─

The chemical composition of X1NiMoCu20-18-7 stainless steel tube is carefully designed to provide exceptional strength, corrosion resistance, and thermal stability. The high percentage of nickel in the alloy provides excellent ductility and toughness, even at low temperatures. The addition of copper enhances the steel's resistance to corrosion in chloride environments, while the molybdenum improves its resistance to pitting and crevice corrosion.
It is important to note that the chemical composition of stainless steel tube X1NiMoCu20-18-7, as per the EN-10217-7 standard, must comply with strict requirements to ensure consistent quality and reliability. These requirements include precise percentages of each element and thorough testing and inspection of the finished product to ensure it meets the necessary standards.

Mechanical Properties

The mechanical properties of stainless steel tube X1NiMoCu20-18-7, as per the EN-10217-7 standard, are as follows:

Steel name: X1NiMoCu20-18-7

Steel number: 1.4547

Tensile strength: 600 – 800 Mpa

Yield strength: ≥ 260 Mpa

Elongation: ≥ 35%

Hardness: ≤ 215 HBW

These mechanical properties indicate that X1NiMoCu20-18-7 stainless steel tube is a strong and durable material that can withstand high pressure and extreme temperatures. The high tensile strength of 600-800 MPa indicates that the steel tube is capable of resisting deformation under pressure. The yield strength of ≥ 260 MPa means that the tube can withstand stress without undergoing permanent deformation. The elongation of ≥ 35% shows that the steel tube has good ductility and can bend and stretch without breaking.
The hardness of ≤ 215 HBW indicates that the steel tube is relatively soft and easy to form, making it suitable for a variety of manufacturing processes. The mechanical properties of X1NiMoCu20-18-7 stainless steel tube are achieved through a combination of careful alloy composition and precise manufacturing processes, including cold drawing and annealing.
It is important to note that the mechanical properties of stainless steel tube X1NiMoCu20-18-7 may vary depending on the specific manufacturing process, such as the tube's size, wall thickness, and heat treatment. Therefore, it is essential to follow the EN-10217-7 standard's guidelines to ensure consistent quality and reliability.

Inspection and testing

Stainless steel tube X1NiMoCu20-18-7 is subject to strict inspection and testing procedures to ensure its quality and reliability. These procedures are outlined in the EN-10217-7 standard and include the following:
1. Chemical Analysis: The chemical composition of the stainless steel tube is analyzed to ensure that it meets the required specifications. This analysis includes the measurement of the percentage of each element present in the steel.
2. Mechanical Testing: The mechanical properties of the steel tube, including tensile strength, yield strength, and elongation, are tested to ensure that they meet the required specifications.
3. Non-Destructive Testing (NDT): NDT is performed to detect any internal or surface defects in the steel tube that may affect its performance or integrity. Common NDT techniques include ultrasonic testing, magnetic particle testing, and liquid penetrant testing.
4. Dimensional Inspection: The dimensions of the steel tube, including its diameter, wall thickness, and length, are checked to ensure that they meet the required specifications.
5. Visual Inspection: A visual inspection of the steel tube is performed to check for any surface defects, such as scratches or dents.
6. Corrosion Testing: Corrosion testing is performed to determine the steel tube's resistance to corrosion in different environments, such as saltwater or acidic solutions.
All inspection and testing procedures are conducted in accordance with the EN-10217-7 standard to ensure that the X1NiMoCu20-18-7 stainless steel tube meets the necessary quality and reliability requirements. The results of these tests are recorded and documented, and the steel tube is only approved for use if it meets all of the required specifications.

Pressure and Temperature Ratings

The pressure and temperature ratings of stainless steel tube X1NiMoCu20-18-7, as per the EN-10217-7 standard, are determined based on the tube's size, wall thickness, and operating temperature. These ratings are important to ensure that the tube is suitable for its intended application and can withstand the pressure and temperature conditions it will be exposed to.
The maximum pressure rating for X1NiMoCu20-18-7 stainless steel tube varies depending on the tube's diameter and wall thickness, as well as the operating temperature. Generally, at room temperature, the maximum pressure rating for this steel tube ranges from 40 bar to 160 bar, depending on the tube size and thickness. At higher temperatures, the maximum pressure rating will decrease due to the reduction in material strength caused by thermal expansion and other factors.
The maximum temperature rating for X1NiMoCu20-18-7 stainless steel tube is typically around 350°C. This temperature rating is based on the tube's ability to resist thermal stress, which can cause deformation or failure at higher temperatures. The actual temperature rating of the steel tube will depend on factors such as the tube's wall thickness, the specific application, and any other external factors that may affect the tube's performance.
It is important to note that the pressure and temperature ratings of X1NiMoCu20-18-7 stainless steel tube may vary depending on the specific manufacturing process, including factors such as heat treatment and cold working. Therefore, it is essential to follow the EN-10217-7 standard's guidelines to ensure consistent quality and reliability and to consult with a qualified engineer to determine the appropriate pressure and temperature ratings for the specific application.

Standard marking for steel tubes

According to the EN-10217-7 standard, stainless steel tube X1NiMoCu20-18-7 should be marked with certain information to ensure traceability and compliance with the standard. The following information should be included on the tube:
1. Manufacturer's name or trademark
2. Tube dimensions (outside diameter and wall thickness)
3. Steel grade (X1NiMoCu20-18-7)
4. Heat number (unique identifier assigned by the manufacturer)
5. EN-10217-7 standard reference
6. Batch number (optional, assigned by the manufacturer)
7. Country of origin (optional)
The marking should be legible and durable, so it remains visible throughout the life of the tube. The marking can be made using various methods, such as stamping, stenciling, or laser engraving.
The standard marking helps ensure that the stainless steel tube X1NiMoCu20-18-7 meets the specified requirements and can be traced back to the manufacturer and production batch. This information can be useful in case of any quality or performance issues, as it allows for identification and investigation of the root cause. Therefore, it is important to ensure that the marking is properly applied and maintained throughout the tube's lifecycle.

Standard packing for steel Tubes

The standard packing for stainless steel tube X1NiMoCu20-18-7, as per the EN-10217-7 standard, typically involves wrapping the tube in protective material and securing it in a bundle for transport. The exact packing method may vary depending on the size and quantity of the tubes being shipped, as well as the mode of transport.
Typically, the tube will be wrapped in a protective material, such as plastic or paper, to prevent damage during transport. The ends of the tube may be capped or covered to prevent contamination or damage. The tubes may then be bundled together and secured with straps or other fasteners to prevent them from shifting during transport.
The bundles may be placed in wooden crates or boxes, depending on the size and quantity of the tubes. The wooden packaging should be treated to prevent any pest infestations during transport.
In addition to the protective packaging, the tubes should be clearly labeled with the necessary information, such as the steel grade, dimensions, and batch number. This helps ensure that the tubes can be easily identified and traced back to the manufacturer if necessary. It is important to follow the standard packing guidelines to ensure that the stainless steel tube X1NiMoCu20-18-7 arrives at its destination in good condition and meets the required specifications.
