Modulus of Elasticity of Titanium Grade 2

Due to the high specific strength and excellent corrosion resistance, commercially pure titanium Grade 2 is considered for a wide range of industrial applications. Grade 2 titanium exhibits strong springback in cold forming process resulting from its much lower modulus of elasticity compared to steels. This particular elastic behavior shall be taken into account carefully. The modulus of elasticity (E), …

Commercially Pure Titanium | Unalloyed Titanium

Classification & Characteristics Commercially pure titanium is unalloyed titanium with small traces of impurities such as carbon, hydrogen, iron, nitrogen, and oxygen. It is classified into four ASTM grades: Grade 1, Grade 2, Grade 3 and Grade 4, which have varying amounts of impurities. The CP titanium generally has more than 1000 ppm oxygen and iron, nitrogen, carbon, and silicon …

ASTM A213 TP316L Seamless Tubes

Classification, Characteristics & Corrosion Resistance ASTM A213 Gr. TP316L seamless tubes can be further classified as TP316L boiler tubes, TP316L superheater tubes, and TP316L heat exchanger tubes, according to the service it is used for. The tubing is usually specified by outside diameter and minimum wall thickness, or average wall thickness. Sometimes the wall thicknesses are specified by Birmingham Wire …

Ternary Diagram for Wrought Austenitic Stainless Steels

Definition, Composition, Characteristics & Classifications Wrought austenitic stainless steels refer to austenitic stainless steels which have been processed by one or a combination of two or more wrought processes such as forging, rolling, upsetting, bending, extruding, pressing and drawing. After the wrought process, austenitic stainless steels develop and attain a fiber like grain structure aligned in the principal direction of …

ASTM A789 UNS S32760 Tubing

General Introduction The tubing made form ASTM A789 UNS S32760 is a super duplex stainless steel (SDSS) tube. UNS S32760 has guaranteed corrosion performance with the PREN value no less than 40. Similar to UNS S32750, it has excellent resistance to chloride stress corrosion cracking (SCC) and pitting corrosion; it also has much higher strength than the austenitic stainless steels …

Alloy 2507, UNS S32750 | Super Duplex Stainless Steel

General Introduction Alloy 2507, with UNS number S32750, is a famous super duplex stainless steel. As a member of the duplex stainless steel family, it is a two-phase alloy based on the iron-chromium-nickel system with a mixed structure of about equal proportions of austenite and ferrite. Due to the duplex phase balance, Alloy 2507 exhibits excellent resistance to general corrosion …

ASTM A182 Grade F51 is a standard duplex stainless steel with nominal composition of 22Cr–5Ni–3Mo–N. The ASTM A182 F51 forgings may be furnished as flanges, fittings, valve parts or other pressure vessel components. The ASME B31.3 process piping code has endorsed this steel as a listed material. The design minimum temperature for ASTM A182 F51 without impact testing is -60°F …

p/T Ratings for P250GH Flanges (EN 1092-1)

EN 1092-1 flanges, either made from EN 10273 P250GH hot rolled bars or EN 10222-2 P250GH forgings, are classified into material group 3E0. The pressure-temperature ratings (p/T ratings) for P250GH indicate the maximum allowable pressure (M.A.S in bar unit) at maximum allowable temperature (Temp. in °C unit) for various PN designations of P250GH flanges. The p/T ratings are dependent on …

P/T Ratings for P355QH1 Flanges

EN 1092-1 flanges made from P355QH1 forgings of EN 10222-4 can be furnished in PN designations from PN 2.5 through PN 400. EN 10222-4 P355QH1, with the steel number of 1.0571, is a weldable fine grain steel with high proof strength. It is categorized into flange material group 8E3 according to EN 1092-1. EN 10222-4 standard is specifying strength values …
