SS 301 is an austenitic Chromium-Nickel stainless steel capable of attaining high strength with moderate cold working. The combination of high strength and good ductility makes it suitable for numerous mechanical switches as well as surgical instruments, metal stampings and electronic and computer spring components.. The alloy is readily formed in the annealed temper. Ductility decreases with increased cold rolled strength but not to the degree that would occur with SS 302. It is not recommended for deep drawing. SS 301 can be welded by all conventional processed except oxy-acetylene. The weld should not make contact with electrolytes to prevent intergranular corrosion. SS 301 is resistant to atmospheric corrosion and is additionally resistant to mildly corrosive mediums. The combination of narrow strength bands and close thickness tolerance provided by Hamilton Precision Metals is the key to repeatable response characteristic in spring and switch applications.

Alloy 209 is a fully austenitic nitrogen strengthened stainless steel, having twice the yield strength and superior corrosion resistance at room temperature when compared to 316/316L or 317/317L stainless steels. This grade does not become magnetic when cooled to sub-zero temperatures or to a cold working process and has high resistance to sulphide stress corrosion cracking in both annealed and cold worked/ cold worked & aged form up to 30 HRc hardness. Please note that we have a minimum order value of £10,000.

Ti Grade 9 is a near alpha, alpha-beta alloy, sometimes referred to as “half-6-4.” It offers 20 to 50% higher tensile strength than the commercially pure titanium at room and elevated temperatures. It is much more amenable to cold working than Ti 6AI/4V alloy and can be cold worked 75 to 85% to result in moderately high strength and good ductility The alloy can be formed from the annealed temper. Severe forming may be aided by an intermediate stress relief. Stress relieving may be appropriate after severe cold forming to remove residual stresses. Weldability and corrosion resistance is very similar to commercially pure titanium. Welding should be performed with inert gas shielded arc or spot welding.Welding with active gases, coatings, or fluxes must be avoided to prevent embrittlement.

Welded and redrawn tube manufacturing employs elements of both the welded and seamless processes. A welded and redrawn tube is welded in a conventional manner but then transferred to our seamless mill, located in the same factory. Here the product is redrawn to achieve a welded and redrawn finish. The objective of redrawing is to achieve homogenisation of the weld following annealing by cold working. This refines the structure of the weld resulting in improvements that include: Better corrosion resistance Improved fatigue life Higher mechanical integrity Please note that we have a minimum order value of £10,000.

21Cr-6Ni-9Mn is a high manganese nitrogen strengthened, austenitic stainless steel.

Please note that we have a minimum order value of £10,000.

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

L-605™ is a nonmagnetic cobalt-based chromium-tungstennickel alloy that has excellent corrosion and oxidation resistance, and high strength at both room and elevated temperatures. Through work hardening, high strength levels can be obtained. L-605™ has a minimal heat treatment response, but can be used in the cold worked and aged condition. Applications include medical implant devices, springs, valves, and engine components for the aerospace industry. As a result of its high tungsten content, L-605TM is radiopaque, which is beneficial for implant medical devices, such as stents. Because of the alloy’s high work hardening rate, only minimal reductions can be taken before solution annealing will be required. L-605TM is very resistant to oxidation and scaling at elevated temperatures, and is nonmagnetic in all conditions. L-605™ is produced by vacuum induction melting followed by electroslag remelting (VIM-ESR), and as such, has a low nonmetallic inclusion level.

Ti 6Al/4V (Titanium Grade 5) is the most widely used of all the alpha-beta titanium alloys accounting for more than 50% of total titanium usuage. It is typically used in the annealed condition, at service temperatures through 400°C (750°F). Ti 6Al/4V is welded with matching or with ELI filler wire. Ti 6Al/4V is significantly stronger than commercially pure titanium while having the same stiffness and thermal properties excluding thermal conductivity, which is about 60% lower in Grade 5 Ti than in CP Ti. Amongst its many advantages, it is heat treatable. This grade is an excellent combination of strength, corrosion resistance, weld and fabricability. In consequence, its uses are numerous such as for military aircraft or turbines. It is also used in surgical implants. Generally, it is used in applications up to 400°C to improve ductility and toughness in cold-worked condition. Please note that we have a minimum order value of £10,000.

Our ability to strategically blend alloys allows us to offer specifically blended materials such as highly alloyed Nickel-Tungsten strip (NiW) for superconducting substrates. These custom alloys are available at customer-specified chemistries and cold work. The use of Tungsten in these alloys produces a flexible strip with preferred magnetic characteristics for superconducting wire. High Temperature Superconductors Our Nickel Tungsten substrate material is used in high temperature superconductors (HTS) to carry high-density electrical currents with very little energy dissipation. This property makes high temperature superconducting wire suitable for sectors such as power generation and transmission, electric motors, and high magnetic field generation. Nickel and nickel alloys are used as substrate materials because they are flexible to the thermomechanical processing of the wire making process.
