The ASTM B690 standard specifies the requirements for seamless steel pipes made of iron-nickel-chromium-molybdenum alloys. These pipes are specifically designed for high-temperature service. The material used in the production of these pipes exhibits exceptional strength, oxidation resistance, and durability, making it suitable for various industrial applications that require elevated temperatures.
The key features of ASTM B690 stainless steel tubes include:
High-temperature resistance: These tubes are designed to withstand extremely high temperatures, ensuring smooth and reliable operation under challenging conditions.
Corrosion and oxidation resistance: The iron-nickel-chromium-molybdenum alloys used in the manufacturing process offer excellent resistance against corrosion and oxidation, which enhances the lifespan and reliability of the tubes.
Seamless construction: The pipes are manufactured using seamless technology, ensuring a smooth internal surface and reliable performance with minimal risk of leaks or failures.
Superior mechanical properties: The material used in these stainless steel tubes possesses excellent mechanical properties, such as high tensile strength, good ductility, and exceptional toughness, making them suitable for demanding applications.
The chemical composition of the ASTM B690 stainless steel tubes is as follows:
| Element | Composition Range (%) |
|---|---|
| Nickel | 20.0 - 22.5 |
| Chromium | 22.0 - 24.0 |
| Molybdenum | 6.0 - 7.0 |
| Iron | Remainder |
| Carbon | 0.03 max |
| Manganese | 2.00 max |
| Silicon | 1.00 max |
| Phosphorus | 0.040 max |
| Sulfur | 0.030 max |
Note: The composition ranges are approximate and may vary slightly depending on the specific production methods and variations.
The mechanical properties of the ASTM B690 stainless steel tubes are as follows:
| Property | Minimum Value |
|---|---|
| Tensile Strength | 620 MPa (90 ksi) |
| Yield Strength | 310 MPa (45 ksi) |
| Elongation | 30% |
| Hardness (Rockwell) | HRB 90 |
Note: The values mentioned in the table represent minimum requirements, and the actual properties may vary depending on the specific manufacturing conditions.
The steel grade specified in ASTM B690 stainless steel tubes is UNS N08367, which is a high-alloy austenitic stainless steel. This steel grade is specifically designed for applications that require exceptional resistance to corrosion in acidic environments, high-temperature strength, and good mechanical properties.
ASTM B690 stainless steel tubes find applications in various industries where high-temperature and corrosive environments are encountered. Some of the common applications include:
Petrochemical industry: These tubes are extensively used in the petrochemical industry for processes involving high-temperature fluids and corrosive substances.
Chemical industry: The excellent corrosion resistance and high-temperature strength of these tubes make them suitable for handling chemicals and acids in various chemical processes.
Power generation plants: The tubes are widely used in power plants, particularly in boiler systems and steam generators, where they encounter high temperatures and pressure.
Oil and gas industry: ASTM B690 stainless steel tubes find applications in offshore and onshore oil and gas installations, where resistance to chloride-induced stress corrosion cracking is crucial.
While ASTM B690 stainless steel tubes offer exceptional performance, there are alternative grades available that can be considered based on specific application requirements. Some possible alternative grades include:
