ASTM A890 5A is a casting duplex stainless steel alloy known for its high strength and excellent corrosion resistance. It is designated as UNS J93404 or ACI CE3MN. Grade 5A has the nominal composition of 25Cr-7Ni-Mo-N, which is equivalent to Duplex 2507 (UNS S32750). ASTM A890 5A castings, either furnished in the product form of valve, bar or pump, are …

Definition, Characteristics & Applications According to ASTM B265, any product made of Grade 2 unalloyed titanium, 4.75 mm and under in thickness and less than 610 mm in width is classified as Grade 2 titanium strip. Since titanium strips are often furnished in coils, they are also called titanium coils in that case. Grade 2 unalloyed titanium is a typical …

Definition & Classification Titanium bars and billets generally refer to those made from unalloyed or commercially pure titanium Grade 1, Grade 2, Grade 3 and Grade 4 in accordance with ASTM B348 or its identical standard specification ASME SB-348. A titanium bar is a hot rolled, forged, extruded or cold worked semi-finished solid section product whose cross section area is …

Plates made of ASTM A240/ ASME SA-240 Type 316Ti is a typical molybdenum-bearing austenitic stainless steel stabilized with titanium. They are primarily used for pressure vessels and for general applications including architectural, building, construction, and aesthetic applications. Type 316Ti has the nominal composition of 16Cr-12Ni-2Mo-Ti with UNS designation S31635. Its European equivalent is EN 10028-7 1.4571/ X6CrNiMoTi17-12-2. Corrosion Resistance Type …

Material Grades, Classifications & Applications Flat-rolled products made from typical austenitic stainless steels ASTM A240 Types 304/304L and 316/316L can be classified as plates, sheets and strips. The UNS designation numbers of Type 304, 304L, 316, 316L are S30400, S30403, S31600, S31603, respectively. Type 304 stainless steel has the classic 18Cr-8Ni  nominal composition, which is the most common steel for …

Standard, Grades & Thicknesses Pressure vessel plates made of ASTM A204 (identical with ASME SA-204) steels are typical molybdenum-alloy steel plates intended particularly for welded boilers and other pressure vessels. The steel grades covered by ASTM A204/ ASME SA-204 are all carbon-molybdenum alloy steels with nominal composition of C-0.5Mo. Plates under this standard specification are available in three grades having …

ASTM A203/ A203, is the standard specification covers nickel-alloy steel paltes intended primarily for welded pressure vessels. These nickel alloy steels are mainly used for moderate- or low-temperature services. The nickel content added imparts significant improvements in fracture toughness and fatigue resistance of the steel. Plates under this specification are available with four strength levels and two nickel compositions:  Grade …

ASTM A537/ A537, is the standard specification covers heat-treated carbon-manganese-silicon steel plates. Carbon steel plates made in accordance with ASTM A537 are primarily intended for fusion welded pressure vessels and structures. Steel plates under this specification are available in three classes classified according to the different heat treatment: Class 1 (normalized), Class 2 (quenched and tempered) and Class 3 (quenched …

ASTM A516/ A516, identical with ASME SA-516/ SA-516M, is the standard specification for carbon steel pressure vessel plates for moderate- and lower-temperature services. Carbon steel plates made in accordance with ASTM A516 are primarily intended for service in welded pressure vessels where improved notch toughness is important. They can also be used for the manufacture of electric-fusion-welded steel pipes in …

ASTM A515/ A515M, identical with ASME SA-515/ SA-515M, is the standard specification for carbon-silicon steel plates primarily used for intermediate- and higher-temperature service in welded boilers and other pressure vessels. Hence, plates manufactured in accordance with ASTM A515, are also called as “intermediate-temperature pressure vessel plates” or “higher-temperature pressure vessel plates”. Plates under this specification are classified into three grades …

ASTM A36/A36M, identical with ASME SA-36/SA-36M, is the standard specification for carbon structural steel. This specification covers carbon steel shapes, plates, and bars of structural quality for use in riveted, bolted, or welded construction of bridges and buildings, and for general structural purposes. Structural products furnished under this specification shall conform to the general requirements of ASTM A6/A6M. When the …
