Machine builders of company "Severstal" have confirmed the suitability of metal powders for 3D printing

Press Releases

the Engineering centre "SSM-Tyazhmash" (part of "Severstal
Russian steel") has successfully passed the research of possibilities of application
vodorazdelny powders produced in the 3D printing technology.
research on the technology of selective laser melting (SLM) and direct
laser growing (DLD) conducted by the experts of Saint-Petersburg
Polytechnic University.


was Investigated vodorazdelnye powders 304, released in the workshop series
the production of "SSM-Tyazhmash". The work was carried out in two stages: vodorazdelnye
powders were investigated in initial state and after plasma spheroidizing.
the Second involves the melting of powder particles in the jet plasma for
subsequent giving of the spherical form.


the samples showed the result for yield strength and the limit
of strength comparable to the requirements of normative-technical documentation at
this steel, and if the SLM technology even higher. Using the powder after the
plasma spheroidizing allows you to achieve a more stable mechanical
characteristics, enhances the qualitative characteristics of the part.


"the Builders "SSM-Tyazhmash" mastered the technology of additive manufacturing in 2018. In
for two years with the help of a 3D printer in the shop of blank production
was released more than 200 models, plastic casting units. In
the future, we plan to develop 3D printing with metal powders. This
study proves that we can safely use
vodorazdelnye powder of its own production. This initiative responds
our vision in implementing the long-term goals strategic priorities
"the Leadership on cost reduction," - said the Director repairs division
"Severstal Russian steel" Sergey dobrodey.


background:


the Engineering centre "SSM-Tyazhmash" produces powders of different brands have already
more than a quarter century and is the only producer of iron powders
Russia. In 2019 industry exhibition "Metal Expo", the company received
gold medal for the development of diffusion-alloyed powders that do not have
analogues in Russia.
