Metal Powders and Materials

Ferritic Stainless Steels

Ferritic grades - including 409L, 410L, 430L, 430LCb, 434L, and 434LCb - provide the lowest cost stainless steel options for corrosion resistance. Applications that use these grades include automotive exhaust system flanges, hot exhaust gas oxygen sensor bosses, antilock brake sensor rings, and mirror mounts.

Low Alloy Chromium Steels

The availability of dry hydrogen and nitrogen atmospheres and high temperature sintering, coupled with the need for reducing alloying costs, makes chromium-steel alloys ideal for many high-performance applications. The alloys provide a good balance of strength, toughness, ductility, and machinability.

Engineered Porosity (EP) Grades

In applications such as filters, breathers, sound attenuators and flame arrestors, control of the size, shape and distribution of the porosity is the critical. Where corrosion resistance is required along with high strength and/or high operating temperature, powder metal (PM) stainless steel and nickel-based alloys can provide the most cost-effective solution.

Duplex Stainless Steels

The mixed ferritic-martensitic structure of 409LNi provides better strength and hardness compared to straight ferritic materials and better sinterability and ductility compared to martensitic alloys. The mixed austenitic-ferritic alloys provide higher strength compared to straight powdered alloys while maintaining good corrosion resistance.

Austenitic Stainless Steels

Austenitic grades - including 303L, 304L, 304N, 304LSi, 309L, 316L, 316N, and 316LSi - provide better corrosion resistance compared to ferritic stainless steels.

Martensitic Stainless Steels

Martensitic grades - including 410, 420, and 440C - provide higher strength and hardness compared to either ferritic or austenitic grades.

Carbon, Copper and Nickel Steels

The iron-carbon, iron-copper, and iron-nickel steels are the “workhorse” alloys of the powder metal sintering industry. Designed for light to moderate loading, they are economical to process due to their ease of machinability, ease with which they may be pressed to moderately high densities, and their ability to be sintered effectively in a variety of atmospheres.

Low Alloy Molybdenum-Nickel Steels

The addition of molybdenum, nickel, and copper to iron improves the hardenability of steel. These nickel-steel alloys are amenable to sintering in a number of different atmospheres due to the ease with which the oxides of these elements can be reduced, resulting in their preeminent position in powdered metal alloys for higher strength steel.

Soft Magnetic Alloys

Sintered powder metal soft magnetic alloys - including Iron-Phosphorus, Iron-Silicon, and Iron-Nickel - are found in applications like tone wheels, relays, cores, sensor probe, armatures, solenoid components, and pole pieces. Magnetic properties benefit from high temperature sintering (HTS) above 2200 F (1200 C) in hydrogen, as compared to the standard PM sintering process (STS) in metal mesh belt furnaces at nominally 2050 F (1120 C).

Custom Blends

The powder metal process is flexible in its ability to provide custom material solutions. DSB Technologies has the expertise to develop tailored material chemistry and properties to meet specific application requirements and customer needs, like full density tool steels for high wear applications.
