Холоднокатаный лист из нержавеющей стали в рулоне

Cold rolled stainless steel sheet in coil is produced by further processing hot rolled stainless steel through precision rolling at room temperature. The material is supplied in coil form, allowing continuous processing, резка, and fabrication for industrial applications.

This product is widely used where жесткие допуски, гладкая поверхность, and consistent mechanical properties необходимы.

Cold Rolling Process of Stainless Steel

The cold rolling process involves multiple controlled steps to improve surface quality and dimensional accuracy.

1. Подготовка горячекатаного рулона

• Raw material starts as hot rolled stainless steel coil (black coil)
• Surface contains oxide scale and requires cleaning

2. Маринование

• Acid treatment removes oxide scale
• Produces a clean metallic surface for further rolling

3. Холодная прокатка (Room Temperature Reduction)

• Material is passed through rolling mills under high pressure
• Thickness is reduced with high precision
• Strength increases due to strain hardening

4. Отжиг (Термическая обработка)

• Restores ductility lost during cold rolling
• Conducted in controlled atmosphere furnaces

5. Скин Пасс / Темперирующая прокатка

• Light rolling process improves:
  • Плоскостность
  • Чистота поверхности
  • Механическая консистенция

6. Отделка поверхности

• Final finishes include:
  • 2Б (standard industrial finish)
  • бакалавр (яркий отожженный, зеркальный)
  • Brushed or polished surfaces

7. Slitting and Recoiling

• Coil is cut into required widths
• Recoiled for delivery or further processing

Key Characteristics of Cold Rolled Stainless Steel Coil

Cold rolling significantly enhances the performance of stainless steel.

1. High Surface Quality

• Гладкий, чистый, and uniform surface
• Suitable for decorative and hygienic applications

2. Жесткий размерный допуск

• Thickness accuracy typically within ±0,10 мм
• Идеально подходит для точного изготовления

3. Increased Strength

• Work hardening improves:
  • Предел текучести
  • Предел прочности

4. Excellent Flatness

• Minimal waviness
• Better performance in laser cutting and stamping

5. Хорошая формуемость (After Annealing)

• Maintains ductility for:
  • Гибка
  • Deep drawing
  • Формирование

Typical Thickness and Width Range

Примечания:

• Most common thickness: 0.5 мм – 3.0 мм
• Standard widths: 1000 мм, 1219 мм, 1500 мм

Механические свойства (General Range)

Values vary depending on grade (например, 304, 316, 430).
