Why steel is the standard
T304 was developed for chemical and aerospace industries — where high temperature resistance and aggressive environments matter. Perfect material for Ukrainian roads and winter salt.
Reagent resistance
Winter salt won't damage the surface. Critical on Ukrainian roads.
TIG welding
Argon-shielded sealed seams with no slag.
Repairability
Any shop can re-weld a seam. No specialty service needed.
Lifespan
100,000+ km with no visible wear. Real owner experience.
When the upcharge makes sense
40-45% lighter
On a supercar — minus 8–12 kg. Critical for track days.
Working temp up to 900°C
No property loss under sustained load.
Doesn't rust principally
No pores where corrosion starts. Salt-water resistant.
Golden patina
After first heat cycle — distinctive visual. Wow factor.
