ASTM A684 1074 Cold Rolled Steel Strip

1074 Carbon steels are designated by AISI four-digit numbers. They contain only carbon as the major alloying element. 1.2% of manganese, and 0.4% of silicon are present in these steels. They also contain chromium, nickel, copper, aluminium, and molybdenum in small amount. Impurities such as sulfur and phosphorous are also found in these steels.

1074 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.
The surface finish of Hardened and Tempered Steel Strip products is not too critical in general engineering applications where the normal blue-black (also known as blue-grey) oxidized finish from the heat treatment is satisfactory. By control of the atmospheres in the furnaces non-oxidised surfaces can also be produced, on a selected basis, and alternatively, steels can be satin or bright polished were needed, these finishes being as much for cosmetic reasons as for engineering purposes.
We hold expertise in providing a qualitative range of Blue Tempered Steel Strips to our clients at affordable prices. Owing to features like high efficiency, optimum performance and durable finish standards they are highly demanded in the market. Our ranges of these are used in various industries like automobile, cable and electronic industries. Clients can avail these strips in various dimensions with thickness as per their own requirement. We supply these at market leading prices. Known for its durability and rigidity, blue spring steel is often used in the production of clips, blades/knives, springs, coiled springs, washers, saw blades, trowels, scrapers, doctor blades for pulp mill & printing applications, spring clamps, antennas, lock picks, clock hands, grass/grain cutting tools, and brake discs.
1074 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.
1074 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.
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.
1074 Cold Rolled Steel Strip Finish
Surface—The strip shall be furnished with a No. 2 Regular Bright or No. 1 Matte (Dull) finish, as specified.
Oiling—The strip shall be furnished oiled or dry, as specified.
1074 Cold Rolled Steel Strip Edges
Edges—Cold-rolled carbon steel strip shall be supplied with one of the following edges as specified:
No. I—A prepared edge of a specified contour (round or square) that is produced when a very accurate width is required or when an edge condition suitable for electroplating is required, or both.
No. 2—A natural mill edge carried through the cold rolling from the hot-rolled strip without additional processing of the edge.
No. 3一An approximately square edge produced by slitting on which the burr is not eliminated. This is produced when the edge condition is not a critical requirement for the finished part. Normal coiling or piling does not provide a definite positioning of the slitting burr.
No. 4—An approximately rounded edge. This edge is produced when the width tolerance and edge condition are not as exacting as for No. 1 edges.
No. 5—An approximately square edge produced from slit edge material on which the burr is eliminated.
No. 6—An approximately square edge. This edge is produced when the width tolerance and edge condition are not as exacting as for No. I edges.
Skived Custom-shaped edges produced by mechanical edge shaving with special tooling.

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 applications 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 applications. 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.
1074 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.
