Stainless Steel Seamless Pipe and Tube is made up of stainless steel materials. There are different stainless steel grades. The 304 grade is the most used and the 304 stainless steel pipes and tubes are cost effective. Navstar Steel is one of the leading Stainless Steel Pipe manufacturers in India.

The pipes range in dimensions according to the ASTM, ASME and API standards with specifications in ASTM A213, A249 and A269. There are welded as well as seamless pipes. The Stainless Steel Seamless Pipe is dimensionally more accurate than the welded pipes.

The Stainless Steel Tube is applied in general corrosive, commercial, industrial and marine applications as well. The different grades of the material make up the different physical and mechanical properties of the Stainless Steel Seamless Tube and the use cases. The ASTM A312 Pipe and the other specification define the service areas such as pressure vessel, high temperature applications etc. Please contact us for further information on the ASTM A312m Stainless Steel Tubing and their prices.

Seamless Pipe is a high-strength industrial pipe manufactured without any welding seam or joint. It is produced by piercing a solid billet and forming it into a hollow tube, which ensures uniform structure, superior strength, and high pressure resistance.

Seamless pipes are widely used in industries such as oil & gas, petrochemical, power plants, construction, boilers, and automotive sectors due to their excellent durability and ability to withstand high temperature and pressure conditions.

Key Features:

• No welding joint (uniform structure)

• High pressure and temperature resistance

• Excellent strength and durability

• Corrosion-resistant material options

• Smooth internal surface for better flow

Material Grades Available:

• Carbon Steel

• Alloy Steel

• Stainless Steel

• Mild Steel

The stiffness effect of molybdenum and niobium on the nickel-chromium matrix gives Inconel 625 plate its strength; hence, precipitation-hardening treatments are not necessary. This mixture of elements is often responsible for excellent resistance to a broad variety of unusually harsh corrosive conditions, as well as high-temperature symptoms such as oxidation and carburization. The properties of Inconel plate that render it appealing to the aerospace industry include high tensile, creep, and rupture strength; exceptional fatigue and thermal-fatigue strength; oxidation resistance; and excellent weldability and brazeability.

Inconel 625 sheets, also known as Nickel Alloy 625 sheets, are nickel-based and can withstand temperatures ranging from cryogenic extreme freezes to 1000 degrees Celsius/2000 degrees Fahrenheit. They are nickel-based and use columbium and molybdenum as refractory metals. ASTM B443 UNS N06625 Strip has a minimum yield strength of 430MPa and a minimum tensile strength of 940MPa due to the nickel chromium framework, molybdenum material, and strong solution strengthening.

These materials also have a strong magnetic permeability of 1.0006 and a melting temperature range of 1280 -1350 degrees Celsius. WERKSTOFF NR. 2.4856, UNS N06625, JIS NCF 625 Foil, BS NA 21, GOST 75, etc. are the grades of Inconel Alloy 625 sheets, plates, and coils. Inconel  625 plate specifications are sheet/plate ASME SB-443 / AMS 5599 / AMS 5869. Inconel DIN 2.4856 Slitting Coils are mainly used in the marine industry and offshore oil drilling companies. Inconel alloy 625 coils are frequently used in heat exchangers and condensers.
