Maher Limited
About us
Maher is your first choice for high-strength, high performance alloys and precision machined components. Drawing from our legacy in steel stockholding, we offer an extensive product range of Nickel, Copper, Titanium and other specialist alloys, all complemented by our value-added services.
We carry a comprehensive range of stock in metric and imperial sizes depending on the grade of material. All our bars come with a bright machined finish, meaning you can order close to your finished size and minimise waste. Along with our in-house machine shop, we also work closely with local forges and grinding companies that means we can offer bespoke sizes and shapes as required.

Products & services
Alloy 718 Round Bars
Alloy 718 is a high strength, corrosion resistant nickel chromium alloy, initially developed for the aerospace industry and still considered the material of choice for the majority of aircraft engine components. Its excellent strength and corrosion resistance have been recognised by the oil industry and it is now widely used in this field Industry Specifications include: API6ACRA AMS 5662 AMS 5663 NACE MR0175 ISO15156 ASTM B637 UNS N07718
Alloy 625 Round Bars
Alloy 625 is a nickel-chromium alloy which gains its stiffening effect through molybdenum and niobium additions, therefore eliminating the need for this alloy to be aged. It has superior resistance to a wide range of corrosive environments as well as the high temperature effects of oxidation and carburisation. Alloy 625 is excellent for sea-water applications, having freedom from pitting and crevice corrosion, high corrosion fatigue strength and resistance to chloride-ion stress corrosion cracking. This alloy also has high tensile, creep and rupture strength, fatigue and thermal fatigue strength and oxidation resistance, making it suitable for aircraft engine exhaust systems, housing engine controls and aircraft ducting systems. It is also used in the nuclear field for reactor cores, control rod components in nuclear water reactors. Industry Standard Include: ASTM B164/564 BS 3076 NA21 UNS N06625 AMS 5666 NACE MR0175/ISO15156 Werkstoff Nr. 2.4856
Alloy K500 Round Bars
Alloy K500 is a nickel-copper alloy which combines the excellent corrosion resistance of Alloy 400 with higher strength and hardness obtained through the addition of aluminium and titanium to the nickel- copper base. It has excellent low temperature properties with tensile and yield strengths increasing with decrease in temperature, while ductility and toughness are virtually unimpaired. There is no ductileto-brittle transformation even at temperatures as low as liquid hydrogen, making it suitable for cryogenic applications. The corrosion resistance of Alloy K500 is equivalent to that of Alloy 400 except that in the aged condition, it has a greater tendency towards stress-corrosion cracking in some environments. It is resistant to a sour gas environment and has very low corrosion rates in high velocity seawater, making it ideal for marine applications. Industry Standards Include: ASTM B865 BS 3076 NA18 1989 UNS N05500 NACE MR0175/ISO15156 (Hot worked only) Werkstoff Nr. 2.4375
Alloy A286 Round Bars (660B/D)
Alloy A286 is a precipitation hardenable iron-based super alloy with additions of molybdenum and titanium nickel-chromium. Nickel and chromium additions provide excellent corrosion and oxidation resistance up to 704°C for long term service, up to 816°C for short term service (which is similar to that of 310 stainless) and up to 982°C for intermittent service. Alloy A286 can also be used in low temperature applications that require a ductile, non-magnetic, high strength material at temperatures above room temperature and down to minus 196°C. The chromium, nickel and molybdenum contents are similar to those of some austenitic stainless steels, making its aqueous corrosion resistance comparable to that of 316L austenitic stainless steel. Alloy A286 has excellent fabrication characteristics comparable to austenitic stainless steels and is readily fabricated by standard procedures. Industry Standards Include: ASTM A453/A453M - 16 Gr 660 Classes B & D ASTM A638/A638M – 10 Gr 660 Type 2 NACE MR0175/ISO15156 Werkstoff Nr 1.4980 UNS S66286 AMS 5732
