ASTM A105 Flange

ASME SA105N Blind Flange Manufacturer, A105 Class 300 Flange

ASTM A105 Flange is a specification of flanges. The specification can include different grades of stainless steel material made flanges. The flanges are of forged carbon steel and are meant for high temperature services. Navstar Steel is a leading manufacturer and supplier of the ASTM A105 Flange types.

Forged ASTM A105 Pipe Flanges, ASTM A105 N Screwed Flanges, Hot sale - check ASME SA105 Nippo Flanges Price in India.

The material has carbon, manganese, phosphorus, sulfur, silicon, copper, nickel, chromium, molybdenum and vanadium in its composition. Since the other materials are less than 1% of the composition, these are called the carbon steels. There are different types such as the SA105N Blind Flange which is used to close a pipe line. The flanges also have good strength properties. The minimum yield strength of the flanges is 250MPa and the minimum tensile strength is 485MPa. The material is also hard with a Brinell hardness score of 187.


There are different pressure classes such as class 150, 300 and up to 2500 and PN6 through PN64. The A105 Class 300 Flange and below don’t need heat treatment while the higher pressure classes can undergo heat treatment. The flanges over 4 inches nominal bore size are applied with annealing, normalizing, normalized and quenched or normalized and tempered types of heat treatments. The ASTM A105 Pipe Flanges can be forged as well. The material is good for welding applications. The boiler and pressure vessel guidelines as per ASME standards have to be followed while welding the material. There are also bolted as well as screwed flanges. When welding and bolting procedures are not appropriate, the ASTM A105 N Screwed Flange comes handy. The screwed flanges can be applied with threaded pipes to make a connection without the need for welding. Please contact us for the pricing and further information on the flanges.
