Introduction to ASTM A1086
ASTM A1086 specifies requirements to which electrical steel used in rotating electrical and electromagnetic devices shall conform. Permeability features and specified core loss are attained during mill processing. MaTestLab is one of the best testing service providers, with the best network of testing laboratories in the USA to carry out ASTM A1086 tests for our clients. Users can also opt for stress relief treatment during the lamination process to prevent the core features from diminishing. Silicon is the primary alloy in these steels; however, a small amount of aluminum is also present. The traditional production process for electrical steels is done in five steps: (i) hot-rolling; (ii) annealing; (iii) pickling; (iv) cold-rolling; and (v) decarburizing annealing. The permeability of the steel has to be kept as high as possible.
Test Methods for ASTM A1086
The method proceeds as follows:
| Apparatus Setup | The electrically thin-rolled steel is produced in an electrical furnace or a standard steel-making device. Silicon and aluminum are also added as alloys. |
| Major Steps | Hot-rolling; annealing; pickling; cold-rolling; decarburizing annealing |
ASTM A1086 Specimens
| Specimen Details | 0.10 mm to 0.30 mm steel is included in the specification. The specimens are run through the following steps: typical rolling; annealing and commercial rerolling |
| Specimen Preparation | The specimen is prepared in an electrical furnace after adding silicon and aluminum in specified amounts as alloys. |
| Specimen Dimensions | Nominal thicknesses: 0.10 mm to 0.30 mm. For flat-rolled non-oriented fully processed electrical steel in nominal thicknesses, ASTM A677 is followed, and for flat-rolled grain-oriented fully processed electrical steel, ASTM A876 is followed. |
ASTM A1086 Results
The findings of ASTM A1086 provide valuable information on the performance of electrical and electromagnetic devices at particular frequencies, depending on the core loss values. This data is significant for electrical engineers in selecting the most suitable electrical steels for applications in electrical appliances. By using the ASTM A1086 results, engineers and specialists can enhance the productivity and efficiency of electrical equipment in practical engineering applications.
Test Related to ASTM A1086ASTM A1086 is compatible with some ASTM protocols, including ASTM A677, which entails the conditions to which non-oriented flat-rolled electrical steels at commercial power frequencies shall conform.
