AL6XN Fittings

Manufacturing Process Of AL6XN Fittings


Using a forging machine to lower the outside diameter and bevel the pipe end or extension is one method of making forged fittings.

Rolling Wheel

The core is inserted into the pipe using butt weld fittings. After that, processing the rim and pushing the exterior with a roller.


Expand the pipe end in the punching machine to the desired size and shape by using a tapered core.


for creating bend and elbow fits. There are three typical approaches. There are three or four rollers: one is for stretching, one for stamping, and the third is for rolling.


A rubber is inserted into the tube and compressed with a punch, causing the pipe to bulge; hydraulic bulging forming is an additional technique.

Chemical Composition of AL6XN Fittings

AL6XN is a high-alloy austenitic stainless steel known for its exceptional corrosion resistance. Its chemical composition typically includes nickel (24-26%), chromium (20-22%), molybdenum (6-7%), nitrogen (0.18-0.25%), and iron (balance). Additionally, it may contain small amounts of manganese, silicon, copper, phosphorus, sulfur, and carbon to fine-tune its properties. AL6XN fittings are widely used in demanding environments such as chemical processing, marine applications, and offshore oil platforms.

Mechanical Properties of AL6XN Fittings

AL6XN fittings are known for their exceptional mechanical properties, combining high strength and corrosion resistance. They exhibit a tensile strength of approximately 100 ksi (690 MPa) and a yield strength of around 45 ksi (310 MPa). With a remarkable elongation percentage of over 40%, these fittings offer excellent ductility, enabling them to withstand significant deformation before failure. Additionally, AL6XN fittings boast outstanding toughness and fatigue resistance, making them suitable for demanding industrial applications where reliability and durability are paramount.
