| Commercially Pure Grade 1 | Excellent corrosion resistance and formability; commonly selected for chemical-processing equipment and low-strength fabricated parts. | ASTM B265; purchaser-specific chemical and mechanical requirements. | Material test report, heat number traceability, chemical analysis, tensile test results, dimensions and surface inspection records. | Confirm thickness, width, length, flatness, surface condition, and required temper before ordering. |
| Commercially Pure Grade 2 | A widely specified balance of corrosion resistance, weldability, and moderate strength for industrial applications. | ASTM B265; ASME SB-265 where code-approved material is required. | Certificate of conformity, chemical composition report, mechanical test report, heat and lot traceability. | Verify whether the purchase order requires ASTM, ASME, EN, or another regional designation; equivalents should not be assumed automatically. |
| Commercially Pure Grade 3 | Higher strength than Grades 1 and 2 while retaining strong corrosion resistance; suitable for more demanding industrial service. | ASTM B265; project or pressure-equipment specifications may add supplementary testing. | Heat-certified chemical analysis, tensile properties, dimensional report, visual and surface inspection results. | Check minimum tensile and yield properties for the specified thickness range and product condition. |
| Grade 5 Titanium Alloy | High strength-to-weight ratio for aerospace, medical, marine, and high-performance engineering applications. | ASTM B265; AMS 4911 or another approved aerospace material specification when specified by the design authority. | Aerospace material test report, heat treatment record, chemistry, tensile properties, hardness where required, and full traceability. | Confirm alpha-case limits, heat-treatment condition, thickness range, and any aerospace process approvals required by the end user. |
| Grade 7 Titanium Alloy | Palladium-alloyed titanium intended for enhanced corrosion resistance in severe chemical environments. | ASTM B265; application-specific corrosion and fabrication requirements. | Chemical composition report confirming palladium content, mechanical results, surface inspection, and heat traceability. | The buyer should validate corrosion compatibility with the actual process chemistry, temperature, and operating concentration. |
| Dimensional Accuracy | Thickness, width, length, squareness, flatness, and edge condition must conform to the purchase specification. | ASTM B265 dimensional tolerances, unless tighter project tolerances are agreed. | Inspection report showing calibrated measurement equipment, sampling plan, actual readings, and gauge identification. | Define measurement locations and allowable deviations before production; titanium sheet tolerances vary by thickness and product form. |
| Chemical Composition | Every heat should meet the specified limits for titanium, alloying elements, interstitial elements, and residual elements. | Applicable ASTM or AMS product specification; ASTM E2371 may be used for titanium-alloy chemical analysis. | Heat analysis, product analysis where required, laboratory method, and signed material test certificate. | Check oxygen, nitrogen, hydrogen, iron, aluminum, vanadium, palladium, and other elements relevant to the selected grade. |
| Tensile and Elongation Testing | Tensile strength, yield strength, and elongation must meet the grade and thickness-specific requirements. | ASTM E8/E8M for metallic tension testing; product specification controls the acceptance limits. | Test direction, specimen location, test temperature, results, laboratory identification, and calibration status. | Confirm longitudinal or transverse test orientation and whether testing is required per heat, lot, or shipment. |
| Hardness and Metallography | Hardness or microstructure evaluation may be required for heat-treated, aerospace, or critical-service material. | ASTM E18 or ASTM E384 where applicable; purchaser or aerospace specification may define metallographic criteria. | Hardness report, microstructure photographs or evaluation, heat-treatment records, and laboratory qualification information. | Hardness is supplementary unless explicitly required; it should not replace mandatory tensile testing. |
| Non-Destructive Examination | Ultrasonic, penetrant, or other examinations may be required to detect internal or surface discontinuities. | ASTM E2375 for ultrasonic examination of wrought products; acceptance class must be stated by the buyer. | NDT procedure, operator qualification, equipment calibration, scan coverage, indications map, and final acceptance record. | Do not accept “100% tested” without the test method, sensitivity, coverage, and rejection criteria. |
| Surface Quality | Material should be free from harmful cracks, laps, seams, excessive scale, embedded contamination, and unacceptable scratches. | ASTM B265 surface requirements and purchaser-approved visual acceptance criteria. | Visual inspection report, surface-finish designation, photographs where required, and repair or rework records. | Specify mill finish, pickled finish, polished finish, roughness limit, and allowable imperfections in writing. |
| Quality Management Certification | A documented quality system should control production, inspection, nonconformities, corrective actions, and records. | ISO 9001; AS9100 for aerospace supply chains where applicable. | Current certificate, certification scope, issuing body, validity dates, and audit status. | The certificate scope should cover titanium sheet manufacturing, processing, testing, or distribution as relevant to the order. |
| Testing Laboratory Competence | Critical test results should come from a competent internal or independent laboratory using validated methods. | ISO/IEC 17025 for testing and calibration laboratory competence. | Laboratory accreditation scope, test method, uncertainty information where relevant, and calibration records. | Verify that the accreditation scope covers the exact test performed rather than relying only on a general accreditation statement. |
| Material Certification and Traceability | Each sheet, bundle, or lot should remain traceable to the original heat, processing route, inspection results, and shipment documents. | EN 10204 Type 3.1 or 3.2 documentation where contractually required; applicable ASTM or AMS requirements. | Material test certificate, heat number, lot number, permanent or attached marking, packing list, and certificate of conformity. | Ensure markings remain legible after cutting, slitting, or repacking and that partial sheets retain original traceability. |
| Export and Packaging Controls | Packaging must prevent moisture, salt contamination, abrasion, edge damage, and loss of identification during international transport. | Contract packaging specification, destination-country import rules, and agreed logistics requirements. | Packing photographs, package dimensions and weight, shipment labels, documentation list, and inspection-before-shipment record. | Agree on corrosion protection, separators, lifting points, pallet strength, moisture barriers, and document placement before dispatch. |
