What Material Is Used For Leaf Springs

Trailer leaf springs are commonly made from high-carbon steel alloys due to their excellent strength, durability, and resistance to fatigue. Some of the specific materials used for trailer leaf springs include:

1.65Mn (Mn65) - A high-carbon steel known for its toughness and wear resistance.

2.SUP9 - A silicon-manganese steel with good elasticity and hardness.

3.5160 - An alloy steel containing chromium, providing excellent toughness and durability.

5.SAE 1095 - A high-carbon steel with high hardness and fatigue resistance.

These materials are chosen to withstand the heavy loads and constant flexing that trailer leaf springs experience.
