NEOVAC, a joint venture between German plantmaker SMS group GmbH and Swiss-based SITIZN GroupHolding AG, has unveiled a new steel strip coating technology. This innovation is tailored specifically for high-strength and ultra-high-strength steels, sectors where conventional high-temperature coating processes oftenfail.
Environmental and efficiency benefits
Traditional coating technigues rely on high temperatures, which can damage the microstructure of ultra-high-strength steels. In its statement, NEOVAC said that the new cold vacuum process preserves material integritywhile ensuring a uniform, high-quality coating.
The vacuum coating system can run entirely on renewable electricity, making it carbon-neutral. Compared toconventional processes, it delivers higher energy efficiency, lower raw material consumption thanks to thinneryet stronger coatings, and reduced environmental footprint
NEOVAC stated that this positions its process as a sustainable alternative aligned with Europe''sdecarbonization goals.
Pilot line established at Karlstein site
At Karlstein, a 170-ton pilot vacuum coating line hasbeen commissioned. lt uses a three-stage process thatconsists of plasma pre-treatment, magnetron-based pre-coating and plasma-enhanced evaporation (thermal zincevaporation at 600''C, deposited below 200°C).
Tests already show success: UHSS with tensilestrengths up to 1,500 MPa have been coated withoutaffecting structural or chemical properties.
Toward industrial scalability
The system is now ready for serial production. NEOVAC said it is preparing for continuous scaling up ofproduction, adding that its long-term goal is to serve global downstream industries, including automotive,aerospace, construction, and energy.
