acids. The alloy can be satisfactorily welded, brazed, and soldered. Available Sizes: SS 305 is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005” to 0.050” (0.0127 mm to 1.27 mm) in widths up to 12.0” (304.8 mm). It is also available in foil as thin as 0.000200” (0.00508 mm) in widths of 4.0” (101.6 mm) maximum. The material conforms to ASTM A240, QQS-766, and UNS S30500.
