Engineering alloys for a low-impact future
As the global steel industry accelerates efforts to decarbonise and optimise performance, new materials can play a role in sustainable innovations. A recently released alloy suitable for high-pressure industrial applications is a good example.
The new grade offers high tensile strength combined with sustainability advantages.

Ukraine-based Centravis is taking bold steps toward sustainable innovation. The company has introduced Balev Steel ®, an advanced material developed to serve high-pressure industrial applications while dramatically reducing the environmental footprint of production. With its enhanced strength-to-weight ratio and sustainable production parameters, the new steel family marks a decisive shift in how seamless tubes and pipes can be engineered for both safety and sustainability.
Mechanical strength meets environmental strategy Engineered specifically for industries such as hydrogen fuel systems, aerospace, and automotive, Balev Steel ® allows for thinner wall designs, significantly reducing material
Polina Kazarina, Product Manager Precision Tubes at Centravis:“ We created Balev Steel ® as a response to the question: how can we advance technical performance without compromising our environmental ethics?” usage while maintaining safety and performance standards. The company has confirmed that Balev 304L ® and Balev 316L ® achieve tensile strengths twice that of traditional TP304L and TP316L grades, while retaining superior formability compared to duplex alternatives. What makes this material stand out isn’ t just its mechanical properties, but also its sustainability considerations. Lighter constructions mean less raw material is consumed and less energy is used during manufacturing, reducing lifecycle emissions.
Thermal performance and durability A key advantage of Balev Steel ® lies in its reliable microstructure. Thanks to advanced heat treatment processes, the steel maintains a consistent austenitic phase even at cryogenic temperatures as low as-196 ° C. This makes it well-suited for applications in extreme thermal environments where structural integrity and long-term performance are critical.
Cost-efficient sustainability In terms of financial sustainability, Centravis highlights that the economics of the alloy compare favorably to lean duplex options. Austenitic-based Balev grades offer up to 35 % cost savings over materials like UNS S31803, UNS S 32304 and UNS S32304, driven primarily by weight reduction and production efficiency. For project engineers and procurement teams, this creates a rare win-win: environmental benefit and cost reduction.
Driving Industry Transformation The development of Balev Steel ® aligns with Centravis’ broader commitment to sustainable development, particularly within its production base in Nikopol, Ukraine. The company is actively working to reduce its environmental impact while enabling clients to meet stringent global standards for emissions and resource efficiency.“ It’ s about more than steel,” says Dr Balev.“ It’ s about building a future where industrial performance and ecological mindfulness go hand in hand.” Balev Steel ® presents one example of how materials engineering is adapting to the dual pressures of technical specification and ecological responsibility. Its use across multiple sectors underscores the growing importance of integrating mechanical innovation with sustainable practices. While ongoing evaluation is required to assess long-term field performance across different industrial environments, current data suggests that such material strategies may play a meaningful role in reducing the resource intensity of highpressure applications.
The man behind the metal
Dr Andrew Balev, Head of R & D at Centravis, is a member of the Stainless Steel World Conference 2025 Steering Committee. As a technical expert with 20 years of experience in mechanical and material engineering, Andrew is also a developer of next-generation materials BALEV 304L and BALEV 316L for automotive, hydrogen and industries where high and ultra-high pressure are applied.
