High Grade Gr4 Titanium Sheet — ASTM B265 Certified Industrial Titanium Sheet from PSX
Modern industrial construction projects, including chemical plant structures, offshore marine facilities, pressure vessel frameworks, and environmental protection engineering, are constantly challenged by high mechanical loads and harsh corrosive media. Carbon steel and ordinary stainless steel often fail prematurely under chloride, acid, and seawater corrosion, driving up maintenance and replacement costs year after year. For global procurement managers, Gr4 Titanium Sheet has become a revolutionary structural material that balances ultra-high tensile strength, outstanding anti-corrosion performance and lightweight properties. PSX’s high-grade Gr4 titanium sheet is redefining material selection standards for heavy-duty industrial construction worldwide.
Industrial high-purity Gr4 titanium sheet (Grade 4 / UNS R50700 / DIN 3.7065, Chinese TA4 grade) ranks as the highest-strength pure Titanium Material within the commercial pure titanium family. Our production strictly follows ASTM B265 specifications, adopting vacuum melting plus precision hot rolling and cold rolling production workflows. We tightly control interstitial elements such as oxygen, iron and hydrogen to eliminate hydrogen embrittlement risk and achieve stable batch-to-batch consistency.
Compared with Gr1 and Gr2 pure titanium sheets, PSX Gr4 titanium sheet delivers far higher tensile and yield strength while retaining titanium’s core advantages: acid & alkali resistance, seawater corrosion resistance, lightweight performance, good weldability and formability. It is the preferred titanium base material for high-load, high-corrosion industrial construction scenarios across chemical, offshore, environmental, pressure vessel and mechanical structural industries.
We provide full customization: custom sizing, surface finishing, laser cutting and slitting, plus free sample testing. Every batch comes with a formal Material Test Certificate (MTC), and we support third-party SGS inspection reports for export orders. We maintain long-term stable supply for factory manufacturers, OEM/ODM producers, distributors and global agents.
Gr4 titanium sheet has a density of only 4.51 g/cm³, just 60% of carbon steel. When applied to building frames, offshore platform components and pressure vessel structures, it delivers obvious weight reduction, lowers foundation load requirements and optimizes the overall structural design of industrial construction projects.
Reactor linings, heat exchanger plates, distillation columns, filtration components, acid-alkali pipeline equipment and electrolysis cell plates for new chemical industrial parks.
Seawater desalination facilities, seawater cooling systems, corrosion-resistant marine structural parts, subsea valve bodies and marine sampling equipment for coastal industrial construction.
Flue gas desulfurization and denitrification structures, electroplating workshop equipment, waste liquid treatment facilities and extraction tank linings for environmental engineering construction.
High-pressure anti-corrosion vessel linings, geothermal well equipment, and structural components for oil & gas corrosive well-site construction projects.
High-load anti-corrosion tooling, stamped titanium structural blanks and custom Titanium CNC Machining parts for mechanical workshop construction.
Important Note: PSX industrial-grade Gr4 titanium sheet complies with ASTM B265 for construction and industrial use only. Medical implant-grade Gr4 titanium must follow ASTM F67 with extra high-purity cleanroom production; industrial grade material cannot be used directly for human implantation.
PSX Material Selection Tip: Choose Gr2 titanium sheet for moderately corrosive construction environments to control costs; prioritize Gr4 Titanium Sheet for high-stress structural frameworks, pressurized vessel construction and high-load industrial building components.
Global industrial construction is shifting toward longer service life, lower life-cycle cost and lightweight structural design. Titanium sheet manufacturing technology keeps upgrading to match these construction trends. Manufacturers are now tightening control over interstitial elements (oxygen, hydrogen, iron) to achieve consistent mechanical performance across all production batches, avoiding property fluctuations that create risks for large-scale construction projects. Digital production tracking and batch traceability have become standard requirements for international engineering contractors. Meanwhile, integrated cutting, slitting and blanking services are increasingly popular; construction contractors prefer suppliers who can deliver prefabricated titanium blanks directly on-site to shorten construction cycles. PSX has kept pace with these trends by upgrading our rolling and precision cutting production lines, building full digital quality records, and providing one-stop pre-processing service for construction clients, greatly improving construction efficiency for global engineering projects.
Overseas factory procurement managers and engineering contractors focus strictly on five key factors when selecting titanium sheet suppliers for construction projects. First, strict compliance with international standards such as ASTM B265; they require complete material test certificates and full chemical & mechanical test data to pass project third-party auditing. Second, stable mechanical performance; construction structural parts cannot suffer strength deviation between batches, so buyers demand tight impurity control and consistent tensile/yield strength. Third, full traceability; every batch must be linked with heat numbers, inspection logs and batch records to meet construction engineering quality supervision requirements. Fourth, reliable delivery lead times; large industrial construction projects have fixed schedules, so suppliers must support both small trial sample orders and bulk full-plate bulk shipments without delays. Fifth, flexible technical support including custom cutting, surface treatment and drawing-based blanking; buyers avoid extra secondary processing costs after receiving raw sheets. PSX fully addresses all five concerns with standardized production, full batch inspection, export-ready documentation and flexible custom processing, making us a stable long-term supplier for construction material buyers across North America, Europe and the Middle East.
Titanium sheet R&D is now focused on thinner-gauge high-strength plate for lightweight industrial building frames, paired with tighter thickness flatness tolerance to reduce on-site machining work. New surface treatment technology improves the anti-corrosion stability of Gr4 titanium sheet under long-term outdoor atmospheric and marine chloride exposure, extending the service life of outdoor construction structures by 30% compared with traditional untreated Titanium plate . In addition, digitalized non-destructive testing (ultrasonic inspection) is widely adopted to detect internal plate defects before delivery, eliminating hidden structural safety hazards for pressure vessel construction. PSX’s technical team (including more than 10 professional engineers and 8 PhD-level specialists) continuously optimizes hot & cold rolling processes, develops high-precision blanking technology, and launches new prefabricated titanium structural blanks for modular industrial construction. We also develop matched Titanium Forging and Titanium Flange supporting parts to realize one-stop material supply for industrial construction projects.
The primary international standard governing Gr4 titanium sheet for industrial construction is ASTM B265, which specifies chemical composition, tensile mechanical properties, dimensional tolerances, surface quality and batch inspection rules for titanium sheet, strip and plate. All PSX Gr4 titanium sheets strictly follow this standard for production and testing. If buyers need medical-grade titanium materials for special projects, the material must comply with ASTM F67 with additional high-purity control and cleanroom production, which is completely separated from our industrial construction-grade production line. Before placing bulk orders, procurement managers should confirm the following technical clauses: material grade & standard, thickness & dimensional tolerance, surface finish, mechanical testing scope, optional ultrasonic flaw detection, and full MTC documentation requirements for project acceptance.
Founded in 2008, PSX (Baoji Pengshengxin Non-Ferrous Metal Co., Ltd.) is located in Baoji High-Tech Development Zone, known globally as China’s Titanium Valley. Our factory covers more than 5,000 square meters, equipped with complete vacuum melting furnaces, hot rolling mills, cold rolling lines, CNC cutting machines, shearing equipment and precision testing instruments.
