🎓SPHC vs. SPCC: A Must-Read Guide to Hot-Rolled and Cold-Rolled Steel.
2024/06/07
In the steel industry, Hot-Rolled Steel Plate (SPHC) and Cold-Rolled Steel Plate (SPCC) are two common steel plates conforming to JIS standards. However, many people are not familiar with their English origins and uses. Today, we will analyze the naming origins, key differences, and international communication methods for SPHC and SPCC, to help professionals in the industry more accurately select the right material.
📌 English Naming Analysis of SPHC and SPCC
🔸
Hot-Rolled Steel Plate SPHC
SPHC is a hot-rolled steel plate under the **JIS G 3131** standard. The name's origin is as follows:
✔
S
(Steel)
= Steel, indicating the material is steel
✔
P
(Pressed)
= Pressed, suitable for pressing processes
✔
H
(Hot-rolled)
= Hot-rolled, indicating it has undergone a high-temperature rolling process
✔
C
(Commercial)
= Commercial grade, suitable for general use
📌
Full English Name:
👉
SPHC = Commercial Hot Rolled Steel for Pressing
🔸
Cold-Rolled Steel Plate SPCC
SPCC is a cold-rolled steel plate under the **JIS G 3141** standard. The name's origin is as follows:
✔
S
(Steel)
= Steel, indicating the material is steel
✔
P
(Pressed)
= Pressed, suitable for pressing processes
✔
C
(Cold-rolled)
= Cold-rolled, indicating it has undergone a cold rolling process
✔
C
(Commercial)
= Commercial grade, suitable for general use
📌
Full English Name:
👉
SPCC = Commercial Cold Rolled Steel for Pressing
📌
International Communication for SPHC & SPCC
Although **SPHC & SPCC** belong to the JIS (Japanese Industrial Standards) naming system, these two materials may have **different English names** internationally. However, the **industry typically communicates using the SPHC / SPCC codes directly**.
🔸
Common English Names for Hot-Rolled Steel Plate SPHC
✔
Hot Rolled Steel Sheet (SPHC)
✔
JIS SPHC Hot Rolled Steel Plate
✔
SPHC Commercial Hot Rolled Steel
🔸
Common English Names for Cold-Rolled Steel Plate SPCC
✔
Cold Rolled Steel Sheet (SPCC)
✔
JIS SPCC Cold Rolled Steel Plate
✔
SPCC Commercial Cold Rolled Steel
📌
Industry Communication Practices
🔸In international trade, quotation, and procurement processes, buyers and sellers mostly use only the **SPHC or SPCC** codes and do not specifically mention the full English names.
🔸On **technical drawings and product specification sheets**, the full JIS standard name, such as **JIS G 3131 SPHC** or **JIS G 3141 SPCC**, may be indicated to ensure that suppliers and clients are referring to the same steel grade.
🔸When matching with **different national standards** (e.g., ASTM, EN, GB), it may be necessary to refer to the **corresponding international grades** (e.g., ASTM A1011, EN S235JR, GB Q195) to avoid misunderstandings.
📌
Hot-Rolled Steel Plate SPHC vs. Cold-Rolled Steel Plate SPCC: A Comparison of Differences
We have now understood the **naming origins and corresponding international standards** of Hot-Rolled Steel Plate SPHC and Cold-Rolled Steel Plate SPCC. But what are their differences in practical application? Next, let's look at the **differences in manufacturing method, surface condition, and processing characteristics**, to help you quickly identify the suitable material.
