Desktop Metal Introduces DM HH Stainless Steel

Desktop Metal has released DM HH Stainless Steel (DM HH-SS), a custom stainless steel alloy that combines high strength and hardness with corrosion resistance, for additive manufacturing on the Production System platform.

Customers can now leverage the Production System’s Single Pass Jetting (SPJ) technology to produce DM HH-SS components at scale across a range of industries where high strength and hardness are required, including oil & gas, automotive, consumer products, and medical devices, the company reports. With the addition of this new alloy, the Production System can now print 10 qualified metal materials.

DM HH-SS is a custom, heat treatable-alloy that combines the tensile strength, ductility and corrosion resistance of 13-8 PH stainless steel with improved hardness comparable to low-alloy steels, such as 4140, the company reports. These attributes make DM HH-SS an enabling material for companies looking to eliminate use of low-alloy steels, according to Desktop Metal. DM HH-SS is also made for conformally cooled injection tool core and cavity applications. 

“Our materials science team is working diligently to develop innovative materials that meet the demanding applications needs of our customers in a cost-effective way,” says Jonah Myerberg, co-founder and chief technical officer, Desktop Metal. “DM HH-SS is a compelling alternative to 17-4 PH stainless steel that improves upon its mechanical properties while maintaining corrosion resistance, making it suitable for critical components that previously required the use of low-alloy steels for their high hardness and strength.” 

Derived from 13-8 PH stainless steel (UNS 13800) and custom-developed by Desktop Metal, DM HH-SS has been qualified and fully characterized for printing on Production System technology.

In addition to DM HH-SS, the Production System materials library includes commercially pure copper, D2 tool steel, 420 stainless steel, nickel alloy IN625, 4140 low-alloy steel, 316L stainless steel, and 17-4 PH stainless steel. The platform also supports several customer-qualified materials, including silver and gold, and Desktop Metal plans to add additional metals to its portfolio, including tool steels, stainless steels, superalloys, and more.
