Titanium Grade 2 Plates | The Industrial Workhorse for Seawater & Chemical Corrosion Resistance
Table of Contents:
On a refinery’s seawater-cooled condenser line, 316L tube sheets and channel covers were lasting barely five years before crevice corrosion and MIC forced costly weld repairs and unplanned outages. After the plant upgraded those critical components to Titanium Grade 2 Plates (UNS R50400), inspection reports began showing essentially no measurable seawater-side corrosion, even though titanium plate weighs about 40% less than steel thanks to its low density, and the condenser has now run reliably through multiple turnarounds with only routine cleaning instead of heavy repair work.
Titanium Grade 2 is a commercially pure (CP) titanium with slightly higher oxygen and iron than Grade 1, giving it higher strength while retaining excellent ductility, weldability and corrosion resistance in oxidising, neutral and mildly reducing environments. It carries UNS designation R50400 and material number 3.7035, and is the most widely used CP titanium grade for industrial service because it balances a minimum yield strength of about 275 MPa (40 ksi) with outstanding resistance to seawater, moist chlorides, many acids, alkaline solutions and hot industrial gases.
For procurement heads, process and corrosion engineers, fabricators, OEMs and hardware or industrial supply stores in chemical, oil & gas, marine, pharma and power generation, Titanium Grade 2 plates provide a compelling alternative to 316L, 904L and even some duplex and nickel alloys wherever weight reduction, long life in seawater or chemicals, and compliance with NACE and pressure vessel codes are priorities. CP Grade 2 titanium’s strongly adherent oxide film gives it excellent resistance to general, pitting and crevice corrosion in natural and industrial waters, often surpassing stainless steels in such environments while operating continuously up to around 425–540 °C depending on service conditions.
Aurico Alloys LLP supports these requirements as an affordable, authentic Titanium Grade 2 Plates supplier, manufacturer and stockist in India with exports abroad, providing plate to UNS R50400 / 3.7035 chemistry and ASTM B265 mechanical requirements with EN 10204 test certificates for global projects.

Applications & Benefits
- Chemical & Oil & Gas: Titanium Grade 2 plates are used in heat exchangers, reactors, storage tanks and piping where oxidising acids, moist chlorides, chlorite/hypochlorite solutions, nitric and chromic acids, and many organic acids would attack stainless steels, with the protective titanium oxide film resisting both general and localised corrosion.
- Marine & Power Generation: In seawater-cooled condensers, desalination plants, offshore platforms and cooling-water systems, Grade 2’s excellent resistance to seawater and marine atmospheric corrosion combined with very good resistance to erosion and cavitation when properly designed gives far longer life than 316L or even super austenitic grades.
- Pharma & High-Purity Systems: Titanium Grade 2 plate is used for clean-in-place systems, waste treatment, and equipment where low metal ion release and smooth, corrosion-resistant surfaces reduce contamination risk, often outperforming stainless steels in oxidising media used in cleaning and sterilisation.
