As a result of the spray-forming process, the steel itself shows some excellent properties. For one, it contains very hard primary carbides, which together with the nitrogen from the spray process increase the wear resistance of the steel.
The process also ensures very clean steel due to the pouring and filtering method involved. Lastly, spray-formed steel shows excellent impact strength, compression strength and surface treatment properties compared to conventional tool steels.
Spray-formed steel has a very homogeneous structure, which secures even wear under usage, and allows for even machining during both the construction and maintenance phases. It also is completely free from macro-segregation (cracks) and in many cases even free from micro-segregation.
As an additional help to moldmakers, the spray-formed steel gives a higher form stability of the tool without the need for machining and stress annealing. Finally, the standard heat treatment procedures used for conventional steels can be used unchanged for spray-formed steels.
Using spray-formed steels gives additional benefits if the moldmaker also is the owner of the company he works in, the company then being a supplier to or subcontractor of larger companies where the molds are used in the production lines. These moldmaking companies will be able to supply molds made of the newest generation of steels with their unique properties, which in turn opens up for new potential customers. Additionally, they will be able to set a higher price level for tools and molds due to the superior steel properties.
thanks for sharing, I got new knowledge from it
