A coastal power station had already upgraded its seawater intake and condenser tube sheets from 316L to Titanium Grade 2, yet high-velocity brine with entrained sand still caused worrying erosion corrosion at the inlets and weld transitions over successive shutdowns. When the asset team rebuilt the most highly stressed tube sheets and baffle plates in Titanium Grade 4 Plates (UNS R50700, 3.7065), they moved to the strongest of the commercially pure titanium grades minimum yield strength about 480 MPa, tensile strength around 550–580 MPa while keeping the same excellent resistance to seawater, brine and oxidising media, and inspection records over the next cycles showed stable wall thickness where stainless and even softer CP titanium had previously thinned.

A coastal power station had already upgraded its seawater intake and condenser tube sheets from 316L to Titanium Grade 2, yet high-velocity brine with entrained sand still caused worrying erosion corrosion at the inlets and weld transitions over successive shutdowns. When the asset team rebuilt the most highly stressed tube sheets and baffle plates in Titanium Grade 4 Plates (UNS R50700, 3.7065), they moved to the strongest of the commercially pure titanium grades minimum yield strength about 480 MPa, tensile strength around 550–580 MPa while keeping the same excellent resistance to seawater, brine and oxidising media, and inspection records over the next cycles showed stable wall thickness where stainless and even softer CP titanium had previously thinned.
Titanium Grade 4 is a commercially pure titanium with the highest oxygen and iron levels permitted among the CP grades, which increases its strength compared with Grades 1–3 while maintaining very good ductility, weldability and corrosion resistance. It is identified as UNS R50700 and material number 3.7065, and plate and sheet are typically specified to ASTM B265 / ASME SB‑265 Grade 4 and ASTM F67 for unalloyed titanium, with chemistry limits such as oxygen up to about 0.40%, iron up to 0.50%, nitrogen up to 0.05%, carbon up to 0.08% and hydrogen up to 0.015% by weight.
For procurement heads, corrosion and mechanical engineers, fabricators, OEMs and hardware or industrial supply stores in chemical, oil & gas, marine, pharma and power-generation sectors, Titanium Grade 4 plates provide a way to push design stresses higher than Grade 2 or 3 while still benefitting from CP titanium’s low density (less than 60% of steel) and superior resistance to brine, salt solutions, oxidising and alkaline media, organic acids and seawater. Typical data sheets quote minimum tensile strengths around 550–552 MPa, minimum yield strengths around 480 MPa and elongation at break of roughly 15–20%, giving a strength-to-weight ratio comparable to many stainless steels but with far better corrosion and corrosion-fatigue performance in seawater.

Applications & Benefits
- Chemical & Oil & Gas: Titanium Grade 4 plates are used in heat exchangers, reactors, pressure vessels, piping components and well equipment where high strength and very good resistance to oxidising acids, chlorides, brine and corrosive waste streams are needed, with corrosion-fatigue resistance that allows thinner sections than many steels.
- Marine & Power Generation: In seawater-cooled condensers, desalination plants, offshore structures and high-load marine machinery, Grade 4’s combination of strength comparable to many stainless steels and superior resistance to seawater and chlorine-containing media provides long life and structural weight reduction.
- Pharma & High-Purity Systems: Titanium Grade 4 plates support equipment where high mechanical strength, corrosion resistance and cleanliness are needed such as corrosive waste treatment vessels, heat exchangers and structural supports around high-purity circuits without the ion-release issues associated with corroding steel surfaces.
