Nickel & Nickel‑Alloy Bar Round Square Hex Flat Forged Bar In Stock‑Shaanxi Qianyi Tuoda

Опубликовано Engineering Team, Shaanxi Qianyi Tuoda Technology Co., Ltd от 2026-11-02

Shaanxi Qianyi Tuoda Technology Co., Ltd specializes in supplying finished nickel‑base long bar products for global heavy‑industry end‑users, equipment fabricators, machine shops and export trading houses. Our nickel alloy bar portfolio covers hot‑finished bar, cold‑drawn bar, peeled / centerless‑ground bright bar, square bar, hexagon bar, flat bar and heavy‑section forged bar. These materials are widely deployed across chemical processing plants, salt‑lake lithium extraction circuits, offshore oil‑gas subsea components, marine seawater handling systems, flue‑gas desulfurization units, petrochemical reactors, high‑temperature furnace hardware, valve & pump shaft manufacturing, aerospace auxiliary components and electro‑chemical equipment construction. We handle small‑quantity sample cut‑pieces, medium‑batch project orders and large‑volume bulk export contracts. Beyond standard stocked dimensions listed in the table below, we execute fully custom bar production according to customer drawings, including special tolerances, non‑standard lengths and demanding surface requirements.

Different nickel‑base bar grades follow dedicated ASTM specification standards: pure Nickel 200 / Nickel 201 complies with ASTM B160; Monel 400 nickel‑copper alloy follows ASTM B164; Hastelloy C276 falls under ASTM B574; Inconel 625 is governed by ASTM B446; Incoloy 800 series uses ASTM B408 for bar products. Every production batch can deliver EN 10204 3.1 mill test certificate, covering chemical composition, mechanical‑property test results, heat‑traceability records for third‑party inspection, project documentation and overseas customs clearance. Each alloy possesses unique physical density values which form the foundation of theoretical weight estimation: Nickel 200 / Nickel 201 = 8.89 g/cm³; Monel 400 = 8.80 g/cm³; Hastelloy C276 = 8.89 g/cm³; Inconel 625 = 8.44 g/cm³; Incoloy 800 = 8.11 g/cm³. It should be emphasized that hot‑rolled bar retains rolling tolerance, peeled‑ground bar removes extra surface layer, both factors will create deviation between theoretical calculation and actual delivered weight.

Our warehouse holds 50‑60 tons ready‑stock covering multiple grades, cross‑sections and sizes of nickel‑alloy bar. Our overall monthly supply capacity can reach up to 100 tons to satisfy tight‑schedule project deliveries. Since nickel raw‑material cost is heavily driven by international LME nickel metal price fluctuation, we do not offer static fixed unit pricing. All buyers shall refer to our official weekly price list to acquire real‑time updated quotations. For custom bar inquiries, send us the drawing, material grade, dimensions, tolerances, service conditions, inspection requirements, and destination. Our engineering‑sales team will evaluate theoretical weight, unit price, production lead‑time and feasible surface treatment options for your project.

Mainstream Nickel‑Alloy Bar Specifications & Theoretical Weight (Standard Length: 6000 mm)

Important Note: All weight figures presented in this table are purely theoretical reference values. Actual shipment weight shall be subject to physical weighing and official MTC report. Calculation formulas used:

• Round Bar weight per meter (kg/m) = π × (D/2)² × density × 0.000001
• Square Bar weight per meter (kg/m) = Side² × density × 0.000001
• Hex Bar weight per meter (kg/m) = 0.866 × AF² × density × 0.000001
• Weight per 6‑meter piece = weight‑per‑meter × 6

Hot‑finished bar has dimensional tolerance defined by relevant ASTM standards; peeled / centerless‑ground bar removes outer oxide and surface stock, which will reduce real‑world weight. Expected weight deviation ranges from ±3% up to 7% for hot‑finished heavy‑diameter bar. For formal commercial contracts, please negotiate weight‑acceptance criteria in advance with our sales engineer.

Grade‑by‑Grade Selection, Bar Form & Surface Finish Procurement Guidance

Nickel 200 and Nickel 201 are commercially pure nickel grades. Nickel 200 delivers excellent alkali‑media corrosion‑resistance; Nickel 201 features ultra‑low carbon composition to prevent intergranular corrosion under high‑temperature caustic service, widely used for caustic soda production equipment, electroplating fixtures and alkaline reaction‑vessel components. Monel 400 nickel‑copper alloy exhibits outstanding performance in seawater and hydrofluoric‑acid environments, commonly manufactured into pump shafts, valve stems, marine fasteners and brine‑processing mechanical parts. Hastelloy C276 nickel‑chromium‑molybdenum‑tungsten alloy resists mixed oxidizing‑reducing corrosive fluids including wet chlorine, ferric chloride and complex mixed‑acid conditions, the primary material for severe‑corrosion chemical reactors and flue‑gas desulfurization hardware. Inconel 625 is niobium‑molybdenum strengthened nickel‑base alloy balancing high‑temperature strength and chloride pitting‑corrosion resistance for offshore and high‑temperature process mechanical components. Incoloy 800 nickel‑iron‑chromium alloy provides reliable high‑temperature carburizing‑resistant performance for furnace rollers, radiant tubes and heat‑exchanger elements under long‑term thermal exposure.

Beyond grade selection, buyers must define bar form, manufacturing process, heat‑treatment condition and surface finish in purchase specifications. Hot‑finished bar is cost‑effective for subsequent heavy machining, retains rolling oxide scale and relatively wide dimensional tolerance. Cold‑drawn bar achieves tighter dimensional tolerance and smoother surface for light‑machining scenarios. Peeled or centerless‑ground bright bar removes surface defects, oxide layers and decarburized zones, ideal for shaft‑type parts with strict surface and dimensional requirements. Square bar, hexagon bar simplify wrench‑fit mechanical‑component machining; flat bar serves for bracket, rib and fixture fabrication. Heavy‑section forged bar applies for large‑diameter high‑load parts where rolled bar cannot meet grain‑structure requirements. Standard delivery condition for most nickel‑alloy bar is solution‑annealed or stress‑relieved; precipitation‑hardened grades can undertake aging heat‑treatment upon special customer request.

Critical procurement check‑list for nickel‑alloy bar inquiries: alloy UNS number, bar cross‑section shape, diameter / across‑flat dimension, width‑thickness for flat bar, single‑piece length, tolerance class, heat‑treatment state, surface finish, PMI test requirement, non‑destructive‑testing scope (UT / PT), MTC document type and packaging requirement. Our workshop can implement cut‑to‑size sawing service according to drawing dimensions. All export‑oriented nickel‑alloy‑bar goods adopt seaworthy fumigated plywood crate packaging with moisture‑proof paper wrapping to avoid surface scratch, collision and damp damage in long‑ocean‑voyage logistics.

As one‑stop corrosion‑resistant‑metal supplier, Shaanxi Qianyi Tuoda Technology also supplies supporting titanium products, nickel‑alloy plate, nickel pipe, nickel‑alloy flange and zirconium series materials. Consolidating multi‑category material sourcing from single manufacturer reduces multi‑supplier communication overhead, cross‑batch inspection risk and complex delivery‑management workload. Please keep in mind that theoretical‑weight data in above‑mentioned table is calculated by ideal nominal dimension and material density. Hot‑rolling tolerance, forging stock allowance and material removed during peeling‑grinding operation will inevitably generate weight deviation. Theoretical weight can be used for budget estimation, container‑loading calculation and preliminary quotation only, and cannot replace physical weighing for commercial settlement. Before signing formal purchase contract, please negotiate weight‑acceptance‑evaluation standard with our professional sales engineer.
