What is 1080 Steel?

ASTM AISI 1080 steel is high carbon fully pearlitic steel having a carbon percentage between 0.75-0.88%. After heat treatment, this steel exhibits an optimum combination of elastic properties, high hardness, and low ductility.


Dimensions and tolerances
Thickness: 0.1 to 5 mm; Tolerances: +/- 0.008 to 0.11 mm
Width: 10 to 400 mm; Tolerances: +/- 0.15 to 0.60
*accept nonstandard size, please contact with our sales.


Our Advantage
1. Precise thickness, uniform hardness. Bright surface, smooth edge.
2. High flatness of board surface, high performance after multiple bending.
3. No cracking after stamping, and the quality is stable. And we provide Self-Inspection Reports and Raw-Material Test Certificates.
4. Professional anti-rust protective packaging. On time delivery, competitive price.
5. Large stock available, no MOQ requirement


1080 Cold Rolled Steel Strip Chemical Composition

1080 Cold Rolled Steel Strip Manufacture Condition:

1 The strip shall be furnished cold rolled spheroidized annealed, soft annealed, intermediate hardness, or full hard, as specified.

2 Intermediate hardness may be obtained by either rolling the strip after final annealing or by varying the annealing treatment, or both.

3 Pinch Pass一Spheroidized annealed and annealed material may be pinch rolled after the final anneal to improve flatness, uniformly oil, modify surface, obtain proper mechanical properties, and minimize stretcher strains if required by the purchaser.


1080 Cold Rolled Steel Strip Grain Size:

Unless otherwise specified, the steel strip shall be manufactured to a fine grain (austenitic and ferritic) practice.

Pearlite is the normal structure of cold rolled high- carbon strip unless it has had an intermediate anneal.


1080 Cold Rolled Steel Strip Decarburization:

1 When specified, the steel strip shall have a maximum permissible depth of complete plus partial decarburization of 0.001 in, [0.025 mm] or 1.5 % of the thickness of the strip, whichever is greater, except that strip less than 0.011 in. [0.279 mm] thick shall show no complete decarburization.

2 Annealed is mostly a spheroidized structure, but may contain some vestiges of pearlite.

3 Spheroidized annealed is essentially free of pearlite.

4 At least one specimen shall be taken froin each lot for microexami nation. The specimens shall be prepared for microscopic examination in accordance with Guide E3.


High carbon steel is an ideal material for custom flat springs, custom clips, and custom sheet metal stampings. High Carbon Steel Strips combines ease of fabrication with good strength and surface finish, is valued for its strength properties and operates at significantly higher levels than the mild steel grades. High carbon steel strip can be finished to meet the needs of a wide range of products. Where tensile strength and hardness are required, High Carbon steels are the material of choice. High Carbon Steel Strips Grades : C60, C65, C70, C75, C85, HC-14, En 42 J, C-98, C-100, C-124, HC21 etc. We offer spring steel strip in various shapes and sizes according to your final uses. These have excellent hardens property and high yield strength. Clients can avail these at competitive prices.


1080 Cold Rolled Steel Strip Finish

Cold-rolled carbon steel strip shall be supplied with the following finishes.

1 Number 1 or Matte (Dull) 一Finish without luster, produced by rolling on rolls roughened by mechanical or chemical means. This finish is especially suitable for lacquer or paint adhesion, and is beneficial in aiding drawing operations by reducing the contact friction between the die and the strip.

2 Number 2 (Regular Bright) Finish—Finish produced by rolling on rolls having a moderately smooth finish. It is less suitable that No. 1 (matte) finish for cold forming and may be applicable for certain types of plating.


It is furnished in the following types as specified:

1 Soft spheroidized annealed high-carbon steel is intended for applications requiring maximum cold forming. It is normally produced to give the lowest maximum Rockwell hardness for each grade.


2 Soft annealed high-carbon steel is intended for application requiring moderate cold forming. It is produced to a maximum Rockwell hardness.


3 Intermediate hardness high-carbon steel is intended for applications where cold forming is slight or a stiff, springy product is needed, or both. It is produced to specified Rockwell hardness ranges, the maximum being higher than obtained for the annealed type.


4 Full hard high-carbon steel is intended for flat application. It is produced to minimum Rockwell hardness requirements, which vary with grade, microstructure and gauge. Full hard can be produced with either a pearlitic or spheroidized microstructure or a mixture of both. The minimum hardness should be established between the consumer and the producer.


1080 Cold Rolled Steel Strip Ordering Information

Orders for material under this specification shall include the following information:

ASTM designation and date of issue.

Name, type, and steel grade number.

Hardness (if intermediate or restricted hardness is specified).

Decarburization (if required).



Coil size requirements.

Edge (indicate No. 1 round, square, and so forth).

Finish (indicate and specify).

Conditions (specify whether material is oiled or dry).

Package (bare coils, skid, and so forth).

Cast or heat (formerly ladle) analysis report (if required).


cold-rolled high-carbon strip in coils or cut lengths is classified as product that is 0.3000 in. [7.6 mm] or less in thickness and over 1/2 to 23 15/16 in. [12.5 to 600 mm] in width, inclusive. Strip tolerance products may be available in widths wider than 23 15/16 in. (600 mm) by agreement between purchaser and supplier; however, such products are technically classified as cold-rolled sheet. The maximum of the specified carbon range is over 0.25 to 1.35 %, inclusive.
