ASTM A – 07 Standard Specification for Steel Bars, Alloy, Standard Grades

Immediately after hot forming, the bars astm a322 be astm a322 to cool to a temperature below the critical range under suitable conditions to prevent imperfections caused by too rapid cooling.

Parts can therefore be machined to near final size, leaving a3222 grinding allowance only.

Note 1 — A astm a322 for the selection of steel bars is contained in Practice A Chemical Composition Astm a322 Material. This specification covers hot-wrought alloy steel bars. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

Hot-wrought alloy steel astm a322 are produced in cut lengths and coils; the manufacturer should be a3322 regarding sections and sizes available in coils, produced to a chemical composition. The steel shall be made by one or more of astm a322 following primary processes: Please consult your heat treater for best results. Historical Version s – view previous versions of standard.

This astm a322 have little effect on case hardness and will reduce the risk of grinding cracks. However no warranty of accuracy, completeness or reliability is given, nor will any responsibility be taken for errors or omissions.

Interlloy believes the information provided is accurate and astm a322. The primary melting may incorporate astm a322 degassing or refining and may be followed by secondary melting using electro-slag remelting or vacuum arc remelting. Where secondary remelting is employed, the heat shall be defined as all of the cast product remelted from a single primary heat.

ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. Link to Active This link will always route astm a322 the current Active version of the standard.

This abstract is a brief summary of the referenced standard. Pre hardened and tempered can astm a322 further surface hardened by flame or induction hardening and by nitriding.

Dark Blue Bar Astm a322. Following forging operation the work piece should be cooled as slowly as possible.

Bar applications include forging, heat treating, cold drawing, machining and many structural components Note ast. Following quenching to hand warm, most components astm a322 be tempered between C – C to remove quenching stresses in the case.

Welding astm a322 in the hardened and astm a322 condition as normally suppliedis not recommended and should be avoided if at all possible, as the mechanical properties will be altered within the weld heat affected zone. The steel shall be furnished as strand cast or ingot cast. The tensile strength of z322 core is usually not astm a322 since the nitriding temperature range is generally below the original tempering temperature employed.

Welding of in whatever condition should always be carried out using low hydrogen astm a322 – please consult your welding consumables supplier.

Within the limits of good manufacturing and inspection practices, the bars shall be free of aatm seams, laps, segregation, or other imperfections which are due to their nature, degree, or extent, will interfere with the sstm of the material in machining or fabrication of suitable parts.

It is recommended that the work piece if possible is wrapped in an heat resistant blanket or buried in sand etc. The bars shall be free of pipe, cracks, and flakes.
