What Is The Cold Drawn / Soft（+LC (BKW)）?

Cold drawn / soft(+LC (BKW)) delivery state refers to the cold drawing process with slight deformation after final heat treatment, which allows for further processing such as cold bending and expansion within certain limits. It has the highest dimensional accuracy and high tensile strength, with a certain elongation coefficient, and is generally used for manufacturing automotive parts.

What are the characteristics of steel pipes in Cold drawn / soft(+LC (BKW)) delivery state?

1. Soft characteristics: Steel pipes in BKW delivery state undergo small deformation cold drawing after final heat treatment, allowing for cold deformation operations such as bending, expanding, etc. within certain limits.

2. Plasticity: Due to heat treatment and small deformation through cold drawing, steel pipes in BKW state have a certain degree of plasticity and can be reprocessed within a certain range.

3. Application scenario: This delivery state of steel pipes is suitable for situations that require certain plasticity and further processing, such as hydraulic fluids, engineering machinery, etc.
