Strip steel has the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. Strip steel can be made of common carbon steel, carbon structural steel, spring steel, tool steel, stainless steel, etc. Strip steel is a kind of steel plate with thin thickness, narrow width and long length. The types of these alloy steel plates are named according to the composition of the alloying elements contained in the steel, so you can roughly understand their composition based on their names. The second type is chromium-nickel steel, the third is manganese steel, and the last type is silico-manganese steel.

The first is chromium steel, in which chromium is an important part of alloying elements. If divided according to the element composition of the alloy, the alloy steel plates can be divided into four types. alloy steel plates, which can be divided into different types according to different standards.

The values stated in each system are not exact equivalents therefore, each system must be used independently of the other. Within the text, the SI units are shown in brackets. However, unless the order specifies the applicable "M" specification designation (SI units), the material shall be furnished to inch-pound units.ġ.5 The values stated in either inch-pound units or SI are to be regarded separately as standard. These shall apply only when specified individually by the purchaser in the order.ġ.3 Specification A 266/A 266M covers other steel forgings and Specifications A 675/A 675M and A 696 cover other steel bars.ġ.4 This specification is expressed in both inch-pound units and SI units. Although this specification covers some piping components machined from rolled bar and seamless tubular products (see), it does not cover raw material produced in these product forms.ġ.2 Supplementary requirements are provided for use when additional testing or inspection is desired. Tubesheets and hollow cylindrical forgings for pressure vessel shells are not included within the scope of this specification. Larger forgings may be ordered to Specification A 266/A 266M. Forgings made to this specification are limited to a maximum weight of 10000 lb. Included are flanges, fittings, Valves, and similar parts ordered either to dimensions specified by the purchaser or to dimensional standards such as the MSS, ASME, and API specifications referenced in Section. Standard Specification for Carbon Steel Forgings for Piping Applicationsġ.1 This specification covers forged carbon steel piping components for ambient- and higher-temperature service in pressure systems.
