Q195 Steel Equivalent, Properties, and Q195 vs Q235 Comparison

Q195 steel is one of the most commonly used low carbon steel grades in China, widely applied in the production of cold rolled steel coil and sheet. It is often compared with Q235 steel and referenced internationally through its equivalent grades such as ASTM A1008, JIS SPCC, and EN DC01.

• What is Q195 steel equivalent to in international standards?
• How does Q195 differ from Q235?
• What is Q195 galvanized sheet used for?

This guide explains the Q195 steel equivalent in global standards, clarifies the difference between Q195 and Q235, and explores Q195 galvanized sheet applications— helping buyers and engineers make informed sourcing decisions for wholesale Q195 cold rolled steel plate supply.

What Is Q195 Steel Equivalent To?

When sourcing materials internationally, knowing the Q195 steel equivalent material helps ensure compatibility with local standards and consistent performance in forming or stamping operations. Q195 belongs to the GB/T700 standard and shares properties with several foreign grades, though exact equivalence requires verifying mechanical data.

Standard	Equivalent Grade	Notes
ASTM (USA)	A1008 (Commercial Quality – CS Type A)	Closest in application and carbon content. However, A1008 is typically used for cold-formed steel, and detailed specs may differ.
JIS (Japan)	SPCC (Commercial Cold Rolled Steel)	SPCC and Q195 are commonly used interchangeably for low-strength, non-critical applications like stamping, household appliances, and automotive panels.
EN (Europe)	DC01 (EN 10130)	A cold-rolled low-carbon steel grade used for forming applications. Similar tensile strength and yield point to Q195.

Note: The ASTM equivalent of Q195 steel is generally A1008 commercial quality, but properties should always be confirmed before substitution.

Chemical Composition Comparison

Element	Q195	SPCC	DC01
C	≤ 0.06%	≤ 0.08%	≤ 0.12%
Mn	≤ 0.35%	≤ 0.45%	≤ 0.60%
P	≤ 0.035%	≤ 0.030%	≤ 0.045%
S	≤ 0.035%	≤ 0.030%	≤ 0.045%

Q195 steel has the lowest carbon and manganese content, giving it superior ductility and easier cold forming.

Mechanical Properties of Q195 Steel

Property	Q195	SPCC	DC01
Yield Strength (MPa)	≥195	≥205	140–280
Tensile Strength (MPa)	315–430	270–410	270–410
Elongation (%)	≥33 (t≤1.2mm)	≥28	28–36

These Q195 steel properties make it ideal for drawing, stamping, and welding applications requiring smooth surface finish and dimensional accuracy.

Q195 vs Q235 Steel: Composition and Strength Comparison

Although both belong to the GB/T700 standard, Q195 vs Q235 steel differ significantly in chemical composition and mechanical strength.

Chemical Composition

Element	Q195 (max)	Q235 (max)
C (Carbon)	0.06–0.12%	0.12–0.20%
Mn (Manganese)	0.25–0.50%	0.30–0.70%
Si (Silicon)	≤0.30%	≤0.30%
S, P (Impurities)	≤0.050%	≤0.045%

Summary: Q195 steel has lower carbon and manganese content, which gives it better ductility but slightly lower strength.

Mechanical Properties

Property	Q195	Q235
Yield Strength (MPa)	≥195	≥235
Tensile Strength (MPa)	315–430	375–500
Elongation (%)	≥33	≥26

Summary:

• Q195 grade steel is softer and more ductile, ideal for cold forming and welding applications.
• Q235 steel has higher strength, more suitable for load-bearing structural components.

Applications

Grade	Typical Uses
Q195	Furniture parts, low-pressure pipelines, wire drawing, cold stamping
Q235	Bridges, structural steel parts, heavy machinery components

Conclusion: Choose Q195 if you prioritize cold formability and cost; choose Q235 for stronger mechanical performance.

What is Q195 Galvanized Metal Sheet?

Q195 galvanized steel sheet (or Q195 galvanized coil) is made by coating cold rolled Q195 steel with zinc via hot-dip or electro-galvanizing. The zinc coating enhances corrosion resistance and appearance.

Main Features:

• Base Material: Q195 cold rolled steel
• Zinc Coating: Zinc (Z20–Z275 or more)
• Standard Coating Weight: 30–275g/m²
• Form: Sheet or coil
• Surface Types: Regular spangle, zero spangle, minimized spangle

Applications of Galvanized Q195 Steel

Industry	Use Case
Construction	Roofing sheets, wall cladding, ducting
HVAC	Air ducts, ventilation pipes
Furniture	Steel cabinets, enclosures, bed frames
Automotive	Inner panel structures, support frames
Agriculture	Grain silos, steel fencing, sheds

Galvanized Q195 steel sheet combines the formability of low carbon steel with the durability of a zinc finish, making it ideal for both indoor and outdoor usage.

Q195 Steel Coil or Sheet: Which to Choose?

Both Q195 cold rolled coil and Q195 sheet refer to the same material in different packaging formats. Here’s a quick comparison:

Format	Description	Use Case
Q195 steel coil	Continuous roll, convenient for mass processing	Slitting, stamping, roll forming
Q195 steel sheet	Flat cut-to-length plates	Custom fabrication or retail supply

If you require large quantities, Q195 cold rolled steel coil is more efficient. For smaller or customized batches, opt for Q195 steel sheet.

FAQ: Q195 Steel Common Questions

• Q: Is Q195 same as SPCC or DC01?
  A: They are similar low-carbon steels for forming use, but Q195 has slightly lower carbon content and better ductility.
• Q: Can Q195 replace Q235?
  A: Not directly. Q195 vs Q235 steel shows different mechanical properties — Q195 suits stamping, while Q235 is structural-grade.
• Q: What’s the typical coating for galvanized Q195 sheet?
  A: Standard coating weights range from Z40 to Z275 depending on environmental exposure.
