This abstract is a brief summary of the referenced standard. The steel shall be made by one or more of the astm a322 primary processes: Download this datasheet as pdf. Welding of in whatever condition astm a322 always be carried out using low hydrogen electrodes – please consult your welding consumables supplier.

4140 High Tensile Steel

Note 1 — A guide for the selection of steel bars is contained in Practice A Following quenching to hand warm, most components should be tempered between C – C to remove quenching stresses in the case. Bar applications include forging, heat treating, cold drawing, machining and many structural components Note 1. Immediately after hot forming, the bars shall be allowed to cool to a temperature below the critical range under suitable conditions to astm a322 imperfections caused by too rapid cooling.

Dark Blue Bar End. It is informational only and not an official part of the standard; the full text of astm a322 standard astm a322 must be referred to for its use and application. Link to Active This link will always route to the current Active version of the standard. The primary melting may incorporate separate degassing or refining and may be followed by secondary melting using electro-slag remelting or astm a322 arc remelting. Please consult your heat treater for best results. Parts can therefore be machined to near final size, leaving a grinding allowance only.

Welding of in the hardened and tempered condition as normally suppliedis not recommended astm a322 should be avoided if at all possible, as the mechanical properties will be altered within the weld heat affected zone.

Hot-wrought alloy steel bars are produced in cut lengths astm a322 coils; the manufacturer should be consulted regarding sections and sizes available in coils, produced to a chemical composition.

Where secondary remelting is employed, the heat shall be defined as all of the cast product remelted from a single primary astm a322.

Pre hardened and tempered can be further astm a322 hardened by flame or induction hardening and by nitriding. It is recommended that the work piece if possible is wrapped in an heat resistant blanket or buried in sand etc. This will have little effect on case hardness and will reduce the risk of grinding cracks.

The astm a322 shall be astm a322 as strand cast or ingot cast. Following forging operation the work piece should be cooled as slowly as possible. Chemical Composition Base Material.

However no warranty of accuracy, completeness or reliability is given, nor will any responsibility be astm a322 for errors or omissions. Within the limits of good manufacturing and inspection practices, the bars shall be free of astm a322 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 bars shall be free of pipe, cracks, and flakes.

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

This specification covers hot-wrought astm a322 steel bars. The tensile strength of the core is usually not affected since the nitriding temperature range is generally below the original tempering temperature employed.
