What is SAE 1080 high carbon steel wire rod?
SAE 1080 is an approximately 0.8% carbon plain steel grade (UNS G10800), often supplied as hot-rolled wire rod coils for further high-carbon wire processing.
What is the carbon content of SAE 1080?
The published reference range is 0.75–0.88% C with approximately 0.60–0.90% Mn. The contractual SAE J403 version and mill heat-analysis report govern the order.
Which specifications apply to SAE 1080 wire rod?
SAE J403:2024 is a chemistry grade reference. ASTM A510/A510M-25 provides general wire rod requirements if included in the purchase order. ISO 16120-4:2017 may be considered for a separately agreed special wire rod specification.
What diameters of 1080 wire rod can be requested?
Common enquiries include Ø5.5, 6, 6.5, 7, 8, 9, 10, 12, 14 and 16 mm; the actual rolling program and tolerance must be confirmed by the mill.
Is SAE 1080 wire rod the same as spring wire?
No. This page concerns hot-rolled rod feedstock. Finished spring wire requires additional drawing or heat treatment, a finished-wire specification and appropriate inspection.
Why is controlled cooling important for high-carbon rod?
Cooling history affects the pearlitic structure and the rod tensile/drawing condition. A specific structure or property range must be contracted and verified.
Does SAE 1080 guarantee a tensile strength or hardness?
The SAE grade alone defines chemistry; incoming rod tensile values depend on diameter and rolling/cooling condition. Specify the required range and test method when needed.
What is surface decarburization?
It is a local reduction in carbon content near the steel surface caused by processing conditions. For certain drawn and fatigue-loaded products, agree allowable depth and test method.
Can SAE 1080 replace 82B high-carbon wire rod?
Not automatically. Chemistry, residual elements, drawing structure, cooling practice and the approved downstream specification must be checked before any substitution.
Can SAE 1080 wire rod be used for prestressing strand?
An appropriate high-carbon rod may be evaluated as raw material, but finished prestressing strand must independently meet the specified strand standard, production process and certifications.
How do you estimate coil shipment tonnage?
Multiply the buyer-confirmed nominal mass per coil by the number of coils. A separate theoretical kg/m calculation can estimate mass from rod diameter and running length.
What details are needed to quote SAE 1080 wire rod?
Send diameter, total tonnage, nominal coil weight, grade/standard edition, surface/decarburization limits, downstream drawing use, test documents and shipment destination.
