1. Giới thiệu

• 304Củ, còn được gọi là 304J1 stainless steel, is an austenitic stainless steel that contains copper.
• Copper is added to the standard 304 alloy to partially replace nickel.

2. Các tính năng chính

• Việc bổ sung đồng (Củ) improves the elongation performance of cold-rolled sheets.
• It reduces the risk of cracking caused by excessive hardening and high residual stress during or after cold working.
• This alloy is ideal for applications requiring deep drawing hoặc bulging hiệu suất.

3. Ứng dụng

• Commonly used as a substitute for 304 in products with higher forming requirements, such as deep-drawn or expanded components.

4. Tiêu chuẩn

• The material is produced under the company-specific standard:
  • “304Cu Hot-Rolled Stainless Steel Strip Provisional Supply Technical Conditions.”

5. Thành phần hóa học

The composition details of 304Cu (Unit: %) are provided as per technical standards.

6. Performance Benefits

• Improved formability.
• Reduced risk of cracking during or after cold processing.

Điều này làm cho 304Cu stainless steel an excellent choice for demanding manufacturing processes.
