Astm B677, N08925, N08926, N08904. Seamless pipes.

Are you interested in ASTM B677 and N08925, N08926, N08904, which deal with seamless pipes made from nickel alloys from the supplier AvecGlob? Here you will find interesting information on this topic.

General information

These standards and specifications cover seamless pipes manufactured by hot or cold rolling technology and conforming to the provisions of UNS N08925, N08354 and N08926 for use under normal corrosive conditions. Materials should be delivered in the usual, annealed conditions, or after heat treatment — quenching in water with subsequent cooling. The chemical composition of the material and its mechanical properties, as well as the results of hydrostatic tests and tests of non-destructive testing, must comply with the values contained in this specification and those specified in ASTM B677.

Application area

This standard relates to specifications N08925, N08926, N08904 relating to seamless cold and hot-deformed pipes. The general requirements for the specified products are given in specification B829.

Supplier — AvekGlob Company — offers at reasonable prices from the manufacturer seamless pipes from nickel alloys in a wide range of sizes, which are manufactured in accordance with the requirements of ASTM B677 and specifications N08925, N08926, N08904. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Special conditions of use

ASTM International adopted the definition according to which some grades of alloys, such as UNS N08904, are recognized as stainless steels. This is due to the increased percentage of iron in alloys. This conclusion is approved by the ASTM A01 committee and its subcommittees, therefore a number of provisions of the standard are now covered by the A269 and A312 / A312M specifications of the ASTM B677 standard.

Reference documents

When using the ASTM B677 standard and the specifications N08925, N08926, N08904, the following requirements must be taken into account:

Specifications A269 for seamless and welded austenitic stainless steel pipes intended for standard applications;

Specification A312 / A312M for seamless and welded austenitic stainless steel pipes with surface coatings;

Specification B829 for general requirements for nickel and nickel alloys. Seamless pipes;

E527 — the practice of marking metals and alloys in a unified numbering system UNS.

Supplier — AvekGlob Company — offers to purchase seamless pipes made of nickel alloys meeting ASTM B677 specifications and UNS N08925, N08354 and N08926 specifications. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
