Both 17-4 and 300 series stainless steel grades can be 3D printed/additive manufactured or wrought, depending on the application.
Direct metal laser sintering (DMLS), a type of additive manufacturing, drastically accelerates prototyping and product development, and makes previously unattainable geometries practical in production. Its high-power and high-density lasers melt and fuse metallic powders to create intricate components.
Wrought metal, however, is melted down, poured, and run through rollers to create strong, rigid stock for subtractive manufacturing. It is generally stronger than printed metals due to differences in microstructures both in PH 17-4 and 300 series stainless steels.
However, printed stainless steels are strong enough to support a variety of demanding applications. The speed and ability to create intricate geometries can make printing a preferred choice over wrought metal.
PH 17-4 is a martensitic stainless steel that is precipitation-hardenable and delivers an exceptional combination of strength, corrosion resistance, and good mechanical properties at temperatures up to 600°F. It is the most commonly used variety of stainless steel and serves a wide range of industries.
PH 17-4 stainless steel is preferred for its high strength, especially for industries like medical device manufacturers. Components that require exceptional hardness also benefit from PH 17-4 construction.
Many industries rely on PH 17-4 stainless steel for production, including aerospace, medical device, gas turbine, chemical processing and food processing.
Metalcraft Solutions commonly produces the following 17-4 stainless steel components across these industries:
While PH 17-4 often costs more than 300 series stainless steel, machining costs are often more affordable when compared to the 300 series.
PH 17-4 is commonly used in the following processes:
Known for durability, corrosion and temperature resistant properties, the 300 series stainless steel grades include 302, 304, 316, and others. Generally used for unmagnetized applications, 300 series stainless steels contain between 18 to 30% chromium and 6% to 20% nickel.
The 300 series stainless steels are incredibly tough and versatile and are used across a variety of industries. Unlike PH 17-4, they are not heat treatable but do offer a higher degree of corrosion resistance.
The 300 series stainless steels are tough, wear resistant, and hold their strength well at elevated temperatures.
Many industries requiring components that are highly durable, corrosion resistant, and nonmagnetic utilize 300 series stainless steel. The automotive, aerospace, medical device, construction, and food processing industries routinely rely on this material.
Metalcraft Solutions commonly produces the following 300 series stainless steel components across these industries:
The 300 series steel grades are generally more cost-effective than PH 17-4’s, but machining/manufacturing costs can come in at a higher price point.
300 series is commonly used in the following processes:
