Elastoforming, Elastoformed Blades, Energy Production

A success made possible by elastoforming

For the energy sector, Inoxveneta successfully applied the elastoforming process to shape “heat-resistant” stainless steel AISI 309 (1.4828).

In the field of energy production, reliability is a critical factor, as the gas burners in question are installed in power generation plants around the world and often operate under extreme conditions.

Customer’s Requirement

Our customer asked us to evaluate the feasibility of producing blades for large gas burners using AISI 309 sheet metal. This material, an austenitic stainless steel classified as “heat-resistant” due to its high-temperature durability, is extremely tough and difficult to process.

In fact, with previously tested forming methods, the customer was unable to produce the blade according to the required geometry or with sufficient process repeatability. This led to significant challenges in assembly, high production costs, and reliability and performance issues in the final burners.

The Solution: Elastoforming

Inoxveneta overcame these production challenges in a very short time using the elastoforming process by:

analysing the formability characteristics of the base material
designing a dedicated elastoforming tool system
optimising the process through quick tool adjustments

All while meeting extremely short delivery times.

The customer was fully satisfied, as the elastoformed blades produced by Inoxveneta met all the required parameters: dimensional accuracy, process repeatability, simplified assembly, significant cost reduction, and a marked improvement in the reliability of the final product.
