Pragati Metal is one of the largest manufacturers, exporter, stockiest, and supplier of Alloy 20 Flanges and many other products in the international market. These flanges have applications in numerous industries, which usually include tanks, piping, pumps, valves, and heat exchangers. Pragati Metal has gained lots of appreciation from the manufacturing world because of their excellence and dedication.
Alloy 20 Flanges is one of the popular flanges having high demand in the market. Pragati Metal has mastered the art of developing the finest designs as per standards keeping customer’s requirements in mind. The reason behind the high demand of Alloy 20 flanges is its material characteristics and chemical as well as physical properties. Alloy 20 is a nickel-iron-chromium austenitic alloy. It offers maximum resistance to acid attack, specifically sulfuric acid. It is highly resistant to corrosion, crevice corrosion, and pitting in chemicals, having sulfuric and chlorides, nitric, and phosphoric acids. The copper content in it protects it from sulphuric acid. High corrosion resistance makes it useful for other industries such as power generation and plastic industries. It also has niobium, which helps it in stabilization against sensitization and resultant intergranular corrosion. It has excellent fabricability. Alloy 20 can be formed by either hot working or cold working using traditional methods.
Pragati Metal uses the finest raw material for manufacturing along with highly automated and precise machinery, which are being operated by the highly skilled and trained workforce. Alloy 20 flanges, as well as other products, go through several quality check-ups at all levels of manufacturing, such as during heat treatment, welding, forging, etc. The quality of the product is something where we are not ready to make any compromise. We can assure you that the product manufactured by Pragati Metal gives excellent performance.
Our highly trained and skilled team has developed a new setup and structure, which reduces the overall cost of the alloy 20 flanges making it easily affordable at a reasonable rate. We assure proper packaging to avoid damage to the product for short as well as long runs. We are always ready to manufacture products in custom made specifications as per customer’s requirements.
