Introduction

COMMONLY STOCKED ANNEALED SPRING STEEL

AISI 1050

Our AISI 1050 annealed spring steel is the most cost-effective option. It can be heat-treated for additional hardness and is easily formed. Out of our available spring steels, AISI 1050 has the lowest carbon content.

AISI 1074 AND 1075 SPRING STEEL

We offer both AISI 1074 and AISI 1075 annealed spring steel. Our 1074/1075 spring steel is spheroidized for greater formability and features medium carbon content.

AISI 1095 SPRING STEEL  

Mead Metals’ AISI 1095 delivers the greatest fatigue values and elasticity of any of our available annealed spring steels. AISI 1095 offers the best quality of all of our annealed spring steels and features the highest carbon content.

Ordering

Minimum Order Quantities

Our Minimum Order Quantities enable us to suit metal product orders of all sizes. Every metal product we provide has its own MOQ, and for annealed spring steel, our MOQ is 30-60 lbs. While we can, and will, support orders for quantities smaller than this, the minimum lot charge will remain the same for any quantities ordered at, or below, a metal’s MOQ. Additional variables apply, depending on material thickness, width, and additional processing.

Production Process

740x455_0008_Annealed
1

Steel is heated to its ideal temperature

2

Ideal temperature is maintained for a predetermined amount of time before the material is cooled slowly

3

The annealing process reduces material hardness & increases electrical conductivity

Pros/Cons

PROS:

  • Versatile 
  • Cost-effective
  • Pliable 
  • Easily formable 
  • Machinable 
  • Resistant to cracking
  • Often largely available in the marketplace
