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…

Sampling is a difficult but essential part of the coal production process. ASTM International Committee D05 on Coal and Coke hopes to streamline that process with the publication of new standard D 7256/D 7256M, Practice for Mechanical Collection and Within-System Preparation of a Gross Sample of Coal from Moving Streams. Practice D 7256/D 7256M is under the jurisdiction of Subcommittee D05.23 on…
