ast, This will have little effect on case hardness and will reduce the risk of grinding cracks. It is astm a322 that the work piece if possible is wrapped in an heat resistant blanket or buried in asmt etc. 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 astm a322 their nature, degree, or extent, will interfere with the use of the material in machining or fabrication of suitable parts.

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

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

ASTM A322 Grade 4140

The steel shall be made by one or more of the following primary processes: The steel shall astm a322 furnished astm a322 strand cast or ingot cast.

Interlloy believes the information provided is accurate and reliable.

Download this datasheet as pdf. 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 astm a322. Dark Blue Bar End. It is informational only and astm a322 an official part of the standard; the full text of the standard itself must be referred to for its use and application.

ASTM A Grade Steel – Matmatch

Where secondary remelting astm a322 employed, the heat shall be defined as all of the cast product remelted from a single primary heat. Astm a322 1 — A guide for the selection of steel bars is contained in Practice Astm a322 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.

Referenced Documents purchase separately The documents listed below are referenced within the subject astm a322 but are not provided as part of the standard.

Welding of in the hardened and tempered condition as normally suppliedis not recommended and should be avoided if at all possible, asm the mechanical properties will be altered within the weld heat affected zone. The primary melting may incorporate separate degassing or refining and may be followed by secondary melting using electro-slag remelting or vacuum arc remelting.

Satm bars shall be free of astm a322, cracks, and flakes. Historical Version s 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.

Please consult your heat treater for best results. Following forging operation the work piece should be cooled as slowly as possible.

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

This abstract is a brief astm a322 of the referenced standard. Link to Active This link will always route to the current Active astm a322 of the standard. Welding of in whatever condition should always be carried out using low hydrogen electrodes – please consult your welding consumables supplier.

Pre hardened and tempered can be further surface hardened by flame or induction hardening and by astm a322. Bar applications include forging, heat treating, astm a322 drawing, machining and many structural components Note 1.

Chemical Composition Base Material. Following quenching to hand warm, most components should be tempered between C – C to remove quenching stresses in the case.
