Corrosion-Resistant Pure Nickel Bars for Manufacturing Environments

Manufacturing environments corrode equipment in predictable ways: chemical media attack welds and fittings, plating and treatment tanks demand materials that hold their surface, and process downtime from a failed component costs more than the material that failed. Pure nickel bars are chosen in these settings for a simple reason — documented corrosion resistance in saltwater and chemical media, backed by N6 and Ni200 industrial corrosion duty grades. DLX supplies four grades (N4, N6, Ni200, Ni201), custom sizes per drawing, and EN 10204 3.1 MTC with heat traceability on every shipment. The annealed baseline of ≥462 MPa, ≥35% elongation and 90-120 HB keeps machined components predictable, and production runs on an ISO9001 and SGS verified nickel-only line.

Size & Specification Overview

• Corrosion resistance in saltwater and chemical media — N6/Ni200 industrial corrosion duty.
• Four grades on one order — N4/N6/Ni200/Ni201 — match cost to the environment.
• Annealed baseline ≥462 MPa, ≥35% elongation, 90-120 HB — predictable machined components.
• EN 10204 3.1 MTC with heat traceability on every delivery.
• Custom sizes per drawing, with in-stock diameters for fast dispatch.

Grade selection follows the environment, not a default. For chemical media and plating service, N6 and Ni200 are the workhorse grades with industrial corrosion duty. Where process temperature rises, Ni201 extends the service envelope, and N4 (NP1) serves the strictest purity requirements for sensitive processes.

Diameter, length, straightness and surface are confirmed against your drawing before production, and tolerances are locked at that review — so process components built from bar stock meet their fit requirements.

Machined components in processing equipment rely on a repeatable baseline: ≥462 MPa tensile strength, ≥35% elongation and 90-120 HB hardness, documented per heat — so fabrication stays predictable from order to order.

Annealed is the standard temper for forming and machining; cold-worked tempers provide higher strength for structural parts. Specify the target strength or hardness on the drawing and the temper is set accordingly.

Indicative FOB China reference prices for bars; final quotation per grade, size, quantity and temper.

The 10 kg minimum order for bars covers drawing setup and heat allocation, so tolerances can be locked per drawing; wire and strip products are available at 5 kg MOQ.

Quality control for bars follows the shape, not a generic checklist:

• Incoming: raw nickel verified per heat before processing.
• In-process: diameter, length and straightness checked with calibrated instruments; surface inspected along the full length.
• Final: tensile and hardness testing sampled per heat; chemical composition verified per heat.
• Documentation: EN 10204 3.1 MTC with heat number, test results and full traceability.

Ni200/Ni201 bars are manufactured and tested to ASTM B160; N4/N6 follow GB/T 4435-2010. Testing methods and acceptance criteria follow the drawing specification and applicable standards.

Straight bars are bundled and protected against transit damage; longer lengths travel in export wooden cases, seaworthy-packed for container shipment. In-stock diameters can be dispatched promptly, and production lead time is 7-15 days after drawing and grade confirmation. Every order ships with the complete export documentation set: packing list, commercial invoice and mill test certificate.

Changzhou DLX Alloy Co., Ltd. is itself a manufacturer — 12,000 m² of production floor, 1,200 tonnes a year, running since 2002 — and that changes how it serves industrial buyers. A nickel-only line keeps corrosion resistance consistent across every heat; EN 10204 3.1 MTC documents each batch; and drawing-based production matches the tolerances manufacturing engineering specifies. When one manufacturer supplies another, the conversation starts from process reality: machining behavior, delivery rhythm and documentation — not marketing claims.
