Get A QuoteStainless steel coils for pipes are widely used in various industries due to their excellent corrosion resistance and durability.
Chemical Composition:
Typically, it contains elements like chromium (Cr), nickel (Ni), molybdenum (Mo), and iron (Fe). For example, in 304 stainless steel, chromium is around 18 - 20%, nickel about 8 - 10.5%, and the balance is mainly iron. Different grades have varying proportions to achieve specific properties.
Mechanical Properties:
• Tensile strength: It determines the coil's ability to withstand pulling forces. For common grades, it ranges from 515 MPa to 760 MPa.
• Yield strength: Indicates the stress at which permanent deformation begins. Values vary by grade.
• Elongation: Reflects the ductility, usually expressed as a percentage elongation before fracture.
Standard Specifications by Countries:
| Country | Standard Specification |
| USA | ASTM A240 (covers chemical and mechanical requirements for stainless steel sheet, strip, plate, and coil for pressure vessels and general applications) |
| Germany | DIN EN 10088 (defines the characteristics of stainless steels) |
| Japan | JIS G4305 (specifies the quality and dimensions of stainless steel plates, sheets, and strips) |
Popular Grades:
• 304: It is one of the most widely used grades. It has good corrosion resistance in general environments, suitable for applications like food processing equipment, kitchenware, and architectural trim.
• 316: With added molybdenum compared to 304, it offers enhanced corrosion resistance, especially in chloride-containing environments. Commonly used in marine applications, chemical processing plants.
Popular Q&A:
Q1: Why is 304 stainless steel so popular?
A: It has a balanced combination of good corrosion resistance, formability, and affordability. It can handle most daily use and mild industrial environments, making it suitable for a wide range of products.
Q2: How can I tell if the stainless steel coil is of good quality?
A: Check the surface finish for smoothness and absence of defects. Also, verify the material certificate provided by the supplier, which should show compliance with relevant standards in terms of chemical composition and mechanical properties.
Q3: Can stainless steel coils for pipes be welded?
A: Yes, most stainless steel grades can be welded. However, proper welding procedures and filler materials need to be selected according to the grade to ensure good weld quality and maintain the corrosion resistance of the joint.
