Sanonpipe supplies EN10210 S355J2H hot-finished structural hollow sections, EN10219 S355J2H cold-formed welded structural hollow sections, and ASTM A106 Gr B Sch 40 seamless carbon steel pipes – all from 20,000+ tonnes permanent stock. With 7-15 days urgent delivery, full certifications, and CBAM-ready carbon footprint data, we are your reliable partner for construction, energy, and industrial projects worldwide.
EN10210 specifies hot-finished structural hollow sections of non-alloy and fine-grain steels. S355J2H offers 355 MPa minimum yield strength and -20°C impact toughness (27J), ideal for load-bearing steel frameworks in commercial buildings, stadiums, bridges, offshore platforms, and crane components.
Available in SHS (Square Hollow Section), RHS (Rectangular Hollow Section), and CHS (Circular Hollow Section). Hot-finished process delivers superior toughness, reduced residual stress, and excellent fatigue resistance.
Key grades: S235JRH, S275J0H, S275J2H, S355J0H, S355J2H, S355K2H, S355NH, S355NLH, S420NH, S420NLH, S460NH, S460NLH
EN10219 covers cold-formed welded structural hollow sections. S355J2H delivers the same 355 MPa yield strength and -20°C impact toughness through ERW manufacturing, offering tighter dimensional tolerances, smoother finish, and more economical pricing.
Available in SHS, RHS, and CHS – ideal for construction frameworks, mechanical engineering, wind turbine towers, and heavy machinery.
Key grades: S235JRH, S275J0H, S275J2H, S355J0H, S355J2H, S355K2H, S355NH, S355NLH, S420MH, S420MLH, S460MH, S460MLH
ASTM A106 Grade B (ASME SA106 Gr B) is the standard for seamless carbon steel pipe used in high-temperature and high-pressure applications. Sch 40 wall thickness (ASME B36.10) covers 1/2″ to 24″.
Key properties: Yield ≥240 MPa, Tensile ≥415 MPa, service up to 425°C. Widely used in power plants, refineries, boilers, main steam lines, and industrial fluid/gas transportation.
Available schedules: Sch 40, Sch 80, Sch 160.
EN10210 vs. EN10219 – What’s the Difference?
| Feature | EN10210 (Hot-Finished) | EN10219 (Cold-Formed) |
|---|---|---|
| Process | Formed at elevated temperatures | Formed at room temperature, ERW welded |
| Stress | Internal stresses relieved | Higher residual stress |
| Toughness | Superior, especially at low temperatures | Good |
| Tolerances | Standard | Tighter |
| Cost | Higher | More economical |
| Best for | Critical load-bearing, seismic, low-temperature, offshore | General structural, cost-sensitive projects |
