Alloy Plate - 4140 / 4340 / 8620 - ASTM A 829 Standard specification for Alloy Steel Plate Furnished to Chemical Composition Requirements. ASTM A 829 was first issued in 1984; prior to that these grades were defined by AISI specifications. Alloy Plate Plates Manufacturer and Exporter - Reliable Oliver Steel offers these chemistry-only alloy plate grades in the three most commonly used chemistries. 4140 is the standard for medium carbon chromium-molybdenum alloy with excellent response to quench-and-temper and moderate through hardening capabilities; at Oliver, our 4140 is modified to include a small amount of vanadium for even better hardening. 4340 includes nickel for higher overall hardness

Jan 01, 1993 · ASTM A709 (2010a) specification covers carbon and high-strength, low-alloy steel structural shapes, plates, and bars and quenched and tempered alloy steel for structural plates intended for use in bridges. Seven grades are available in Industrial-Grade steel plate sae 4340.. for Specialists Most of the steel plate sae 4340.. are malleable and have low density, which gives designers, engineers, contractors, and metal molding specialists the flexibility to create multiple custom solutions. The steel plate sae 4340.. have a low weight-to-thickness ratio, so they are easy to transport and work with. They can be stacked to ease the shipping burden and keep transportation costs down.

Generally any welding process other than oxy-acetylene welding can be used with high alloy materials. The welding process should be chosen to give the best deposition rate that will also achieve the properties required. Consideration should be given to metallurgical or structural properties and SAE AISI 4340 Steel Properties, Heat Treatment, Equivalent Since 4340 alloy steel is air hardened, the welded parts should be either annealed or normalized and tempered shortly after welding. The high hardness of 4340 alloy steel requires that the material be welded in the annealed or tempered state and then heat treated to resist martensite formation and cold cracking. However, as in motor shaft applications, under quenching and tempering conditions, 4340
