NOTE 2— When turned bars are speci? Niagara LaSalle is exceptionally responsive to the needs of our customers and puts a high priority on providing uniformity in the machinability of our products in order to improve productivity for you.
This specification covers cold-drawn, stress-relieved carbon steel bars satm to mechanical property requirements.
Restricted Incidental Elements S2. You can rely on Niagara LaSalle for all of your steel bar needs. The result is a steel bar product s311 meets stringent standards and provides a wide variety of benefits, including:.
The values stated in each system are not exact equivalents, qstm, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
In this modern age, uniformity in the machinability of a product is a crucial factor in improved productivity, and we not only met this critical need, but exceeded aetm. Restricted Cast or Heat Analysis the surface of the material.

Class A are normal-draft cold-drawn and stress-relieved rounds, squares, hexagons, and flats. The steel shall be made by one or more of the following primary processes: Mechanical property testing is always the final operation after all processing is completed.
Standard “as drawn” finish is smooth, Accurate and dark in color.
Class B are heavy-draft cold-drawn and stress-relieved rounds and hexagons. The report shall include the name of the manufacturer, ASTM designation and year date and revision letter, if any, class and grade, heat number, size, and grain size if requested. Warpage tests are also regularly made as part of a standard quality assurance procedure.

Maximum seam depth of 0. Workmanship, Finish, and Appearance Link to Active This link will always route to the current Active version of the standard. The degree of restriction a3311 the number of elements so restricted are both subject to agreement between the manufacturer and the purchaser. Details of these requirements shall be agreed upon between the manufacturer and the purchaser. Materials and Manufacture 6.
Ground and Polished with special close tolerances available on order. If restraightened, then the same number of tests are again required. A lot shall consist of bars of the same size from the same heat which have been stress relieved in the same stationary furnace charge. Within the limits of good manufacturing and inspection practices, the bars shall astn free of injurious seams, laps, segregation, or other imperfections that, due to their nature, degree, or extent, will interfere with the use of the material in machining or fabrication of suitable parts.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Within the text, the SI units are shown in brackets. A uniform material which provides exceptional quality for Production, maintenance or special machine parts. Niagara LaSalle developed this groundbreaking process in and forever changed the economics of part production. Routine warpage tests are also conducted throughout the life of the die.
Historical Version s – view previous versions of standard. Wstm Inclusion Requirements Microscopical S4. For continuous type of treatment, a lot shall consist of 25 tons [25 Mg] or less of the same size of each heat, treated in the same cycle. One class, B, is cold drawn with higher than normal heavy drafts to provide higher strength levels, and aetm grades provide improved machinability. Combining values from the two systems may result in nonconformance with the speci? Parts you are now heat treating from Rc 23 to Rc The area of the sample to be examined should be agreed upon between the purchaser and the manufacturer, and the test specimen should be hardened by heating and quenched before being polished to avoid pits.
This was followed by the highest temperature stress relieving treatment possible to obtain a combination of properties, including strength, wear resistance, minimum warpage and excellent machinability. One class, B, is cold drawn with higher than normal heavy drafts to provide higher strength levels, and four grades provide improved machinability. Within the text, the SI units are shown in brackets. The importance of high temperature stress relieving to obtain maximum ductility, minimum warpage and excellent machinability is a a3111 part of the original patent.
The values stated in each system are not exact equivalents, therefore, each system must be used independently of the other.
