ASTM B168 Standard Specification
ASTM B168 / ASME SB 168 is a standard specification that covers the requirements for nickel-chromium-iron alloys (UNS N06600, N06601, N06603, N06690, N06693, and N06025) plate, sheet, and strip. ASTM B168 includes the chemical composition, mechanical properties, and other important characteristics that must be met by the manufacturer to ensure the quality of the product.
ASTM B168 UNS N06600 UNS N06601 Production Process
According to the ASTM B168 specification, nickel alloys 600 and 601 plates must meet certain criteria. First, ASTM B168 UNS N06601 must be made using a hot-working process, such as hot rolling, to ensure that they have the required mechanical properties. Second, the chemical composition of the alloy 600 601 plate must be within the specified range, to ensure that the plate has the desired corrosion and heat resistance.
ASTM B168 Specification Important Requirements
1. Plate thickness: The ASTM B168 nickel alloy 600 plate thickness must be within the specified range, which varies depending on the width of the plate.
2. Tolerance: The Inconel 600 sheet must have the required flatness and tolerances for both length and width.
3. Surface finish: The Inconel 601 plate must be free from surface defects or imperfections that could affect its performance.
4. Testing: The Inconel steel plate manufacturer and supplier must perform tests to ensure that the plate meets the required mechanical and chemical properties, such as tensile strength and elongation.
