AMETEK offers a range of wear resistant tool steel powers used in P/M, MIM, and metal additive manufacturing. Tool steels use a combination of C, Cr, Mo, V, and W in an Fe based alloy to generate a carbide microstructure in the metal alloy. Powder Metallurgy (P/M) tool steels offer the highest grade of performance, especially in respect to toughness, due to the extremely fine and uniform distribution of carbides resulting from the atomization process. AMETEK offers multiple grades in the M, D, and T series of tool steels including M3-5, D-2, and T-15 among others. Each tool steel is optimized for its respective purpose to give exceptional properties. Some tool steels, such as our premium T-15 grade, can result in hardness near 70 HRC when appropriately processed and heat treated. Materials that have been routinely produced include M-2, M3-2, M3-5, M4-2, D2, and T15.

Titanium for Implantable Medical Devices Ti 6Al/4V ELI sheet has found application in medical implants owing to its excellent biocompatibility, high strength, and MRI compatibility. In the cold rolled and annealed temper the material will not exhibit a continuous alpha network at prior beta grain boundaries or a continuous alpha case layer on the surface. Owing to the alloy’s high strength and low ductility, it is difficult to cold draw into finished shapes. Hot forming has been found to be effective.

Our NORSOK-approved Super Duplex alloy 2507 tubes (UNS 32750) are custom-engineered for the most aggressive subsea and downhole oil and gas applications. Advantages include: NORSOK-approval Made to order in specialist non-standard sizes Superior strength and corrosion resistance Short lead times Small batch sizes With 80 years engineering expertise, we specialise in manufacturing corrosion resistant Super Duplex tubes for the increasing hostile temperature and operating environments. Greater Corrosion Resistance Than Standard Duplex Grades Super Duplex stainless like S32750, is a mixed microstructure of austenite and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades. The main difference is that Super Duplex has a higher molybdenum and chromium content which gives the material greater corrosion resistance than standard duplex grades. Please note that we have a minimum order value of £10,000.

Commercially Pure (CP) titanium is an unalloyed titanium grade with a close-packed hexagonal (CPH) crystal structure at room temperature known as alpha phase structure. It has good formability, weldability, ductility, and corrosion resistance combined with moderate strength. Grade 2 titanium has slightly increased higher mechanical properties when compared to Grade 1. It is used principally in aerospace, automotive, chemical plants, marine environments, architecture structures & medical applications. Please note that we have a minimum order value of £10,000.

Stainless steel powder 410L is a magnetic grade of stainless steel exhibiting fair corrosion resistance and decent high temperature sintering response as well as good green strength and high compressibility. 410 Steel powder is a magnetic grade of stainless steel. An excellent candidate for automotive sensor ring and mirror mount applications, P410L exhibits fair corrosion resistance and a decent high temperature sintering response. Major performance features of this stainless steel include green strength and high compressibility. Carbon Additions: Fractions of graphite can be admixed for increase hardenability in 410 SS powder. Ferritic stainless steel powdered metallurgy (P/M) technology is specified for longer-term performance and reliability. Good atmospheric and saline corrosion resistance, hot oxidation resistance and elevated temperature yield strength, at the most economical costs are key reasons for using 400 series stainless steel

Filter Powder Expertise We manufacture filter grade powders that are specially atomized to give the highly irregular shape required for precise filtration. Our plant has been producing water atomized powders for sintered

Titanium exhibits a unique combination of properties including excellent corrosion resistance, high temperature resistance, and outstanding strength to weight ratios. Titanium is produced as commercially pure or alloyed. Commercially pure titanium is typically used in implantable medical applications whereas the titanium alloys are produced with the addition of vanadium or aluminum for applications such as aerospace. Hamilton Precision Metals processes strip and foil products in Titanium CP (Grade 1, Grade 2, Grade 4) and Titanium 3Al-2.5V (Grade 9).

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.

Ti 3AI/2.5V (Titanium Grade 9) alloy 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. Furthermore, it is weldable as the commercially pure grades and has excellent resistance to torsion and corrosion.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. Please note that we have a minimum order value of £10,000.
