Description
ASTM B407 is the more commonly used standard for seamless nickel-iron-chromium alloy tubing. It specifies requirements for chemical composition, mechanical properties, and so on.
Products Description
ASTM B407 covers UNS N08120, UNS N08800, UNS N08801, UNS N08810, UNS N08811, UNS N08890, and UNS N06811 for cold-worked and hot-worked annealed seamless tubing.
Alloys UNS N08800 and UNS N06811 are typically used at operating temperatures up to 1100°F (593°C).
Alloys UNS N08120, UNS N08810, UNS N08811, and UNS N08890 are typically used at operating temperatures above 1100°F (593°C) where creep and fracture resistance is required and they are annealed to a controlled grain size for optimum performance. This temperature range.
