Cold Rolled Steel Coil
As a leading supplier of ASTM standard steel materials, GNEE STEEL focus on supplying a full range of DS Type A/B/C cold rolled steel coil (thickness 0.3-3.0mm, width 800-1500mm). By strictly following ASTM A1008/A1008M standards, we provide cost-effective material solutions for stamping fields such as automotive parts, home appliance manufacturing, and electromechanical housings.
- DS = Drawing Steel
Indicates that the steel is designed for the drawing, stamping, forming process and has better ductility and formability than the basic grade (CS - Commercial Steel).
- Type A, B, C = Sub-type
Distinguishes the range of mechanical properties and chemical composition requirements (especially carbon, manganese, phosphorus content) of different grades.
DS Type B Cold Rolled Steel Coil
The most commonly used stamping grade steel, equivalent to China's national standard SPCD, European standard DC03/DC04, and Japanese standard SPCD.
Balanced mechanical properties: tensile strength of about 270~380 MPa, high elongation (≥34%).
Suitable for most stamping parts (such as electrical housings, brackets, simple containers).

Typical Applications
DS Type B Cold Rolled Sheet: General stamping ace (main model)
Industry share: home appliance manufacturing (62%), general machinery (28%), building hardware (10%)
Classic cases:
Home appliance field: air conditioner housing (Midea/Gree supply chain), washing machine side panel, microwave oven cavity
Automotive secondary parts: seat bracket, battery tray, wiper base
Electromechanical equipment: motor protective cover, water pump housing, gearbox cover
Process adaptation:
▶ Continuous die stamping (≤800 times/minute)
▶ CNC bending (R angle ≥0.8t)
Relationship with other grades of American Standard
- Relationship with other grades of American Standard
Basic grade: CS Type A/B/C (Commercial Steel) → For general use (such as SPCC/DC01).
Deep drawing grade: DDS Type A/B/C (Deep Drawing Steel) → Better performance than DS type, used for complex deep drawing parts (such as SPCE/DC05).
Extra deep drawing grade: EDDS (Extra Deep Drawing Steel) → Highest formability (such as DC06/SPCF).
- Selection Recommendation
Prefer DS Type B: covers most stamping needs and is cost-effective.
Need deep drawing or complex forming → choose DS Type C or upgrade to DDS series.
Simple processing/cost-sensitive → DS Type A or CS series.
