The high nickel, molybdenum, and copper content of X1NiMoCu25-20-5 stainless steel tube provides excellent corrosion resistance, particularly in chloride-containing environments. The chromium content enhances the material's resistance to oxidation and scaling at high temperatures, while the low carbon content minimizes the risk of intergranular corrosion.

Mechanical Properties

The mechanical properties of X1NiMoCu25-20-5 stainless steel tube, as specified in the EN-10217-7 standard, are as follows:

Steel name: X1NiMoCu25-20-5

Steel number: 1.4539

Tensile strength: minimum 620 Mpa

Yield strength: minimum 310 Mpa

Elongation: minimum 30%

Hardness: maximum 290 HBW (Brinell hardness)

These mechanical properties make X1NiMoCu25-20-5 stainless steel tube highly suitable for applications that require high strength, toughness, and resistance to corrosion. The high tensile and yield strength ensure that the tube can withstand high-pressure applications, while the high elongation allows the material to undergo significant deformation without fracturing.
Furthermore, the maximum Brinell hardness of 290 HBW indicates that the material is relatively easy to machine, and the low carbon content helps to minimize the risk of work hardening during fabrication.
Overall, X1NiMoCu25-20-5 stainless steel tube is a high-performance material that offers excellent mechanical properties, making it an ideal choice for demanding industrial applications.

Inspection and testing

The inspection and testing of X1NiMoCu25-20-5 stainless steel tube, as per the EN-10217-7 standard, are crucial to ensure that the material meets the required quality standards and specifications. The following inspection and testing methods are typically employed:
1. Visual Inspection: The tube is visually inspected to ensure that it is free from any surface defects such as cracks, pits, or corrosion.
2. Dimensional Inspection: The tube's dimensions, including outer diameter, wall thickness, and length, are measured to ensure they are within the specified tolerance limits.
3. Non-destructive Testing (NDT): Non-destructive testing methods such as ultrasonic testing, eddy current testing, or magnetic particle inspection are used to detect any internal defects or discontinuities.
4. Chemical Analysis: Chemical analysis of the material is conducted to verify that its composition meets the required specifications.
5. Mechanical Testing: Tensile, yield, and elongation tests are performed to evaluate the material's mechanical properties.
6. Corrosion Testing: Corrosion testing is conducted to determine the material's resistance to various corrosive environments.
7. Pressure Testing: Pressure testing is carried out to ensure that the tube can withstand the specified pressure without leaking or failing.
Overall, the inspection and testing of X1NiMoCu25-20-5 stainless steel tube are critical to ensure that the material meets the required quality standards and specifications and performs as intended in demanding industrial applications.

Pressure and Temperature Ratings

The pressure and temperature ratings of X1NiMoCu25-20-5 stainless steel tube, as per the EN-10217-7 standard, depend on several factors such as the tube's diameter, wall thickness, and operating conditions. The maximum allowable working pressure and temperature for X1NiMoCu25-20-5 stainless steel tube, assuming seamless construction, are as follows:
At 20°C, the maximum allowable working pressure is 40 bar for tubes with an outside diameter of up to 168.3 mm and a wall thickness of up to 6.3 mm. For larger diameters or thicker walls, the pressure rating decreases.
At 100°C, the maximum allowable working pressure is 35 bar for tubes with an outside diameter of up to 168.3 mm and a wall thickness of up to 6.3 mm. For larger diameters or thicker walls, the pressure rating decreases.
At 200°C, the maximum allowable working pressure is 30 bar for tubes with an outside diameter of up to 168.3 mm and a wall thickness of up to 6.3 mm. For larger diameters or thicker walls, the pressure rating decreases.
At 300°C, the maximum allowable working pressure is 25 bar for tubes with an outside diameter of up to 168.3 mm and a wall thickness of up to 6.3 mm. For larger diameters or thicker walls, the pressure rating decreases.
It is essential to note that these values are based on the assumption that the tube is operated within the specified temperature and pressure range, and all other factors are within acceptable limits. Any deviation from these conditions may affect the tube's pressure and temperature ratings, and it is therefore important to consult with the manufacturer or the relevant standard for accurate information.

Standard marking for steel tubes

According to the EN-10217-7 standard, X1NiMoCu25-20-5 stainless steel tube should be marked with the following information:
1. Manufacturer's name or trademark
2. Tube size (outside diameter and wall thickness)
3. Steel grade (X1NiMoCu25-20-5)
4. Heat number (unique identification number of the tube's production batch)
5. Standard number (EN-10217-7)
6. Marking of the approval organization (if applicable)
7. Any additional markings required by the purchaser or the relevant regulatory authorities
The marking should be clear and permanent, and it should be applied to each tube, preferably near the ends, using a suitable method such as stamping, etching, or painting. This information is crucial for identifying the tube's material properties, origin, and compliance with the relevant standards and regulations. It also helps to ensure traceability and quality control throughout the production, distribution, and installation processes.

Standard packing for steel Tubes

As per the EN-10217-7 standard, X1NiMoCu25-20-5 stainless steel tube should be packed and shipped in a way that ensures its protection from damage, corrosion, and contamination during transportation and storage. The following are the recommended standard packing methods for stainless steel tubes:
1. Bundles: Tubes are bundled together and secured with steel straps or wires to prevent them from rolling or shifting during transport. The bundles should be compact and sturdy, with a maximum weight of 3,000 kg.
2. Wooden Boxes: Tubes are packed in wooden boxes with appropriate cushioning materials such as foam or cardboard to prevent damage from impact or vibration during transit.
3. Plastic Caps and End Protectors: Tubes are fitted with plastic caps or end protectors to prevent contamination from dust, moisture, or other foreign matter. The caps or protectors should be securely fastened to the tube ends.
4. Marking: Each bundle or box should be marked with the necessary identification and handling information, including the manufacturer's name, tube size, steel grade, heat number, and quantity.
The packing should comply with the relevant regulations and standards and be suitable for the intended mode of transportation (e.g., land, sea, or air). It is crucial to handle and store the tubes carefully and avoid any conditions that may cause damage, deformation, or corrosion.
