Stainless Steel Wire

详情

Stainless steel wire specifications vary by grade, gauge, and finish, with each type suited for specific environments and mechanical needs. The most common industrial standards are ASTM A**0 for general-purpose wire and ASTM A**3 for spring-tempered wire.
Common Grades and Their Uses

* Grade **4: The universal standard; non-magnetic and highly versatile with a tensile strength of approximately **1 MPa (*0 ksi).
* Grade **6: Known for superior chloride resistance, making it ideal for marine or chemical environments; typically has slightly lower tensile strength than **4.
* Grade **0: A ferritic, magnetic grade that is more affordable; often used for indoor decorative trims or appliances.
* Grade **0: High-carbon martensitic steel used for applications requiring extreme hardness (up to *0 HRC), such as cutlery or surgical tools.

Wire Gauges and Diameters
Diameter is the primary specification for wire, often measured in American Wire Gauge (AWG) or Standard Wire Gauge (SWG).

| Gauge (AWG) | Diameter (inches) | Diameter (mm) | Common Applications |
|**-|**-|**-|**-|
| *4 | 0.***0" | ~1.*3 mm | Heavy-duty food equipment, fencing |
| *8 | 0.***3" | ~1.*2 mm | Light-duty shelves, chicken wire |
| *4 | 0.***1" | ~0.*1 mm | Fine mesh, jewelry, precision springs |
| *0 | 0.***0" | ~0.*5 mm | Medical devices, fine filtration |

Mechanical Conditions & Finishes
Wire is typically supplied in one of the following mechanical conditions, which determines its flexibility and strength:

* Annealed (Soft): Most flexible; used for tying or weaving.
* 1/4 to 3/4 Hard: Intermediate strength and stiffness for general forming.
* Full Hard / Spring Temper: Highest tensile strength; used for springs and high-tension applications.
* Surface Finishes: Common options include Bright Annealed (BA) for high reflectivity, Matt (Dull) for industrial use, or Coated (e.g., soap or copper) to facilitate cold heading or drawing
