Titanium Grade 2 is a high-strength, corrosion-resistant industrial metal widely used across chemical processing, marine environments, and aerospace. Employed in Titanium Grade 2 sheet, plate, and tubing, this clean titanium alloy balances toughness, formability, and weldability. Engineers choose Titanium Grade 2 for robust applications that require long-term resilience against harsh conditions.
Chemical Composition
Contains over 99% titanium with minimal impurities—iron (≤0.3%), oxygen (≤0.25%), and carbon (≤0.1%)—which ensures purity and corrosion resistance.
Mechanical Properties
Tensile strength: ~350 MPa
Yield strength: ~275 MPa
Elongation: ≥20%
Corrosion Resistance
The passive oxide layer offers excellent resistance to seawater, chlorine, and organic acids. Independent Grade 2 corrosion resistance testing shows minimal weight loss even after prolonged exposure, making it ideal for aggressive environments.
Heat Resistance
Performing effectively up to 400 °C, though for higher-temperature use, alloyed grades may be recommended.
Flat, thin, and flexible—perfect for sheet metal fabrication, chemical tank lining, and instrumentation panels. You can buy Titanium Grade 2 sheet online from major U.S. suppliers.
Thick, rigid, and load-bearing. Frequently used in pressure vessel flanges and structural components. The titanium grade 2 plate price per kg is typically lower than Grade 5, thanks to simpler alloying and processing.
Offers high strength-to-weight ratio—essential for aerospace frames, heat exchangers, and marine piping. Standard tubing is seamless with tight tolerance and excellent weldability.
| Feature | Grade 2 | Grade 5 |
|---|---|---|
| Tensile Strength | ~350 MPa | ~895 MPa |
| Corrosion Resistance | Very high | High, but lower than 2 |
| Weldability | Excellent | Good |
| Cost | Lower | Higher due to alloying |
When comparing Titanium Grade 2 vs Grade 5, Grade 2 is preferred for corrosion-critical applications where extreme strength is less important.
Aerospace: used in fuel lines, heat exchangers, and fasteners.
Chemical Processing: ideal for tanks and piping in chlorinated or acidic environments.
Marine Engineering: valves, shafts, and fittings remain intact in seawater.

Best practices for Grade 2 welding techniques include:
Use TIG welding with pure argon shielding.
Maintain clean, oxygen-free environment near welds.
Post-weld heat treatment and pickling to remove oxidation.
For cutting and forming, avoid overheating; use cryogenic nitrogen cooling if necessary to retain mechanical properties.
You can buy Titanium Grade 2 sheet online from reputable U.S. suppliers such as:
Always verify certifications (AMS 4928, ASTM B265) and mill traceability before purchase. For value, consider global stockroom networks with domestic shipping.
As of mid‑2025, Titanium Grade 2 plate price per kg ranges from $25–$30 depending on thickness and order size. Price factors include raw titanium cost, energy prices, alloying tech, and supplier margins.
Titanium Grade 2 delivers high corrosion resistance, good strength, and excellent weldability—ideal for industries that demand durability in harsh environments. Choose Grade 2 for sheet, plate, or tubing when corrosion protection outweighs ultra-high strength needs.
Q1: Is Titanium Grade 2 stronger than Grade 5?
A: No. Grade 5 has nearly 2.5× higher tensile strength but is less corrosion‑resistant.
Q2: Can you weld Grade 2?
A: Yes—TIG welding with pure argon works best for clean, durable joints.
Q3: Where to buy Titanium Grade 2 sheet in the USA?
A: Check suppliers like TitaniumSuppliesUSA, IndustrialMetalsDirect, and AeroMetalCo.
Q4: Does Titanium Grade 2 rust?
A: No—its oxide layer makes it virtually immune to rust in most environments.
Q5: Can it be used in seawater?
A: Absolutely—Grade 2 is marine-grade titanium, widely used in seawater applications.
