A213 T1, T5, T9, T11, T12, T22, T91 Alloy Steel Seamless Tubes

Alloy Steel Tubes, ASTM A213 Alloy Steel Seamless Tube, Alloy Steel T1 Seamless Tubes, Seamless Ferritic and Austenitic Alloy-Steel Boiler Tube, T5 Alloy Steel Tubing Distributor, ASME SA213 Grade T9 Alloy Steel Tube Supplier in Mumbai, India.


A213 T1, T5, T9, T11, T12, T22, T91 Alloy Steel Seamless Tubes are composed of steel elements with low carbon content to medium carbon content. To increase materials' strength, hardness, and corrosion resistance, alloying materials can be added in small quantities to improve their properties, such as hardness, strength, and corrosion resistance. Neminox Steel & Engineering Co. is a major supplier and producer of Alloy Steel Tubes in various shapes, forms, diameters, and various materials and grades of alloy steel tubes. Chromium, molybdenum, silicon, manganese, nickel, vanadium, phosphorus, and sulfur are some alloying materials that can be used. In our capacity as one of the most reputable Alloy Steel Tube Suppliers, we provide tubes in various grades and sizes. It can be found in a variety of standards, including ASTM A335, A213, and A691, among others. The grades range from T1 to T91, depending on the composition of the material. As one of India's top A213 T1, T5, T9, T11, T12, T22, and T91 Alloy Steel Seamless Tubes Manufacturers, we produce tubes with nominal bore sizes ranging from 1/8 inch to 26NB and outer diameters ranging from 12 inches to 5 inches, depending on the application. The wall thicknesses of the tubes vary from 0.3mm to 50mm, depending on their size. Seamless Alloy Steel Tube is available in schedules 20 through XXS and seamless or welded construction.

Low Alloy Steel Tube goods are available in various sizes, including single, double, and cut to length. The length of the products may be as long as 16000mm. However, the petroleum industry and high-temperature applications such as heat exchangers and oil and gas processing installations are where the majority of applications may be discovered. Please do not hesitate to contact us if you want more information on the various standards, such as the Alloy Steel Tube, or if you require a pricing list of products.
