Recently we have supplied a French client with 220 pieces of titanium grade 2 seamless tube size of 19.05 mm(o.d)  x 1.25 mm(w.t) x 3000 mm (length). These commercially pure titanium tubes are manufactured to ASME SB-338 in annealed condition. According …

Titanium grade 2 is an unalloyed titanium which has small traces of carbon, oxygen, nitrogen, hydrogen and iron with UNS designation R50400. Titanium grade 7 is a typical titanium alloy consisting of unalloyed titanium plus  0.12% to 0.25% palladium with UNS …

Recently, Metals-Piping has supplied a nickel-copper alloy Monel 400 ring to a Korean client. The ring was forged to ASTM B564 UNS N04400 annealing heat treated and was delivered to an US client in Houston. Actual Chemical Composition & Mechanical Properties …

The modulus of elasticity of titanium grade 2 for at each given temperature is listed in below table: *Temp: metal temperature, °F; E: modulus of elasticity at given temperature, 106 psi.

Usually, titanium stub ends are used with ASME B16.5 carbon steel backing flanges (lap joint flanges) in pipeline to minimize the cost while maintaining excellent corrosion resistance to fluid. The stub ends may be furnished in short pattern or long …

Instantaneous Coefficient of Thermal Expansion *Coefficient A: the instantaneous coefficient of thermal expansion for 9% nickel steel at elevated temperatures, 10-6 mm/mm/°C. Mean Coefficient of Thermal Expansion *Coefficient B: the mean coefficient of thermal expansion for 9% nickel steel in going …

In order to investigate the fracture toughness of 9% nickel steel at low temperature, the specimen’s taken from Q+T pressure vessel plate of ASTM A553 Type I. Compact tension test was conducted on the test piece at subzero temperature -196°C. The …

Tensile tests were conducted on several 9% nickel steel specimens, which are manufactured in accordance with ASTM A353 or ASTM A553 Type I respectively. Typical tensile properties including tensile strength, yield strength, elongation, and reduction in area are presented in …

There are four grades of unalloyed titanium (commercially pure titanium): Grade 1, Grade 2, Grade 3, and Grade 4. The metallographic structure of all grades at room temperature is α phase (HCP). When the temperature is at about 885°C [1625°F], …

The unalloyed titanium refers to commercially pure titanium which has minimum titanium contents ranging from about 98.5 to 99.5 wt%. They are primarily used for corrosion-resistance applications as well as applications requiring high ductility for fabrication but relatively low strength …

Generally, 9% nickel steel pressure vessel plates may be furnished in double-normalized and tempered condition (ASTM A353), quenched and tempered condition (ASTM A553), or direct-quenched and tempered condition (ASTM A844). The microstructure of 9% nickel steel after heat treatment consist of …

General Introduction The 9% nickel steel is a low-carbon nickel alloy steel with nominal composition of 9Ni, which is particularly used for low-temperature or cryogenic pressure vessels and plants for processing, transportation, and storage of LNG down to -196°C [-320°F]. …
