Titanium Grade 1 Plates | Lightweight Corrosion-Resistant Plates for Chemical, Oil & Gas, Marine, Pharma & Power
Table of Contents:
A coastal desalination plant was replacing 316L stainless tube sheets every three to four years because crevice corrosion and MIC pitting around the seawater inlets kept punching through, forcing emergency shutdowns and weld overlays that never quite lasted. When the EPC switched the critical tube sheets and channel covers to Titanium Grade 1 Plates (UNS R50250, 3.7024), the structure weight dropped by roughly 40% versus steel while the plant’s maintenance logs showed virtually no seawater‑side corrosion over the next service interval, allowing operators to stretch inspections and redirect budget from repair to expansion.
Titanium Grade 1 is a commercially pure titanium with the lowest strength but highest ductility and formability among the CP grades, combining a density less than 60% that of steel with excellent corrosion resistance in oxidising and seawater environments. It carries the UNS designation R50250 and EN number 3.7024, and plate products are commonly specified to ASTM B265, which defines chemical limits on interstitial elements such as oxygen (typically max ≈0.18%), nitrogen (≈0.03%), carbon (≈0.08%) and iron (≈0.2%) to maintain ductility and corrosion performance.
For procurement heads, engineers, fabricators, OEMs and hardware or industrial supply stores working in chemical, oil & gas, marine, pharma and power generation, Titanium Grade 1 plates provide an attractive alternative to 316L, 904L and some duplex stainless steels wherever corrosion resistance and weight saving matter more than very high strength. Compared with steels, Grade 1 titanium’s natural, self‑healing oxide film gives it excellent resistance to seawater, chlorides and many acids up to around 540 °C, and its low modulus and high ductility simplify forming of complex heat‑exchanger and vessel geometries.
Aurico Alloys LLP supports these needs as a trusted Titanium Grade 1 Plates supplier, manufacturer and stockist in India with export capability abroad, providing affordable, authentic plate with UNS R50250 / 3.7024 identity, ASTM B265 documentation and EN 10204 test certificates for global projects.

How Titanium Grade 1 Compares
| Alloy | Designation | Standards / Numbers | Key Characteristics |
|---|---|---|---|
| Titanium Grade 1 | CP Ti Grade 1 | UNS R50250, EN 3.7024, ASTM B265 Grade 1 | Lowest strength but highest ductility and formability among CP titanium; excellent corrosion resistance |
| Titanium Grade 2 (comparison) | CP Ti Grade 2 | UNS R50400 | Higher strength, slightly less formable; also widely used for chemical and marine service |
| Nimonic 75 (companion alloy) | High‑temperature Ni‑Cr alloy | UNS N06075, BS HR 203 for sheet/plate | Used for hot structural brackets and furnace parts where Titanium Grade 1 handles the corrosive but cooler zones |

Applications & Benefits
- Chemical & Oil & Gas: Titanium Grade 1 plates are widely used in reactors, heat exchangers, storage tanks and piping components where resistance to oxidising acids, chlorides and mixed media is critical, reducing corrosion allowance and inspection frequency compared with 316L and some duplex grades.
- Marine & Power Generation: In desalination plants, seawater‑cooled condensers, offshore platforms and seawater intake systems, Grade 1 titanium’s resistance to crevice corrosion and MIC in seawater significantly improves uptime versus stainless steel, with low density reducing support loads on structures and foundations.
- Pharma & High‑Purity Systems: Titanium plates provide clean, non‑contaminating surfaces with excellent corrosion resistance for WFI systems, clean‑in‑place circuits, and waste treatment where metallic contamination from steel corrosion products must be minimised.
