: Material that is under 3/16 inch [5.00 mm] in thickness and 24 inches [600 mm] and over in width.
While material-specific standards like ASTM A240 define the exact chemical composition and mechanical properties of a grade, A480 provides the uniform rules for how those materials are measured, finished, and delivered. Core Content of ASTM A480 The standard covers several critical technical areas:
Surface condition determines both the corrosion resistance and aesthetic value of stainless steel. The ASTM A480 standard precisely classifies these finishes: Finish Type Common Designation Manufacturing / Appearance Profile No. 1 Finish
ASTM A480/A480M is the essential guide for the production and purchase of high-quality stainless steel flat-rolled products. It establishes the fundamental rules of manufacturing, chemistry, mechanical properties, and dimensional tolerances that ensure consistency and reliability across various product specifications. astm a480 a480m pdf
一個更關鍵的區別，在於的應用。標準中明確規定：
ASTM A480 classifies flat-rolled stainless steel into three precise categories based strictly on thickness and width: : Material measuring ] and over in thickness , and over ] in width. Sheet : Material measuring under ] in thickness , and ] and over in width. Strip : Cold-rolled material measuring under ] in thickness , and under ] in width. 3. Dimensional Tolerances
The dual designation ( and A480M ) ensures universal compliance by supporting both Inch-Pound (Imperial) units and SI (Metric) units independently. Scope and Purpose of ASTM A480/A480M : Material that is under 3/16 inch [5
The ASTM A480/A480M standard is widely used in various industries, including:
It defines the methodology for determining the chemical composition, ensuring that the finished product adheres to the chemical requirements of the specific material grade standard (e.g., ASTM A240 ). 3. Dimensional Tolerances
How many tension, hardness, or bend tests must be performed per lot. Why Engineers and Buyers Search for the ASTM A480 PDF The ASTM A480 standard precisely classifies these finishes:
This document is not about a specific grade of steel (like 304 or 316). Instead, it is the that dictates how those grades are tested, finished, marked, and certified. Without A480/A480M, a purchase order for "316L sheet" would be incomplete.
The specification is the foundational global standard governing the general requirements for flat-rolled stainless and heat-resisting steel plates, sheets, and strips . Published by ASTM International under the jurisdiction of Subcommittee A01.17, this standard establishes the mandatory rules for dimensional tolerances, surface finishes, chemical analysis, testing procedures, and packaging. When engineers, buyers, or metallurgists search for an ASTM A480 A480M PDF , they are typically looking to verify critical material compliance boundaries before purchasing or manufacturing stainless steel components.
. It is the "master" standard used by manufacturers and fabricators to ensure consistent quality and dimensions across various stainless steel products. Core Purpose and Scope Universal Guidelines
