What is another name for cold rolled steel?
Cold-rolled steel is known by several alternative names and designations across global standards, making it important for buyers, engineers, and procurement teams to understand its interchangeable terminology. In the steel industry, cold-rolled steel is often referred to as CR steel, cold-reduced steel, CRS, cold-rolled sheet (CRS), or cold-rolled coil (CRC). In different regions, it may also be identified by specific grade codes such as DC01, DC03, DC04, DC05, DC06, and DC07 in the EN 10130 standard, or SPCC under the JIS G 3141 standard.These alternative names help classify the material based on application, surface quality, and formability requirements.
1. Detailed Grade Comparison
Table 2. DC01–DC07 Grade Performance
| Grade | Formability | Yield Strength | Main Application |
|---|---|---|---|
| DC01 | ★★☆☆☆ | Medium | Cabinets, brackets, profiles |
| DC03 | ★★★☆☆ | Lower | Automotive parts requiring drawing |
| DC04 | ★★★★☆ | Low | Appliance housings |
| DC05 | ★★★★☆ | Very Low | Deep-draw components |
| DC06 | ★★★★★ | Ultra-Low | Fuel tanks, complex shapes |
| DC07 | ★★★★★ | Lowest | Precision multi-stage deep drawing |
The progression from DC01 to DC07 reflects increased ductility and reduced yield strength.
2. Classification of Cold Rolled Steel Grades
The EN 10130 standard widely used in global markets includes the following main grades:
Table 1. Cold Rolled Steel Grade Classification
| Category | Grades | Description |
|---|---|---|
| Commercial Quality | DC01 | General forming and bending |
| Drawing Quality | DC03 | Suitable for moderate drawing |
| Deep Drawing Quality | DC04, DC05 | Better ductility, low yield strength |
| Ultra-Deep Drawing | DC06, DC07 | Maximum elongation for complex shapes |
These categories help determine which grade is appropriate for applications ranging from simple bends to high-demand multi-stage forming.
3. Global Equivalent Material Grades
Cold rolled steel has equivalent classifications in other major standards such as JIS in Japan, ASTM in the United States, and ISO internationally.
Table 3. Global Equivalents of Cold Rolled Steel Grades
| EN Grade | JIS Equivalent | ASTM Equivalent | Notes |
|---|---|---|---|
| DC01 | SPCC | A1008 CS | Commercial steel |
| DC03 | SPCD | A1008 DS | Drawing steel |
| DC04 | SPCE | A1008 DDS | Deep drawing steel |
| DC05 | SPCE-SD | A1008 EDDS | Extra deep drawing |
| DC06 | SPCF | A1008 EDDS+ | Extra-extra deep drawing |
| DC07 | SPCE-SD (closest) | EDDS | Ultra deep drawing |
This table helps engineers substitute materials when certain grades are unavailable in local markets.
Our company can also supply the following cold-rolled steel grades:
DC01 – Designed for basic forming processes such as bending, embossing, beading and standard drawing operations.
DC03 – Intended for more demanding forming applications, including deep drawing and more complex profiling.
DC04 – Suitable for applications requiring high levels of formability.
DC05 – A deep-drawing grade developed to meet very high forming requirements.
DC06 – A special deep-drawing grade engineered for the highest demands in cold forming.
DC07 – An ultra deep-drawing grade tailored for extreme and highly challenging forming operations.
