Popular Design for Borosilicate Glass Capillary Tubes - Alloy 800 (UNS N08800), Alloy 800H (UNS N08810), and Alloy 800HT (UNS N08811)  – Herui

Description

Alloy 800 (UNS N08800, NS111), Alloy 800H (UNS N08810, NS112), and Alloy 800HT (UNS N08811) are nickel-iron-chromium alloys designed to resist oxidation and carburization at elevated temperatures. The nickel content, 32%, makes the alloys highly resistant both to chloride stress-corrosion cracking and to embrittlement from precipitation of sigma phase. The general corrosion resistance is excellent. In the solution annealed condition, Alloys 800H and 800HT have superior creep and stress rupture properties.

General Properties

Alloy 800 (UNS N08800), Alloy 800H (UNS N08810), and Alloy 800HT (UNS N08811) are nickel-iron-chromium alloys designed to resist oxidation and carburization at elevated temperatures. The nickel content, 32%, makes the alloys highly resistant both to chloride stress-corrosion cracking and to embrittlement from precipitation of sigma phase. The general corrosion resistance is excellent. In the solution annealed condition, Alloys 800H and 800HT have superior creep and stress rupture properties. All three versions of the basic Alloy 800 have been approved as materials of construction under ASME Boiler and Pressure Valve Code, Section I-Power Boilers, Section III-Nuclear Vessels, and Section VIII-Unfired Pressure Vessels.

Alloy 800, Alloy 800H and Alloy 800HT are identical except for the higher level of carbon (0.05 to 0.10 percent) in Alloy 800H, and the addition of up to 1.00 percent aluminum + titanium in Alloy 800HT. Alloy 800 is normally used in this service at temperatures to approximately 1100F (593C). Alloy 800H and Alloy 800HT are normally used above approximately 1100F where resistance to creep and rupture is required.

The use and maintain of the sawblade

◎ The carbide tip of sawblade is very sharp, so process of using must be prevent the carbide tip.

◎ PeriodicaI cleaning and support the machine,the spindle’s running tolerance must be less than h7.

◎ The flanges must be parallel to each other,must be of the same diameter 1/3 of the sawblade’s diameter(formuIti—rip saw blade is 1/2.

◎ When instaIIion the sawbIade,it shaII be 5-6 teeth higher than board surface．

◎ Before operation,check the firmly of the sawblade,be sure nobody in front of the machine. Do not feed of operation check whether the machine is good for operaiton. Periodical check the function of the machine,the certicaI jump is less than ±0.02MM,and the flap is less than ±0.01.

◎ After continuous use,must be removed and cleaning the sawblade,get rid of the resin and sawdust of the sawblade of both sides.Other wise it would beinfluence the effect of using the sawblade.

◎ Deposit of the sawblade,must not be layer the sawblade,it is putted in the originaI package inside.

The renovate of the sawbIade

◎ The renovate of the carbide sawblade While it no longer sharpen and the horizontaI piece coarseaess. The power of using sawblade machine obviously Increase. When process materiaI,the materiaI appearred burst. The carbide tip exhaust more than 0.02MM.

◎ For the renovate the sawblade,it shouId be grinding by the a formal company, so be sure the quality of the sawblade after renovating.
