The dissolved titanium ion Ti4+ has significant inhibiting effect on corrosion rate of unalloyed titanium in boiling nitric acid solutions. The tabulated values in below table show the corrosion rates of titanium (either Grade 1, 2, 3 or 4) with various titanium …

Unalloyed titanium (ASTM grade 1, 2, 3, 4) has been extensively used for handling and producing nitric acid in applications in which stainless steels have experienced significant uniform or intergranular attack. Titanium offers excellent resistance to HNO3 solutions over the …

ASTM A553, identical with ASME SA-553, is the standard specification covering 8% and 9% nickel alloy steel plates for use in the water quenched and tempered condition intended for the fabrication of welded pressure vessels, especially at low or cryogenic temperatures. …

Generally, stainless steel 304L can not be used in applications involving nitric acid since it may experience significant uniform or intergranular attack. Grade 2 titanium is applicable for handling and producing nitric acid. It shows excellent resistance to HNO3 attack …

Chromic acid is the aqueous solution of chromium trioxide (chromic anhydride) simply attained by dissolving CrO3 into water. The unalloyed titanium of ASTM grade 1, 2, 3, 4, 7, 16 can be used for applications involving chromic acid over a wide …

Titanium and its alloys are fully resistant to pure water, all nature waters, and stream to temperatures in excess of 315°C [600°F] since a firm passive titanium dioxide film will form which exhibits some surface discoloration at higher temperatures. When …

The heater for acetic acid processing is fabricated for a Peruvian client from Lima. The tube bundle of the heater is made of ASME SB-338 grade 2 titanium tubes (seamless) sized Φ19 mm x 2 mm(w.t) x 2638 mm(length). The tube sheet is …

The commercially pure titanium (unalloyed titanium) ASTM grades 1 to 4 can be used for applications involving acetic acid, or acetic acid combined with acetic anhydride, chlorine ion, or formic acid. The corrosion data for grade 1, grade 2, grade …

The yield strength values for grade 2 titanium seamless or welded tubes at temperature range from -20°F to 600°F are listed in below table: *Temp.: metal temperature, °F, not exceeding; *Y.S.: minimum yield strength at given temperature. *ASME SB-338 grade 2, …

The tensile strength values for grade 2 titanium seamless or welded tubes at temperatures ranging from -20°F to 600°F are listed in below table: *Temp.: metal temperature, °F, not exceeding; *T.S.: minimum tensile strength at given temperature. *ASME SB-338 grade …

Applicability and Temperature Limits Manufactured to ASTM B338(ASME SB-338), seamless and welded grade 2 titanium tubes can be used for condensers and heat exchangers. According to ASME Boilers and Pressure Vessel Code Section II Part D, they  are applicable for the …

Designated as UNS R50400, the ASTM Grade 2 titanium (commercially pure titanium) has several international equivalents which include DIN 3.7035 (German), GOST BTI-0 (Russian), BS 25-35t/in2 (British), JIS Class 2 (Japanese), Gr. TA2 (Chinese GB). Their chemical compositions and mechanical properties …
