ASTM B514 / ASME SB514 / Welded Nickel Iron Chromium Alloy Pipe supplier & distributor in India

ASTM B-514 / ASME SB-514
SPECIFICATION FOR WELDED NICKEL IRON CHROMIUM ALLOY PIPE.
UNS N08810 = INCOLOY 800 , UNS N08810 = INCOLOY 800H

1.Scope

1.1 This specification civers nikel=iron-chromium allyos in the forn of welded, cold-worked, and annealed pipe for general corrosive service and heat-resisting applications. These products are furnished in two alloys, UNS N08800 and N08810. Alloys UNS N08800 is employed normally in service temperaures up to and including 1100F(539?) Alloy UNS N08810 is employed normally in servise temperatures above 1100F where resistance to crep and rupture is requied, and it is annealed to develop controlled grain size for optimum properties in this temperature range.

1.2 This specification covers outside diameter and nominal wall pipe shown in ANSI B36.19. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of the specification.

1.3 The values stated in inch-pound units are to be regarded as the standard.
