Heat Treatment

Heat Treatment

Coil heat-treatment
  • Solution Annealing: Heat the 904L coil to 1090°C to 1175°C and then cool it rapidly (usually in water). This treatment restores the austenite structure, eliminates cold working stresses, and improves corrosion resistance.
  • Annealing: Heat 904L to 900°C to 1050°C and cools it slowly. This treatment is mainly used to reduce the internal stress of the material and increase flexibility and plasticity.
  • Quenching and Tempering: 904L is an austenitic stainless steel and cannot be hardened by quenching or tempering.
  • Aging Treatment: 904L stainless steel will not increase strength or hardness through aging treatment.

Characteristic

Characteristic

  • 904L stainless steel coil has excellent corrosion resistance, high strength and good weldability, and is particularly suitable for strong acid, chloride ion and marine environments.
  • Its low carbon content ensures low risk of intergranular corrosion after welding, and good forming and processing properties make it suitable for the manufacture of various complex shapes.
  • In addition, 904L coil provides a variety of surface treatment options to meet different application requirements, and is widely used in chemical, marine engineering, food and pharmaceutical, and architectural decoration.

Packing

Packing

To ensure that the 904L stainless steel coils are intact during transportation, the following packaging methods are used.

  • Moisture-proof protection: Wrap the coils with moisture-proof materials and kraft paper to prevent moisture and contamination.
  • End protection: Use plastic or metal end caps to protect the ends of the coils to avoid deformation and damage.
  • Outer layer fixation: Tie the coils with steel or nylon straps and add corner protection strips to prevent damage.
  • Pallet fixation: Place the coils on a sturdy wooden or metal pallet for easy loading and unloading and transportation.
  • Label identification: Clearly indicate the specifications, batch number, weight and handling instructions to ensure correct operation.
  • Waterproof and dustproof: Cover with plastic film to prevent moisture and dust from entering.
