Internal metallurgical quality and consistency is also achieved by a meaningful reduction during the rolling process.

We have no amendments or corrections for this standard. SBQ steels are used for wind turbine components, bearings and seamless tubes.

These steels are produced both in cut lengths and coils. SBQ steels are at the higher end of the quality spectrum in both metallurgical consistency and dimensional accuracy. The term is used to describe steel long products for more demanding processing or end-use applications which cannot be met by merchant quality grades.

These steels are produced with more precise dimensions and chemistry. Special bar quality SBQ steels represents a wide variety of higher quality carbon and alloy steels. The internal quality of these steels is very important since machining and bending activities are involved during the processing of these steels in subsequent stages.

The petroleum industry uses them to produce valves and pipeline couplings for oil extraction. Most producers see ties to the automotive industry as the key drivers of the SBQ steel grades.

As the voice of the U. In the hand tools sector, they are used for hammers, screwdrivers and wrenches, among others. Proceed to Checkout Continue Shopping. These steels are generally machined, forged or cold drawn during subsequent processing. Standards Subsctiption may be the perfect solution. Similar is the case of resulfurized and rephosphorized steels. In order to achieve metallurgical quality, the steel has to be particularly clean.

The specification of SBQ steels may range from plain carbon and carbon manganese steels to alloy and stainless steels containing different percentages of aluminum, nickel, chrome and other alloying elements. Designed by Elegant Themes Powered by WordPress. The main application area for special bar quality steels is the automotive industry for engine, transmission, steering, suspension aa576 hydraulic components Fig 1.

ASTM standard A b covers specification for plain carbon special quality bar steels for applications which includes forging, heat treating, cold drawing, machining and many structural uses. Hot-wrought special quality carbon steel bars are produced in cut lengths and coils; the manufacturer should be consulted regarding sections and sizes available in coils, produced to a chemical composition. The products may also include hot rolled steel bars, cold finished steel bars.

These steels may have many grades. This specification has got 53 grades under the category of non-resulfurized steels, 15 grades under the category of resulfurized steels and 5 grades under rephosphorized and resulfurized category.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

The range of carbon content in these steels varies from grade to grade with minimum of 0. SBQ steels are used for bolts, springs, cable wires, chains, tyre beads and many similar applications in automotive industry. Some end uses of these steels may require superior surface quality, or special chemical restrictions, metallurgical characteristics, heat treatment awtm surface finishes.

This standard is not included in any packages. Subscription pricing 900b determined by: This standard is also available to be included in Standards Subscriptions.

Steel cleanliness can be achieved through the integrated route or through an additional refining step and cleaner iron bearing inputs into an EAF in a mini mill. If the document is revised or amended, you will be notified by email. Your Alert Profile lists the documents that will be monitored.
