With our high production capacity and system of quality, we are capable of producing high-quality and reliable tubes with a high level of corrosion resistance and mechanical strength that meet the changing needs of the current industrial application.
Understanding ASTM B704 Specifications
ASTM B704 is applied to welded tubes of nickel and nickel-based alloys to be used in high-temperature and hard-to-resist service. The specification provides chemical composition, mechanical, manufacturing, heat treatment and testing requirements and thus similar performance is ensured in specific applications.
The ASTM B704 Welded Tubes are obtained by means of automatic welding in the absence of filler metal, followed by the cold working and solution annealing. This is done to achieve homogenous grain, weld integrity and uniformity in the mechanical properties of the tube. These tubes are well accepted in pressure vessel, heat exchanger and chemical processing applications both at the domestic and international market.
Nickel Alloy Grades in ASTM B704 Welded Tubes
ASTM B704 tubes are produced using nickel and nickel-chromium alloys that are selected due to their thermal stability and low possibility of chemical corrosion. Common grades include:
- UNS N06600 (Inconel 600) - Good resistance to corrosion and oxidation.
- UNS N06601 (Inconel 601) - High temperature oxidation and carburization resistance.
- UNS N06690 (Inconel 690) - Good stress corrosion crack strength in hostile conditions.
The choice of the alloy is determined by operating temperature, exposure with chemicals, and system design, and is good to guarantee optimum performance and life.
Mechanical Properties and Chemical Composition
ASTM B704 welded tubes are also dependable with regards to control in chemical composition and mechanical characteristics. Nickel increases oxidation and corrosion resistance, whereas chromium and molybdenum prevent strength and thermal stability enhancement.

How Shubham Metals Manufactures ASTM B704 Welded Tubes
Advance equipment is utilized in the manufacturing of our tubes whereby the nickel alloy strips are shaped into tubes and welded without a filler metal. Cold working and solution annealing increase the mechanical properties and corrosion resistance.
Individually, tubes are straightened, dimensionally checked, and tested and are in compliance with ASTM B704 and international quality standards.
Sizes, Dimensions, and Supply Options
ASTM B704 welded tubes can be found in flexible sizes and specifications to meet the industrial requirements:
- Diameters and wall thicknesses as required by standards or custom.
- Random lengths supply or cut-to-length supply.
- Surface Finishes such as as-welded, pickled or bright annealed.
These are simple to integrate into both standard and engineered systems and therefore compatible with a variety of applications.
Industrial Applications of ASTM B704 Welded Tubes
The ASTM B704 welded tubes find application in environments that experience high temperatures and corrosion such as:
- Heat exchangers and condensers
- Superheaters, pressure vessels and boilers
- Chemical and petrochemical processing equipment
They are also resistant to thermal and chemical stress thus suitable in the continuous use of critical industrial systems.
