Alloy 20 / carpenter 20 tubes are having very good resistance ability to stress corrosion cracking. Seamless tubes are also resisting pitting corrosion and chloride ion corrosion. The content of copper in it is protecting against sulphuric acids. Welded tubes are press brake bent over the radius double the material thickness. Alloy 20 EFW tubes are possessing resistance ability excellently to the hot sulfuric acid and also it is resisting SCC. Alloy 20 / carpenter 20 pipes & tubes are packed carefully in bundles, wrapped using environmental poly bags, etc for safer delivering.

Alloy 20 is an austenitic SS that is highly recommended to manufacture the good quality of pipes and bars. The grade offers excellent corrosion resistance, pitting resistance and crevice resistance. These grades are useful in various industries due to its excellent resistive properties. Alloy 20 is better than any other alloy grade because they are columbium stabilized. There are many good chemical components present in the alloy due to which the grade offers good ease to workability and strength.

The pipes manufactured using this grade makes them durable in tough environmental situation. Natural Steels is one of the largest exporter, supplier and stockiest of high quality of ALLOY 20 Pipes. The pipes are packed efficiently in order to avoid any kind of severe damage and other disability. The industry is popular in the market due to their valuable services offered to the buyers across the world. high end finishing, accurate dimensions, good end finishing, and timely delivery of the pipes are some of the services that are highly appreciated by the customers.

Talking about the packaging of the ALLOY 20 Pipes, the industry wrap the pipes in poly bags and then pack and export in wooden cases, crates or pallets that are free from fumigation and other impurities. Besides, the sales representative of the industry briefs with the clients and completes all the documents formalities in order to ship the product out of India. The industry provides customization specification on the pipes varying in size, thickness and shapes as per the necessity of the buyers and manufacturing industries.

The general characteristics exhibited by the ALLOY 20 Pipes are abrasion resistance, good corrosion resistance, pitting resistance, resistance to acidic environment, good strength, improved toughness and hardness. The pipes are highly ductile and malleable as compared with any other grade alloy pipes of different specifications. Moreover, the enterprise offers several relevant documents along with the ALLOY 20 Pipes to their buyers. The documents helps in checking the quality if the pipes and also go through the description in order to find out where to use and how to use them. Fumigation certificate, welding procedure specification, QAP, heat treatment chart, material test certificates, raw material report and commercial invoice are some of the documents offered along with the pipes to the customers.
