ASTM International Subcommittee A01.19 on Sheet and Strip Steel has made three significant changes to ASTM standards under its jurisdiction. The changes are: • Reporting of boron levels made mandatory; • Changes to size limitations of general requirements and product standards for hot rolled material; and • Addition of grades 90 and 100 for hot rolled sheet and strip products. Subcommittee A01.19…, Boron Reporting, Boron is often added to low carbon steels to achieve lower hardness and increased formability; however, the mechanical properties of cold reduced and annealed material produced from hot rolled coils containing boron are affected by its presence. The differences may or may not be desired, but the effects are important and cold rolled steel manufacturers need to be informed of the presence of…, Size Limitation Changes, The general requirements for hot rolled sheet and strip products are spelled out in Standards A 568/A 568M , Specification for Steel, Sheet, Carbon, Structural, and High-Strength, Low Alloy, Hot-Rolled and Cold-Rolled, General Requirements for, and A 635/A 635M , Steel, Sheet and Strip, Heavy-Thickness Coils, Hot-Rolled, Carbon, Structural, High-Strength Low-Alloy, and High-Strength Low-Alloy…, Ultra-High Strength Steel Grades, ASTM standards A 1011/A 1011M and A 1018/A 1018M were changed to include grades with 90 and 100 ksi [620 and 690 MPa] minimum yield strength. These grades have the designation ultra-high strength (UHSS) as a way to differentiate them from the high strength low alloy with improved formability (HSLAS-F) designation. The UHSS grades may achieve their high strength by some measure of transformation…

Ineffective removal of grease from restaurants poses a variety of serious environmental problems. Large quantities of grease in public sanitary sewer systems can cause stoppages of piping networks and create costly and time-consuming problems at treatment plants. Sewer backups resulting from grease can also create health hazards when raw sewage backs up into homes or businesses. While grease…

A proposed new specification currently being developed by ASTM Committee C27 on Precast Concrete Products addresses the issue of watertightness in septic tanks and grease interceptors. The proposed standard, WK7426, Specification for Resilient Connectors Between Reinforced Concrete Tanks and Pipes, is under the jurisdiction of Subcommittee C27.30 on Water and Wastewater Containers. "The entries…

Most standard hardness tests for steel, including the Brinell, Vickers and various Rockwell tests, are generally classified as bench testers. This means that the component being tested needs to be taken to the machine for hardness to be determined. In order to test larger pieces, such as forgings, a section would need to be removed from the forging in order for it to be tested. Since this is not…
