Titanio Grado 2
UNS R50400
Resumen
The workhorse commercially pure titanium grade — balancing strength, ductility, and corrosion resistance at a reasonable cost. The most widely used titanium grade for industrial applications. Approximately 50% stronger than Grade 1 with only a slight reduction in formability. The standard material for seawater piping, shell-and-tube heat exchangers, and pressure vessels in chloride service.

Resistencia a la Corrosión
Virtually immune to corrosion in natural water, seawater, and steam to 315°C. Outstanding resistance to oxidizing media (nitric acid, chlorine gas, chlorine dioxide). Resistant to pitting, crevice corrosion, and stress corrosion cracking in all chloride environments. Not suitable for strong reducing acids (HCl, H₂SO₄) or anhydrous chlorine. Can ignite in dry chlorine gas.
