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

Within the limits of good manufacturing and inspection practices, the bars shall be free of injurious seams, laps, segregation, or other imperfections which are due to their nature, degree, or extent, will interfere with the use of the material in machining or fabrication of suitable parts. The tensile strength of the core is usually not affected since the nitriding temperature range is generally below the original tempering temperature employed.

This abstract is a brief summary of the referenced standard. The bars shall be free of pipe, cracks, and flakes. Bar applications include forging, heat treating, cold drawing, astm a322 and astm a322 structural components Note 1. Asgm hardened and tempered can be further surface hardened by flame or induction hardening and astm a322 nitriding. Historical Version astm a322 – view previous versions of standard.

However no warranty of accuracy, completeness or reliability is given, nor will any responsibility be taken for errors or omissions. Following forging operation the work piece should be cooled as slowly as possible. Parts can therefore be machined to near final size, leaving a grinding allowance only. Dark Blue Bar End. Welding of in whatever condition should always be carried out using astm a322 hydrogen electrodes – please consult your welding consumables supplier.

Astm a322 of in the hardened and tempered 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.

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

Following quenching to hand warm, most components should be tempered between Astm a322 – C to remove quenching astm a322 in the case. Hot-wrought alloy steel bars adtm produced in cut lengths and coils; the manufacturer should be consulted regarding sections and sizes available in coils, produced to a chemical composition.
