SPCC, SPCD, and SPCE are all designations for different grades of low-carbon, cold-rolled steel that are commonly used in the stamping and manufacturing industries. The key differences among these grades are as follows:

SPCC (Special Drawing Quality Cold-Rolled Steel):

This is the most basic of the three grades, with moderate formability and ductility.
SPCC is a cost-effective option for simple stamping and forming applications.

SPCD (Drawing Quality Cold-Rolled Steel):

SPCD offers improved formability and ductility compared to SPCC.
This grade is better suited for moderately complex stamping and deep drawing applications.
SPCD is often used for automotive body panels, household appliances, and other products requiring deeper draws.

SPCE (Extra Deep Drawing Quality Cold-Rolled Steel):

SPCE is the highest-formability grade among the three, with exceptional ductility and deep drawing capabilities.
This steel is optimized for the most challenging stamping and deep drawing operations, such as those found in the automotive industry for complex body panels.
SPCE typically exhibits the best combination of strength, ductility, and surface quality for deep draw applications.

Suitability for Deep Draw Stamping Prototypes:

Of the three grades, SPCE would be the most suitable for making deep draw stamping prototypes, as it offers the best formability and ability to produce complex, three-dimensional shapes.
SPCD can also be a viable option for deeper draw prototype parts, though it may have some limitations compared to SPCE.
SPCC would generally be better suited for simpler, less complex prototype stamping applications.

The choice of SPCC, SPCD, or SPCE for a deep draw stamping prototype would depend on the specific geometrical complexity and performance requirements of the part. Consulting with an experienced prototype supplier can help determine the most appropriate steel grade for a given project.
