Premium Material Specifications

• High-Carbon Steel: Top-quality springs are made from 65Mn (65 Manganese) spring steel or

• similar high-grade alloys. This steel offers an excellent balance of strength, toughness, and elasticity.

• Tempering (Heat Treatment): This is the most critical process. After being formed into shape, high-

• quality springs are properly heat-treated and tempered. This relieves internal stresses and gives the

• spring its "memory" – the ability to return to its original shape after repeated loading and unloading.

•  Poorly tempered springs will take a permanent set and sag quickly.

• Thicker Gauge (Lower Gauge Number): Higher quality often means a thicker, stronger wire.

  • Standard Quality: Often uses 3.5mm or 3.2mm wire.

  • High Quality: Frequently uses 3.0mm or even 2.8mm wire. A thicker wire provides greater support,

  • higher load capacity, and better resistance to sagging over decades of use.
