Stainless Steel Stainless Steel 420

In WAM® applications, ER420 wire feedstock offers superior abrasion resistance in mildly corrosive environments and atmospheric conditions. Commonly used for applications requiring resistance to wear, abrasion, and moderate impact, ER420 provides high strength, hardness, and wear resistance, making it suitable for the Wire Additive Manufacturing of components traditionally made from martensitic stainless steels, such as turbine blades, valves, and pump shafts.

When combined with ARCEMY® and the WAM® process, ER420 is suitable for the production of drilling equipment, valves, pumps, and pipelines often seen in the Oil & Gas industry. It is also suitable for tooling needs, where toughness may be required. It could be used in power generation industries where parts are often required to operate under high temperatures, high-stress, and high-load conditions.

Mechanical properties, including tensile and yield strength, can be improved through specific parameter control provided by AMLSoft™ for ARCEMY® metal 3D printing systems. AMLSoft™ enables management of process parameters, such as welding current, travel speed, and shielding gas, are carefully controlled to ensure successful manufacturing outcomes.
