Home Alloy Steel 4340 Acero aleado 4340 Grade Summary: Alloy Steel 4340 can obtain much deeper harden-ability than 4100 series steel. High strength in heavy sections is possible with maximum toughness and ductility. This material has a high fatigue/tensile ratio and maintains strength, ductility, and toughness at relatively high temperatures. Also has excellent non-distorting properties for an alloy steel. Typical Applications: Crank shafts, axle shafts, dies, subs, gear shafts, gears, mine drilling parts, oil well fishing tools and parts, etc. Productos disponibles: Barra redonda Análisis químico típico: * C – .38/.43 Max. *Mn – .60/.90 *P – .035 Max. *S – .04 Max. *Si – .15/.35 *Cr – .70/.90 *Mo – .20/.30 *Ni – 1.65/2.00 Propiedades mecánicas típicas** Resistencia a la tracción (PSI) 110 000 Yield Point (PSI) 66,000 Elongation*** 23 Brinell Hardness 197 * Chemical Analysis will vary on each heat number ** Ranges shown are for 4340 Annealed- All values are minimum values and are representative. *** % in 2” Metal Supermarkets offers a variety of shapes and sizes of alloy steel, cut to the size you needCOMPRAR AHORA
