AMETEK SPECIALTY METAL PRODUCTS - Advanced Metallurgical Products for Critical Applications.

In recent years, as Powder Metallurgy (P/M) Stainless Steels have become more prevalent in numerous markets, AMETEK has invested in production capability and technology stainless steel powders. Among the results of these efforts are AMETEK’s patented Ultra Stainless Steels™ which are produced by alloying conventional austenitic compositions with a small amount of tin and copper. This combination of metals results in a marked improvement in corrosion resistance when compared to typical austenitic P/M parts while maintaining mechanical properties.

The 300 Series Powders are austenitic stainless steels typically used for powdered metallurgy (P/M) press and sinter applications to make near net shape parts for a variety of industrial applications. Stainless steel powder 303L is a free machining, austenitic grade that offers moderate corrosion resistance. This stainless steel is sintered in either a partial vacuum or a hydrogren atmosphere to improve ductility and corrosion resistance. 303 Stainless steel powder is a sulfurized grade that is an excellent option for parts that require secondary machining operations, such as food service equipment, pump components and nonmagnetic housings.

Stainless steel powder 304L is a corrosion resistant material that exhibits good property stability below 1000°F. 304L powder is often the most practical stainless steel choice for parts that need the benefit of an austenitic grade. 304 Stainless steel exhibits better overall corrosion resistance than 303 grade. This material is a good choice for parts that will not be subjected to demanding machining operations. A major benefit of this material is the balance of good material performance and economical cost. The 300 Series Powders are austenitic stainless steels typically used for powdered metallurgy (P/M) press and sinter applications to make near net shape parts for a variety of industrial applications.

Stainless steel powder 316L offers the highest degree of corrosion protection that is available in a standard P/M stainless steel grade. It provides very good strength at extremely high temperatures. AMETEK’s 316 grade stainless steel powder includes many fully customized powder specifications by varying lubricant type, content and particle size. We manufacture high quality 316L powders to fit your applications. 316L stainless steel powders are used in stainless steel flakes and are also used for paint additive manufacturing and chemical filtration. The 300 Series Powders are austenitic stainless steels typically used for powdered metallurgy (P/M) press and sinter applications to make near net shape parts for a variety of industrial applications.

Stainless steel powder 409L/409CB is a ferritic, weldable grade of stainless steel with key performance features, including high compressibility, enhanced green strength and good sinterability. This stabilized grade provides excellent corrosion resistance and has the capacity to provide high-caliber mechanical properties due to the high temperature sintering response. 409L/409CB’s versatility also results from Cb being less prone to oxidation than Ti. In addition, the oxide is unable to combine with carbon and the Cb forms a stable carbide which prevents coarsening of carbides and grains in the weld’s HAZ. 409L/409CB Stainless steel is a prime candidate for automotive exhaust system applications, among other uses. 409LNI Powder has added nickel for new automotive specifications. Ferritic stainless steel powdered metallurgy (P/M) technology is specified for longer-term performance and reliability. Good atmospheric and saline corrosion

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

Stainless steel powder 430L is a Low-carbon ferritic stainless steels, in mildly corrosive environments or atmospheric exposures, have corrosion resistance approaching that of some nickel stainless steels. These alloys are oxidation resistant at elevated temperatures. Type 430 alloys are ductile and do not work-harden readily. The toughness—defined as resistance to crack propagation or notch strength—of ferritic steels is relatively low, and the ductile-to-brittle transition temperature is at or above room temperature. The corrosion and oxidation resistances of the ferritic steels are directly related to their chromium content. The 17% Cr 430 steel alloys have good corrosion resistance to atmospheric conditions. 430 stainless steel alloys are used in a variety of applications where corrosion resistance is more important than strength. These alloys are resistant to attack in a wide variety of corrosion media.

Stainless steel powder 434L is a low-carbon ferritic steel powder, in mildly corrosive environments or atmospheric exposures, have corrosion resistance approaching that of some nickel stainless steels. These alloys are oxidation resistant at elevated temperatures. Type 434 stainless steel alloys are ductile and do not work-harden readily. The toughness, defined as resistance to crack propagation or notch strength, of ferritic steels is relatively low, and the ductile-to-brittle transition temperature is at or above room temperature. The corrosion and oxidation resistances of the ferritic steels are directly related to their chromium content. The 17% Cr 434 steel alloys have good corrosion resistance to atmospheric conditions. These alloys are used in a variety of applications where corrosion resistance is more important than strength.

Hardfacing Powders are manufactured to have the precise size, shape, and chemistry required for optimal thermal spraying characteristics. Our powders are available in a wide variety of alloys to give the workpiece desired finished qualities - whether it’s good machinability, abrasion resistance, corrosion resistance, ductility, hardness, or high strength. No matter the application, we have a powder that can be manufactured to your exact specifications and meet your coating needs. Hardfacing Process Hardfacing or surface coating is a process of spraying or welding metallic powders onto a workpiece or substrate to give it a specific hardness, wear resistance, or corrosion resistance. This process requires the appropriate alloy and particle size distribution for a specific deposition technology. Appropriately selected powders yield the best properties and manufacturing efficiencies.
