The Mandrel bar offered by Anssen Memallurgy Group Co., Ltd. is manufactured from alloy steel grades 34CrMo4 or 42CrMo4, commonly known as chromium‑molybdenum steel. The supplier lists the material as a high‑grade alloy suitable for the Mannesmann plug‑mill process used to produce large‑diameter seamless pipes. Bars are hot‑rolled to achieve precise dimensional tolerances and are supplied in a range of lengths and diameters. The product description highlights high tensile strength and durability as key performance attributes.
Alloy steel 34CrMo4 typically exhibits a tensile strength of 900‑1100 MPa and a hardness of 260‑300 HB, while 42CrMo4 offers slightly higher strength, meeting standard specifications for pipe‑making mandrels. Standard chemical composition for 34CrMo4 includes 0.33‑0.38 % C, 0.90‑1.20 % Cr, 0.15‑0.25 % Mo, with the balance being iron, which is typical for this grade. The hot‑rolled finish provides improved surface quality and mechanical properties, aligning with industry expectations for seamless pipe production.
Primary customers are oil‑and‑gas pipeline manufacturers, petrochemical plant builders and infrastructure firms that require reliable raw material for tube mills. The bars are traded in bulk quantities and can be shipped in containers or on open‑deck vessels, with packaging that protects the hot‑rolled surface. The listing does not disclose minimum order quantities, lead times or payment terms, so buyers should request these details directly. Prospective importers are encouraged to obtain the latest material test certificates and confirm compliance with relevant ISO or ASTM standards.

Anssen Memallurgy Group Co., Ltd. is based at Shengli Street, Dalian 116000, China. The company is classified under the “imported” supplier tier and carries a “harbor” trust tier, indicating a vetted status for cross‑border trade. Its response metrics show a 0 % response rate, meaning communication may require follow‑up.
The supplier’s profile does not disclose production capacity, certifications such as ISO 9001 or specific client references. It focuses on providing alloy steel mandrel bars for seamless pipe manufacturers. Importers should verify the factory’s quality management system and request recent mill test reports before committing to purchase.
The mandrel bar is a critical consumable component in the manufacturing of large-diameter seamless steel pipes using the Mannesmann plug mill process. Typically manufactured from high-grade alloy steels such as 34CrMo4 or 42CrMo4, these bars are hot-rolled to precise tolerances to ensure consistent wall thickness control during tube elongation. Widely sourced from global steel exporters, mandrel bars are traded in bulk by oil and gas, petrochemical, and infrastructure project buyers seeking reliable raw material inputs for their tube mills.

Before placing an order, verify the mill’s heat‑treatment condition and request a recent mill test certificate that confirms chemical composition, tensile strength and hardness. Ensure the supplier can provide documentation that the bars meet ASTM A335 and any additional client‑specific standards required for your pipe‑making process. Confirm the dimensions, tolerances and surface finish meet your engineering specifications.
Logistics for mandrel bars typically involve containerised sea freight or bulk handling on open‑deck vessels. Buyers should agree on Incoterms - FOB Dalian port or CIF destination port are common - and establish payment terms such as T/T against a confirmed LC. Because the supplier’s response rate is recorded as zero, set up a dedicated communication channel and obtain written confirmation of production lead times before shipment.
Quality assurance should include third‑party inspection of the alloy bars prior to loading, with checks on chemical composition, tensile strength, hardness and surface roughness. Request the mill test report, a compliance statement for ASTM A335 and any ISO 9001 certification the factory holds. Arrange for a pre‑shipment inspection by a recognised agency to document that the material meets the agreed specifications.
