Titan Wallet & TerraSteel Seed Phrase Backups by PlebStyle
In 2023, the German engineers of the company PlebStyle developed two new seed phrase backups made of alloying steel with the addition of titanium: Titan Wallet and TerraSteel.
The combination of titanium alloyed stainless steel 316ti and exceptionally durable titanium (Grade 5) provides the best protection for your Bitcoin - and that includes all relevant material properties.
Thicker material, especially in the protective case, literally provides an extra layer of protection for your Bitcoin backup.
PlebStyle Product Line
The material combination of Titanium-Alloyed Stainless Steel 316ti and Titanium Grade 5 ensures exceptionally secure storage. This innovative fusion not only provides the highest resistance but also ensures first-class security for your valuable seeds.
The little brother of the Titan Wallet is 10 mm shorter and entirely crafted from 316 stainless steel (V4A). Its excellent material properties make it a reliable companion, especially in outdoor environments.

Titan Wallet & TerraSteel by PlebStyle: The protective shield for your Bitcoin seed phrase
Stamp your seed into our metal backup and protect yourself from:
- Natural disasters
Fires, Water, Corrosion - Accidents
Extreme forces, Acids - Attackers
Hackers, Thieves
Standard for others, taboo for us: Stainless Steel 304 and Titanium Grade 2
In four chapters we show you which material is really suitable!
- Yield Strength Rp and Rp0.2
- How strong is the Titan?
- Nightmare house fire
- Corrosion resistance
Knowledge: The Yield Strength Rp
STRESS-STRAIN-DIAGRAM
The Stress-Strain-Diagram shows the strain (ε) of the material on the x-axis, while the y-axis represents the stress (σ) applied to the material.
The value Rp is also known as the Yield Strength. Rp is defined as the point at which plastic deformation begins. Thus, Rp indicates the stress (= force per area) required to produce permanent deformation in the material.
Rp is an indicator of the material's ability to withstand stress without permanent deformation. A higher Rp value means that the material is more resistant to deformation and has greater strength.
Permanent deformation would destroy the Steel Wallet.
Rp0.2 = central material characteristic
STRESS-STRAIN-DIAGRAM - SIMPLIFIED
Rp0.2 is a standard value in materials science and is available for (almost) every material.
When determining Rp0.2, the stress is measured at a specific point on the stress-strain curve, precisely at a plastic deformation (=strain) of 0.2%.
Rp0.2 is ultimately easier to determine than Rp, which is why the latter is used as a reference value in science.
Structure & Material
BITCOIN MEETS GERMAN ENGINEERING
The two-part design (outer and inner housing) and the choice of materials are designed for the safety of your seed.
The base body and seed discs are made of AISI 316Ti (Titanium Alloy Stainless Steel, 1.4571) for optimal protection.
The inner housing is 100% titanium grade 5 (3.7165). It serves as a second, extremely strong protective shield for your seed.
Quality instead of Marketing
COMPARISON OF RP0.2 OF VARIOUS MATERIALS
With other steel wallets and backup solutions, you regularly read woolly marketing slogans like "finest stainless steel" or "high-quality titanium". The actual material used is usually well hidden or not even mentioned.
Sad but true, the "finest stainless steel" is often just a standard AISI 304 (1.4301) stainless steel. Titanium is usually Grade 2 (3.7035). With titanium, the choice of this weaker variant is obvious, since you would have to use more than 4 times the force to hammer your seed into titanium Grade 5 (compared to the stainless steels AISI 304, 316 or 316Ti). At most, Roman Reher can manage that...
Stainless steel: 316Ti is the clear favorite
316Ti stainless steel has been specially developed to maintain high strength at high temperatures. The titanium carbides in this stainless steel make it possible.
Unfortunately, the vast majority of steel wallets and backup solutions are made of 304 stainless steel ...
Titanium Grade 5 is undisputed
A graphic says more than 1000 words. Thanks to additives (=alloys) such as alumiunium and vanadium, this material has excellent properties.
Since Titanium Grade 2 is much cheaper, this material is often used. But not in our case!
Fun Fact: Titanium Grade 5 was originally developed for aerospace applications.
Titan Wallet: Very Good to Excellent!
RESISTANCE TO CORROSION AND ACID
Titanium has excellent resistance to corrosion and acids and is one of the few materials considered resistant to seawater.
AISI 304 is largely adequate for normal use.
304 is sensitive to chlorides and acids and is also somewhat susceptible in saline media.
Steels 316 and 316Ti are less sensitive in this respect. For example, they are even resistant to sulfuric acid (1%).
PREN = Pitting Resistance Equivalent Number.
