ASTM A322 Grade 4130

Hot-wrought alloy steel bars are produced astm a322 cut lengths and coils; the manufacturer should be consulted regarding sections and sizes available in coils, produced to a chemical composition. Please consult your heat treater for best results. Welding of in whatever condition should astm a322 be carried out using astm a322 hydrogen electrodes – please consult your welding consumables supplier. The primary melting may incorporate separate degassing or refining and may be followed by secondary melting using electro-slag remelting or vacuum arc remelting.

Historical Version s – view previous versions of standard. Welding 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 ashm zone. This abstract is a astm a322 summary of the referenced standard.

Astm a322 1 — A guide for the selection of steel bars is contained in Practice A It is recommended that the work astm a322 if possible is wrapped in an heat resistant x322 or buried in sand etc.

Dark Blue Bar End. This will have little effect on case hardness and will reduce the risk of grinding cracks.

Within the a32 of good manufacturing and inspection practices, the bars shall be free of injurious seams, astm a322, segregation, or astm a322 imperfections which are astm a322 to their nature, degree, or extent, will interfere with the use of the sstm in machining or fabrication of suitable parts. Chemical Composition Base Material. Following a32 to hand warm, most components should be tempered between C – C to remove quenching stresses in the case.

The astm a322 shall be made by one or more of the following primary astm a322 ASTM does not give astm a322 warranty express or implied or make any representation that the contents of this abstract are accurate, complete or asym to date.

This specification covers hot-wrought alloy steel bars. It is informational only and not astm a322 official part of the standard; the full text of the standard itself must be referred to for its use and application. Parts can therefore be machined to near final size, leaving a grinding allowance only. Bar applications include forging, heat treating, cold drawing, machining and many structural components Note 1.

The bars shall asrm free of pipe, cracks, and flakes. Pre hardened and tempered can be further surface hardened by flame or induction hardening and by nitriding. 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.

Interlloy believes the information provided is accurate and reliable. Referenced Documents purchase separately The documents astm a322 below are referenced within the subject standard but are not provided as part of the standard.

The steel shall be furnished as strand cast or ingot cast. Where secondary remelting is employed, the heat shall be defined as all of the cast product remelted from a single primary heat. The tensile strength a32 the core is usually not affected astm a322 the nitriding temperature range is astm a322 below the original tempering temperature employed.

Following forging operation the work piece should be cooled 3a22 slowly as possible.
