Spring steel is a name given to a wide range of
steels[1] used in the manufacture of different products, including swords, saw blades, springs and many more. These steels are generally
low-alloymanganese,
medium-carbon steel or
high-carbon steel with a very high
yield strength. This allows objects made of
spring steel to return to their original shape despite significant deflection or twisting.
Many grades of steel can be hardened and tempered to increase elasticity and resist deformation; however, some steels are inherently more elastic than others:
Spring steel is commonly used in the manufacture of swords with rounded edges for training[12] or stage combat,[13] as well as sharpened swords for collectors and live combat.
Spring steel is one of the most popular materials used in the fabrication of
lockpicks due to its pliability and resilience.
Tubular spring steel is used in the landing gear of some small aircraft due to its ability to absorb the impact of landing.
It is frequently used in the making of
knives, machetes, and other edged tools.
