AISI 4140 Steel Bar, Steel Plate, Flats Supplier, Stockist et Exporter. AISI SAE 4140 mixtura chalybs est chromium molybdaeni mixturae specificatio late adhibita in generali proposito ferro distrahendo pro componentibus, sicut axes, spicula, tela, anni et alia applicationes. Similis gradus mixturae AISI 4130 chromae moly stannum chalybeum sed paulo superius carbonis contentum. Ferrum superior carbonis contentum AISI 4140 maiorem vim et calorem curationum facultates tribuit in comparatione ad ferrum AISI / ASTM 4130 mixturae, attamen naturas inferiores habet spontaneas.
