ASTM A848–01 pdf free.Standard Specification for Low-Carbon Magnetic Iron.
ASTM A848 covers the requirements for wrought low-carbon iron having a carbon content of 0.015 % or less with the remainder of the analysis being substantially iron.
3. Ordering formation
3.1 Orders to this specification shall include as much of the following information as is required to describe the desired material:
3.1.1 ASTM specification number and alloy type.
3. 1. 2 Dimensions and Tolerances-The tolerances are to be mutually agreed upon between the user and the producer.
3.1.3 Quantity(weight or number of pieces).
3.1.4 Form and condit
3.1.5 Magnetic property requirements if they are otherwise than stated herein.
3.1.6 Certification of chemical analysis or magnetic prop- Ity evaluation. or both.
3. 1.7 Marking and packaging
3.1.8 End Use-Whenever possible, the user should specify Whether the product will be machined, blanked into flat pieces blanked and formed, or deep drawn to shape. This information will help the producer provide the most suitable product for the users fabrication practice.
3. 1.9 Exceptions to this specification or special requirements.
4. Chemical Composition
4.1 Alloys supplied to this specification shall conform to the requirements in Table 1. Three of the elements listed in Table 1. namely vanadium, titanium. and aluminum, are not required but may be added to suppress magnetic aging. If present. they must be analyzed and reported.
5. Form and Condition
5.1 These two alloys are capable of being produced in a wide variety of forms and conditions for fabrication into magnetic components. The desired form and condition shall be discussed with the producer to assure receiving the conect product. Available forms and conditions are:
5.1.1 Forging Biller—Hot worked and surface conditioned by grinding.
5.1.2 Hot-Rolled Product—Hot rolled: hot rolled and acid cleaned: hot rolled and annealed: hot rolled. annealed. and acid cleaned: hot rolled and mechanically cleaned: mechanical properties as specified.
5. 1 .3 Cold-Finished Bars—Cold drawn. centerless ground. mechanical properties as specified: or relay condition.
5.1.3.1 Relay condition applies to 1 in. (25.4 nun) round and less in diameter and certain shapes supplied in the cold-worked condition having up to 25 % reduction in area and capable of meeting Class 2 magnetic property requirements as defined in 6.5.
5.1.4 Strip—Cold rolled, cold rolled and annealed. deep draw quality. mechanical properties as specified: or relay condition.
5.1.4.1 Relay condition applies to cold-rolled strip 0.020 to 0.200 in. (0.51 to 5.1 iiuu) thick having up to 25 % reduction in thickness and capable of meeting Class 2 magnetic property requirements as defined in 6.5.
5.1.4.2 Ordering information for strip must include edge condition and mechanical property requirements.
5.1.5 Wire—Cold drawn. annealed, mechanical properties as specified or relay condition.
