Ti Gr 1 / 3.7025

Unalloyed titanium offering optimum ductility and cold formability with useful strength, high-impact toughness and excellent weldability. This makes this grade suitable for the manufacture of components in weight-saving structures with reduced mass forces and also for components requiring high corrosion resistance. In addition, thermal stresses in titanium structures are lower than in other metallic materials, due to the low thermal expansion of titanium.

Material Data Sheet

Material designation 3.7025
EN Material Symbol Titan Grade 1

Filler metal (for welding with titanium Gr 1

Grade 1 has very good weldability. Being substantially single-phase material, the microstructure of the alpha phase is not affected greatly by thermal treatments or welding temperatures. Therefore, the mechanical properties of a correctly welded joint are equal to, or exceed those of the parent metal and show good ductility
