The difference between deep drawing of titanium strip and plate exchangers

The primary differences between titanium strip for deep drawing and that for plate-to-plate heat exchangers lie in their intended applications, performance requirements, and process standards. Although both are cold-rolled titanium strips, their distinct application scenarios result in significant variations in mechanical properties and processing accuracy.

Different uses

Titanium strips for plate heat exchangers: specifically designed corrugated plates for manufacturing plate heat exchangers, typically operating in highly corrosive media such as chemical processing, power generation, and seawater desalination, with a strong emphasis on corrosion resistance and sealing stability.
Titanium strip for deep drawing: Used to manufacture components that require deep-draw forming, such as pressure vessels, aerospace structural parts, or housings for medical devices. The material must exhibit excellent resistance to cracking, fracture, and deformation failure under complex deformation conditions.

Performance Requirement Differences

Higher elongation and cupping value: Titanium strip for plate heat exchangers typically requires a post-fracture elongation of ≥55% (compared with ≥30% for conventional titanium plates) and a cupping value of ≥9.5 mm, to ensure that the material does not crack during deep-drawing into corrugated shapes. Titanium strip for deep-drawing applications also demands high elongation, though the specific requirements vary depending on the part geometry and are therefore more customized.
Stricter thickness control: Titanium strip for plate heat exchangers typically has a thickness of 0.5–0.7 mm and demands extremely high dimensional accuracy and surface finish to ensure uniform contact and tight sealing between heat-transfer plates. In contrast, titanium strip for deep drawing covers a broader thickness range (0.1–1 mm) and places greater emphasis on overall formability rather than strict dimensional stability.

Production processes emphasize different aspects.

Titanium strips for plate heat exchangers emphasize batch-to-batch consistency and standardization, as they are produced via large-scale, continuous stamping, which requires stringent control over grain structure uniformity and the range of strength variation.
For deep-drawing titanium strips, the focus is on localized formability, which may require specialized annealing processes or surface treatments to meet the stretching requirements of complex dies.
