STERLER's unique heat-treatment technology gain the fined microstructure and high strength and toughness steel wire. Tensile strength of alloy steel can be customized up to 2000MPa.
Auto Eddy Current Test
Eddy Current Test for detects surface defects of wire and guarantee defects free quality wire.
| Wire Rod | Diameter (mm) | Tensile Strength | Norm Standard |
|---|---|---|---|
| SAE9254 (SWOSC-B) | 7.0mm~17.00mm | 1600MPa~2000MPa (can be customized) |
JIS G 3560 |
Raw material for steel products supplied by steel mill.
The first drawled is descailing to remove rust and scales on the surface of wire, and then draw down to roundness.
Use electromagnetic induction to detect and characterize surface and sub-surface defect in raw materials.
The second drawled wire is draw down to required diameter.
The induction — heating, quenched and tempered wires (ITW) with the diameter of 7～17mm show fine microstructure, fine austenite grains and less decarburization.
