ERW Black Steel Tube
Stancore Steel International supplies ERW black steel tubes made from carbon steel with a composition of 0.12 - 0.20% carbon and 0.30 - 0.70% manganese, meeting typical ASTM A53 Grade B requirements for structural and fluid transport applications. The tubes are electric resistance welded, ensuring consistent seam integrity and smooth internal and external surfaces suitable for threading and flanging.
These tubes are manufactured without surface coatings, retaining the natural black oxide finish common in industrial-grade carbon steel piping. The material’s low sulfur and phosphorus content (≤0.040% each) supports weldability and reduces brittleness under stress. In the global market, such tubes are typically produced in seamless or ERW forms, with ERW offering cost advantages for medium-pressure applications where seamless tubing is not required.
Commonly used in water distribution, gas lines, mechanical frames, and low-pressure fluid systems, buyers include construction contractors, pipeline installers, and machinery manufacturers across Southeast Asia and the Middle East. Packaging is typically in bundles secured with steel straps, shipped in 20-foot containers or breakbulk. Trade terms are typically FOB Mumbai or CIF, with MOQs negotiable based on order volume and delivery schedule.

Sourcing ERW Black Steel Tube from Stancore Steel International - India Import Guide
Before ordering ERW black steel tubes from Stancore Steel International, verify the material composition through a certified mill test report (MTR), confirm wall thickness tolerance, and request evidence of hydrostatic testing. Do not rely on the supplier’s claims alone - demand documented proof of compliance with ASTM A53 or equivalent standards. Ensure the tubes are free from visible seams, cracks, or scale that could compromise structural integrity.
Confirm the Incoterms (FOB Mumbai is typical), lead time (typically 20 - 30 days after deposit), and payment terms (T/T or L/C are common). Packaging should be specified to prevent rust during transit - ask if plastic wrapping or desiccants are included. Clarify whether the tubes are shipped in containers or breakbulk, as this affects handling costs at destination ports.
Perform a pre-shipment inspection for dimensional accuracy, weld quality, and surface condition. Check for uniformity in wall thickness using a micrometer and inspect the weld seam under light for irregularities. Request a certificate of conformity and packing list. Retain samples for testing after arrival, especially if used in pressure or structural applications where failure is not acceptable.
