ASTM A980/A980M-2019 超高强度冷轧碳素钢薄板规格 Standard Specification for Steel, Sheet, Carbon, Ultra High Strength Cold Rolled
<div class="SectionLevel2"> <p class="subsec1 cdone2"><span class="Head3 cdone">1.1</span> This specification covers a cold rolled ultra high strength carbon steel sheet in coils or cut lengths. The product is available in five strength levels. The steel's strength is obtained by water quenching from an austenitic temperature resulting in a martensitic microstructure. This product is intended for miscellaneous applications where ultra high strength, weight saving, and good weldability are important.</p></div> <div class="SectionLevel2"> <p class="subsec1 cdone2"><span class="Head3 cdone">1.2</span> The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.</p></div> <div class="SectionLevel2"> <p class="WTOcaveat cdone2"><span class="Head3 cdone">1.3</span> <i>This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.</i></p></div>...

ASTM E272-2019 高强度铜基和镍铜合金铸件参考射线照片 Standard Reference Radiographs for High-Strength Copper-Base and Nickel-Copper Alloy Castings
<div class="SectionLevel2"> <p class="subsec1 cdone2"><span class="Head3 cdone">1.1</span> These reference radiographs illustrate various categories, types, and severity levels of discontinuities occurring in high-strength copper-base, nickel-copper, and related alloy castings. The reference radiograph films are an adjunct to this document and must be purchased separately from ASTM International, if needed (see <span class="Body-link1 cdone">2.3</span>). Categories and severity levels for each discontinuity type represented by these reference radiographs are described in <span class="Body-link1 cdone">1.2</span>.</p><div style="text-align:left;" class="NoteLevel1"> <p><span class="note cdone" style="text-transform: uppercase;">Note 1:</span> <span class="note cdone">The basis of application for these reference radiographs requires a prior purchaser supplier agreement of radiographic examination attributes and classification criterion described in Sections <span class="Note-link1 cdone">4</span>, <span class="Note-link1 cdone">7</span>, <span class="Note-link1 cdone">8</span>, <span class="Note-link1 cdone">9</span>, and <span class="Note-link1 cdone">10</span> of this standard.</span></p></div></div> <div class="SectionLevel2"> <p class="subsec1 cdone2"><span class="Head3 cdone">1.2</span> These reference radiographs consist of forty-five 5 by 7 in.
