Commercially pure titanium Grade 1

Titanium Grade 1 is a commercially pure titanium grade that is mainly applied because of its high corrosion resistance to general corrosion and pitting in saline or oxidizing acid solutions and because of its decent resistance to mineral acids. This corrosion resistance is due to the very passive, tight and dense oxide film that is immediately formed on the metal when the metal is exposed to air or an oxidizing environment. This provides titanium with the so-called self-healing effect; large or small damages to the oxide skin are immediately repaired. A condition is that oxygen must be present in the environment. 

Titanium Grade 1 is characterized by the lowest strength and excellent cold formability. Titanium Grade 1 is the softest commercially pure titanium grade. Due to its good formability, the mechanical values of this titanium are low. Titanium Grade 1 cannot be heat treated and is therefore often used for explosive cladding.

Product description Titaan Grade 1

Titanium Grade 1 is the softest unalloyed titanium grade with the lowest strength and highest formability.  This ensures that Titanium Grade 1 is highly weldable. It is resistant to slightly reducing conditions and can even be used very well in strongly oxidizing environments with or without chlorides. This alloy is used for various applications. Examples include heat exchangers, chemical equipment, chlorine production, desalination and anodes.

The protection mechanism is basically similar to that of stainless steel and aluminum. However, titanium oxide is more stable than aluminum and chromium oxides and is more compatible with the parent material. Grade 1 is purer which greatly improves cold formability. Titanium is less applicable in reducing environments, partly because oxygen is not present and partly because the passive skin dissociates in reducing media. Reducing media include hydrochloric acid, hydrogen fluoride, and oxalic acid. The following measures can be taken to improve corrosion resistance in these media: adding copper or iron ions to the medium, cathodic protection, or applying a palladium-alloyed titanium grade. Titanium can be machined and welded using conventional techniques. However, the specific properties of the material must be taken into account.
