refer toTitanium PlateThe first thing many buyers think of is TA2.Titanium PlateIt's easy to ignore the 1.TA1 belongs to high-purity industrial titanium material, titanium purity is not less than 99.5%, impurity content control is lower.In medicine, food, electronic clean conditions, TA1 is often the preferred material.Shaanxi 100 Billion Tuoda Taking Root in Baoji Titanium Valley of China, Deep ploughing titanium non-standard products manufacturing 12 years, This article completely decomposes TA1Titanium PlateFour types of supply status, Seven media adaptation performances and five engineering real cases, Help technical and purchasing personnel distinguish working conditions, Decide when to choose TA1 instead of TA2Titanium Plate。

Core conclusion: TA1 is not a low-end substitute for TA2, but a high-purity titanium grade.Titanium purity ≥99.5%, material strength is low, but plasticity and toughness are outstanding.In medicine, food, electronics, cryogenic low temperature scenarios, TA1 comprehensive performance is better than TA2;However, limited by the strength index, TA2 is more suitable for high pressure and pressure conditions.Titanium Plate。

I. TA1 brand basic positioning

TA1 is a domestic titanium grade, corresponding to American standard UNS Grade1, Japanese standard JIS Class1, German standard DIN 3.7025,titanium plateThe system belongs to the highest purity and lowest strength brand.TA1 titanium content ≥99.5%, tensile strength not less than 240MPa, elongation after fracture ≥30%, mainly high purity and high toughness;TA2 titanium content ≥99.3%, tensile strength ≥345MPa, elongation ≥25%, is a general industry in the chemical fieldtitanium plate;TA9 added 0.15% palladium element, tensile strength ≥345MPa, elongation ≥25%, suitable for reducing acid corrosion environment;TA10 Add molybdenum nickel element, Tensile strength ≥485MPa, Elongation ≥18%, For severe corrosion conditions where crevice corrosion exists.

II. TA1titanium plateClass IV supply status M/Y/R/C

The first M annealing state is also the most common state of the project, hardness range 110-140HV, tensile strength 240-380MPa, elongation 30%-40%.Widely used in medical accessories, food processing plant, Chemical vessels and cryogenic equipment, stamping, bend, Excellent welding workability. second Y hot working state, Material strength enhancement, Hardness 140-180HV, Tensile strength 380-540MPa, Elongation 20%-30%, Mostly for structural parts, pressure-bearing shell, Cold working is possible, Annealing after machining is recommended to restore material toughness. The third R cold working state belongs to high strength state, hardness 180-220HV, tensile 540-700MPa, elongation 10%-15%, suitable for elastic elements, fasteners, spring products, this state is more sensitive to stress corrosion, concentrated alkali conditions are carefully selected. The fourth C solid solution state, Mostly used for specific high-end scenarios, Hardness 200-260HV, Tensile strength ≥700MPa, Common in aerospace structural components, high-strength connector, High procurement costs, Difficult to process, Chemical projects are rarely selected. Procurement model selection recommendations, most of the conditions preferred M annealing state;If the strength cannot be met, reassess Y or R status and review stress corrosion risk.

III. Reference for medium adaptation of Class 7

Dilute nitric acid concentration below 70%, TA1 Excellent corrosion resistance, Corrosion resistance is basically the same as TA2, Recommended TA1seawater, neutral saline water environment, TA1 Excellent corrosion resistance, Performance comparable to TA2, TA1 is optional.Under wet chlorine gas conditions, TA1 has good corrosion resistance, which is close to TA2, so TA10 is recommended for this condition;dilute sulphuric acid, TA1 corrosion resistance performance in dilute hydrochloric acid environment is general, TA2 is better., This kind of working condition takes priority to TA9Insufficient corrosion resistance under concentrated sodium hydroxide working condition TA1, TA2 is also resistant to corrosion, N6 nickel material is recommended for concentrated alkali environmentmedicine, Water for injection working condition TA1 high purity advantage outstanding, Better than TA2, TA1 is preferred for such scenariosFood, dairy production conditions, TA1 less impurities, no precipitation pollution risk, food items must TA1.

4, 5 real engineering application cases

Case 1, pharmaceutical factory freeze dryer tray, pharmaceutical high purity conditions.A vaccine manufacturer freeze dryer tray plate thickness of 3mm, medium for injection water, working conditions- 40℃ vacuum environment, TA 1M annealingtitanium plateNo choice for TA2.TA1 Purity ≥99.5%, Avoid metal ion precipitation pollution, High elongation in annealed state, Cryogenic environment will not crack, The equipment has been put into operation for 5 years and the working condition is stable., GMP inspection without defects. Case 2, Marine equipment seawater pipeline, anti-chloride ion erosion.Main pipeline thickness of island seawater desalination project 6mm, Medium sea water temperature 25 to 40 ° C, TA1 M Annealingtitanium plate。TA1 plastic is better, excellent weld toughness, 19000ppm chloride in seawater, Stress corrosion resistance is better than TA2, No pitting corrosion after 8 years of service, No leakage. Case 3, semiconductor ultrapure water tank, electronic high purity scene.12 inch wafer factory ultrapure water tank plate thickness 8mm, medium 18.2MΩ·cm ultrapure water, choose TA 1M annealed titanium plate, control TOC index less than 5ppb.TA1 iron, oxygen impurity content is low, prevent ultrapure water TOC rise, equipment operation for 3 years, TOC stable control in 1-3ppb range. Case 4, PTA plant acetic acid evaporator, material cost reduction transformation.PTA project acetic acid evaporator shell plate thickness 12mm, medium containing bromine ion acetic acid, temperature 120℃.TA9 titanium-palladium alloy was used in the original scheme., High procurement costs, TA1M annealed titanium plate with anode protection was selected after modification.Bromine ion concentration at site less than 100ppm, No need for TA9, Stable operation for 4 years after transformation, Single material cost savings of 35%. Case 5, liquid nitrogen cryogenic container, low-temperature toughness scenario.Liquid nitrogen tank plate thickness 10mm, Medium Liquid nitrogen- 196℃, TA1M annealed titanium plate was selected.TA1 has excellent low-temperature toughness and still maintains a high elongation at-196℃. The equipment has been used for 6 years without brittle fracture and leakage.

Five, TA1 processing five key process parameters

Forging temperature control in 850-950℃, TA1 forging window narrow, less than 850℃ forming difficult, more than 950℃ coarse grain affect properties;the anneal process adopt 550-600 DEG C and heat preservation for 1 - 2 hours, Heat preservation completed Air cooling, Annealing temperature lower than TA2Vacuum annealing is required after welding, TA1 residual stress after welding is greater than TA2, Heat preservation at 550-600℃ for 1-2h to relieve stressHF: HNO2 = 1:3, oxide film thinner, pickling time controlled within 5 minutes;Plate bending radius R≥2 times plate thickness T, TA1 material is soft, The bending strength is relatively low, Insufficient bend radius will result in outer arc cracking.

VI. TA1 procurement five-step pit avoidance points

Avoid Pit 1 and impersonate TA2 as TA1.The price difference between the two markets is not large, and some suppliers replace TA1 with TA2.Check MTC material list, TA1 iron content ≤0.15%, TA2 iron limit ≤0.30%. Pit Avoidance 2. Material certification does not mark iron element.For some MTCs, only titanium matrix and total impurities are indicated, and Fe is not listed separately.MTC is required to indicate Fe, O, N and H contents separately during procurement. Avoid pit 3, confusion of supply state, replace M annealed state with Y hot working state.Drawing requires M annealing, supplier delivers Y condition sheet.Check MTC mark annealing state, measured hardness ≤140HV, non-compliance can be rejected. Pit avoidance 4, negative deviation of plate thickness exceeds the standard.The drawing requires δ8mm, but the actual measurement is only 7.5 mm.Ultrasonic thickness measurement shall be adopted for sampling inspection one by one, and the tolerance shall be controlled ±0.3mm. Pit avoidance 5, UT flaw detection missed.There is a risk of undetected delamination defects in the titanium plate under pressure, Titanium plates for pressure equipment require 100% UT testing, Meet the AA qualification standard.
