SAE steel grades. The SAE steel grades system is a standard alloy numbering system (SAE J1086 - Numbering Metals and Alloys) for steel grades maintained by SAE International . In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels.
AISI 304L / UNS S30403 / DIN 1.4307 Low Carbon Austentic Stainless Steel Alloy 304L is an extra low carbon version of type 304 chrome-nickel austenitic alloy. It is typically used for welded applications that must resist intergranular corrosion. It is strong, light
El material 1.4307 es un acero austenítico al cromo-níquel. La tendencia a solidificarse se reduce debido al bajo contenido de carbono, lo que beneficia la maquinabilidad. Se proporciona una buena resistencia a la corrosión en medios ambientales naturales. Este acero inoxidable es resistente a la corrosión intergranular y es fácil de procesar.
