Navgraha Steel & Engg Company is a manufacturing company of AL6XN flanges. Stainless steel AL6XN Flnages are the most used metal, whether in daily needed products or for industrial tools. These flanges are offered with excellent quality and strength. We supply a large range of types and specifications of these flanges.
What is Stainless steel AL6XN?
AL-6XN is nickel of 24% and chromium of 22% composition and is a type of weldable stainless steel alloy. It consists of molybdenum of 6.3%, including other elements including nitrogen. The higher contents of nickel and molybdenum in the AL-6XN alloy benefits excellent chloride stress-erosion splinter resistance.
The features that they show are:
• Immunity for corrosive agents
• Great tensile capacity
• Highly durable
• Resistant to any degree of temperature
• Provides ease of forming and fabricating.
• Need very less maintenance cost
• Elegant outer look
• It lasts for many years
Such attributes of stainless steel make them be used for almost all tools and devices. The prices of such metals are also less expensive than others. Their weight is also less and incurs less cost for fabrication.
Why are Stainless Steel AL6XN flanges used extensively?
Stainless Steel AL6XN flanges have very few carbon traces in them. But the presence of carbon helps avoid sensitization during processes like welding. They are recognized as nitrogen-bearing superalloys. They are an austenitic range of steel. They can easily withstand chloride attacks. They combat seawater corrosion too. Such AL6XN flanges are 50% better performers with higher temperature limits.
Features:
• Works well with phosphorous acids.
• It fights with the nitrous solution as well.
• Have SCC feature that is stress corrosion cracking
• Applicable for low pH environments
• Being nickel contained alloy, they work better than other alloys
These AL6XN flanges can easily opt for marine- related applications. The content of molybdenum is approximately up to 6% in them, which makes them flexible for such uses. In addition, they are immune to work with acids. The basic material of AL6XN are available for a broad array of critical uses and applications.
Other uses of AL6XN flanges:-
• Pulp bleaching
• Piping equipment
• Steam surface condensers
• Nuclear power water piping
• Heat exchangers
