| High Light | carbon steel oval tube ，guardrail construction steel tube ，precision steel tube with warranty | ||
These oval mild steel tubes, typically produced to the DIN 2391 / EN 10305-1 standard, are cold-drawn precision carbon steel tubes offered in grades ST35, ST37, ST45, and ST52. They’re designed for high accuracy in dimensions and surface finish, commonly used in hydraulic systems, mechanical engineering, and automotive components — making them ideal for guardrail applications due to their strength and precision.
Below is a table of chemical compositions for ST35, ST45, ST52, and ST37 (where available), based on recognized specifications:
| Steel Grade | C (max %) | Si (max %) | Mn (min %) | P (max %) | S (max %) |
|---|---|---|---|---|---|
| ST35 | 0.17 | 0.35 | ≥0.40 | 0.025 | 0.025 |
| ST45 | 0.21 | 0.35 | ≥0.40 | 0.025 | 0.025 |
| ST52 | 0.22 | 0.35 | ≤1.60 | 0.025 | 0.025 |
| ST37 | ≤0.17 | ≤0.35 | ≥0.35 | 0.04 | 0.04 |
Here are mechanical performance figures for ST35 and ST37 in various delivery conditions (cold drawn, etc.):
Cold drawn (BK1): Tensile Strength = 480 MPa, Elongation = 6%
Cold drawn + soft (BKW1): Tensile = 420 MPa, Elongation = 10%
Normalized (NBK1): Tensile = 340–470 MPa, Yield = 235 MPa, Elongation = 25%
Cold drawn (BK1): Tensile = 480 MPa, Elongation = 6%
Cold drawn + soft (BKW1): Tensile = 420 MPa, Elongation = 10%
Normalized (NBK1): Tensile = 350–480 MPa, Yield = 235 MPa, Elongation = 25%
Mechanicals for ST45 and ST52 weren't directly specified in the results; however, typical trends suggest ST52 offers higher yield and tensile strength (e.g., ST52 yield = ~520 MPa, tensile = ~600 MPa, elongation ~14%)
High dimensional accuracy & smooth finish – ideal for precision applications like guardrails.
Cold-drawn to ensure tight tolerances and improved surface quality.
Progressively stronger grades (ST35 → ST52) allow tailored strength based on structural needs.
Primary Standards:
DIN 2391: Cold-finished precision seamless tubes.
EN 10305‑1: Equivalent European standard for cold-drawn precision steel tubes.
No ASTM, GOST, JIS, GB equivalents were identified for these specific grades in the search results. If required, further research may find relevant cross-reference standards.
General Application Domains:
Hydraulic systems, pneumatic cylinders, mechanical and automotive engineering.
Guardrail Context:
These elliptical welded carbon steel tubes are ideal for guardrail structures due to their strength, precise dimensions, and attractive surface finish.
ST35/ST37: Suitable for standard guardrail structures in non-critical load-bearing sections.
ST45: Offers better tensile strength, beneficial for sections expecting moderate impact or stress.
ST52: Best for high-load or high-impact zones like end-posts, anchor points, or zones requiring extra structural resilience.
A: manufacturer,also can do trading.
A: Generally speaking,it is 10-15 days if the goods are in stock,or it is 30-40 days if the goods are not in stock,
it is according to quantity.
A: Yes, we could offer the sample for free charge but need pay the cost of freight.
A: Payment<=2000USD, 100% in advance. Payment>=2000USD, 30% T/T in advance ,balance before shippment.
