ASTM B463 is a standard specification issued by ASTM International that covers nickel-chromium-molybdenum-columbium alloy (UNS N08020) plate, sheet, and strip. This specification specifically pertains to plates made from the nickel alloy known as Alloy 20.

Here are some key features and requirements of ASTM B463 nickel-chromium-molybdenum-columbium alloy plates:

1. Material: ASTM B463 covers plates, sheets, and strips made from Alloy 20. Alloy 20, also known as Carpenter 20 or UNS N08020, is a nickel-based alloy with excellent resistance to corrosion, particularly in sulfuric acid environments.

2. Manufacturing Process: Nickel-chromium-molybdenum-columbium alloy plates covered by ASTM B463 can be produced using various manufacturing methods, including hot or cold rolling, annealing, and other forming operations. The plates are typically supplied in the annealed condition.

3. Dimensions: ASTM B463 specifies the dimensions and tolerances for nickel-chromium-molybdenum-columbium alloy plates. This includes requirements for thickness, width, length, flatness, and other dimensional characteristics to ensure compliance with the specified standards.

4. Mechanical Properties: ASTM B463 provides guidelines for the mechanical properties of nickel-chromium-molybdenum-columbium alloy plates. These properties include tensile strength, yield strength, elongation, and hardness. The mechanical properties may vary depending on the specific heat treatment and thickness of the plate.

5. Testing and Certification: ASTM B463 requires certain tests to be performed on the nickel-chromium-molybdenum-columbium alloy plates to ensure their quality and conformance to the standard. These tests may include chemical analysis, mechanical testing, and non-destructive testing. The plates should be certified by the manufacturer to demonstrate compliance with the specified requirements.

If you have specific requirements for Alloy 20 plates or need further information, it is advisable to consult the ASTM B463 standard or reach out to reputable manufacturers or suppliers who specialize in nickel alloys and can provide material certifications and comply with the applicable specifications.

ASTM B435 is a specification standard issued by ASTM International that covers nickel-molybdenum-chromium-iron alloys (Hastelloy) in the form of rolled plates, sheets, and strips. Specifically, ASTM B435 specifies the requirements for Hastelloy alloy sheets made from various grades within the Hastelloy family.

Hastelloy alloys are known for their excellent corrosion resistance, high-temperature strength, and good fabricability. They are commonly used in aggressive chemical environments, such as chemical processing, petrochemical, and offshore industries. Here are some key features and requirements of ASTM B435 Hastelloy sheets:

1. Material Grades: ASTM B435 covers several Hastelloy grades, including Hastelloy B-2 (UNS N10665), Hastelloy B-3 (UNS N10675), Hastelloy C-4 (UNS N06455), Hastelloy C-22 (UNS N06022), Hastelloy C-276 (UNS N10276), Hastelloy C-2000 (UNS N06200), Hastelloy G-30 (UNS N06030), and Hastelloy N (UNS N10003). Each grade has its unique chemical composition and properties.

2. Dimensions and Sizes: ASTM B435 specifies the dimensions, tolerances, and sizes for Hastelloy sheets. The standard covers thicknesses ranging from 0.025 inches (0.63 mm) up to and including 0.187 inches (4.75 mm), with varying widths and lengths.

3. Mechanical Properties: ASTM B435 provides requirements for the mechanical properties of Hastelloy sheets, including tensile strength, yield strength, and elongation. These properties ensure the sheets can withstand the intended service conditions.

4. Chemical Composition: The standard outlines the chemical composition limits for the various grades of Hastelloy alloys. The composition includes the percentages of nickel, molybdenum, chromium, iron, and other elements present, which contribute to the alloys' corrosion resistance and other characteristics.

5. Testing and Certification: ASTM B435 specifies various tests to be conducted on the Hastelloy sheets, such as chemical analysis, tension test, and hardness test. The sheets must also be certified to demonstrate compliance with the specified requirements.

It is important to note that ASTM B435 primarily focuses on Hastelloy sheets and their general requirements. For specific applications or additional technical information, it is recommended to consult the detailed material datasheets or contact manufacturers or suppliers specializing in Hastelloy alloys.
