We stock a large range of carbon steels which can be slit to the customers requirement. We also have a wide range of excess offcuts which may be of interest.
High Carbon Steel Strip can be produced to a large variety of tensile strengths/hardnesses to suit the subsequent component-manufacturing processes and end-uses involved. The softened/annealed condition provides maximum deformability for more complex component shapes or, alternatively, lower relative wear on component-forming tools. In this condition hardnesses of 160 - 200 VPN (equivalent to tensile strength up to about 690 N/mm²) would be typical.

Type 2: 0.10 max
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 ma terial may be pinch rolled after the final anneal to improve flatness, uniformly oil, modify surface, obtain proper mechani cal properties, and minimize stretcher strains if required by the purchaser.
1 Soft spheroidized annealed high-carbon steel is in tended 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 appli cations 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 appli cations. 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 mini mum hardness should be established between the consumer and the producer.
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.
1040 is a medium-carbon steel composed of 0.37 to 0.44 percent carbon, 0.6 to 0.9 percent manganese, a maximum of 0.04 percent phosphorus and a maximum of 0.05 sulphur. The remainder is iron.
AISI 1040 carbon steel has high carbon content and can be hardened by heat treatment followed by quenching and tempering to achieve 150 to 250 ksi tensile strength.
AISI 1040 equivalent to EN8/080M40. An unalloyed medium carbon steel. AISI 1040 is a medium strength steel with good tensile strength. Suitable for shafts, stressed pins, studs, keys etc. 1040 must be pre-heated to 300 to 500 degrees F before welding and reheated to between 1100 degrees F and 1200 degrees F after welding. Otherwise, the area near the weld may develop cracks or become brittle and cause the part to fail during use.
This grade of steel is used for forged parts where the strength and toughness of the material are appropriate. C1040 may be used for the manufacture of forged crankshafts and couplings, along with a range of parts where the properties of heat-treated C1040 are suited to the application.
