Gr.STS410 steel pipes are high‑pressure carbon steel tubes offered by Suzhou Superior Steel Co., Ltd. in China. They are manufactured from STS410 carbon steel in compliance with JIS G3455, KS D3564‑SPPH42, DIN1630‑St44.4, ASTM A524 and ISO 2604/2 standards, making them suitable for demanding power‑plant and petrochemical applications. The product list includes a range of outer diameters and wall thicknesses, for example 17.3 mm×3.2 mm and 48.6 mm×6.4 mm, providing flexibility for different system designs.
Typical industry specifications for STS410 pipes include a carbon content up to 0.30 %, silicon 0.10‑0.35 %, manganese 0.30‑1.40 %, and phosphorus and sulfur each not exceeding 0.035 %. Mechanical properties are defined by a tensile strength greater than 450 MPa and an elongation exceeding 25 %, with a preferred range of 25‑30 %. The pipes undergo normalising or bright annealing heat treatment, and dimensional tolerances are generally ±0.05 mm, ensuring uniform mechanical performance. Standard packaging formats such as round, square, rectangle or hexagon are available to suit shipping requirements.
These pipes are widely used in boilers, high‑pressure fluid transmission systems and other energy‑sector installations where reliability under high temperature and pressure is critical. Suzhou Superior Steel can provide bulk quantities with custom end caps or plastic plugs, and offers standard trade terms including FOB or CIF from Chinese ports. Payment can be made via L/C or T/T, and buyers should confirm packaging and inspection requirements before finalising the order.

Before finalising a purchase, verify the exact grade (STS410), chemical composition limits and mechanical property data for the required pipe size. Request the latest mill test report and, if necessary, a sample for dimensional inspection to ensure tolerance compliance.
Discuss logistics early: the supplier can ship from Suzhou or nearby ports under FOB or CIF terms, with lead times dependent on order volume and any custom processing. Payment is usually arranged via L/C or T/T, and buyers should confirm the incoterm details and any freight forwarder requirements.
Implement a quality plan that includes third‑party inspection of dimensions, heat‑treatment records and pressure testing. Ask for certificates of conformity, mill test reports and any relevant ISO or CE documentation to guarantee that the pipes meet the specified standards.
