Zirconium 702 price

Zirconium 702 is a commercially pure grade known for its exceptional corrosion resistance. Pricing is primarily driven by purity levels (minimum 99.2% Zr + Hf), form factor (plate, pipe, bar, or wire), and surface finish. Buyers should ensure the material meets ASTM B550 (for bars), ASTM B551 (for strips/plates), or ASTM B523 (for seamless tubes). Any requirement for low-hafnium content (nuclear grade) will significantly increase the price compared to industrial grade 702.

Because Zirconium 702 is frequently used in highly corrosive environments like acetic acid, hydrochloric acid, or urea production, the quality of the protective oxide layer is critical. For chemical processing equipment, buyers must verify weldability and ductility. If the application involves high-pressure heat exchangers, the ultrasonic testing (UT) results and hydrostatic test reports are non-negotiable quality benchmarks that may affect the final quotation.

To ensure industrial safety and material integrity, always request an EN 10204 3.1 Mill Test Certificate (MTC). This document should detail the chemical composition (specifically Iron + Chromium limits < 0.2%) and mechanical properties (Yield Strength ≥ 205 MPa). For international trade, ensure the supplier complies with ISO 9001 quality management systems and, if applicable, PED (Pressure Equipment Directive) for European markets.

While the initial price of Zirconium 702 is higher than stainless steel or titanium, its Life Cycle Cost (LCC) is often lower in aggressive media. It offers a service life exceeding 20 years in environments where other metals fail in months. When negotiating, focus on the Total Cost of Ownership (TCO), including reduced downtime and maintenance costs, rather than just the per-kilogram spot price.

The primary risk is material substitution or grade mixing, where lower-grade alloys are passed off as Zirconium 702. To mitigate this, use third-party inspection services (like SGS or BV) to conduct PMI (Positive Material Identification) testing before the balance payment is made. Additionally, be wary of prices significantly below the global market spot rate for Zirconium sponge, as this often indicates recycled scrap or non-compliant material.

Negotiate based on volume-based pricing tiers and raw material price indexing. Since Zirconium is a specialty metal, prices fluctuate with raw ore availability. Secure a fixed price for a specific validity period (e.g., 7-14 days) to avoid sudden spikes. For large projects, ask for staggered delivery schedules to manage cash flow while locking in bulk rates.

Zirconium is sensitive to surface contamination and physical damage. Ensure the contract specifies seaworthy wooden crate packaging with internal moisture-proof wrapping. For tubes and pipes, plastic end caps are mandatory to protect beveled edges. Use Made-in-China.com's secured payment and trade services to ensure funds are only released upon verification of shipping documents and compliance with the agreed-upon Incoterms (typically FOB or CIF).

Zirconium is often classified as a dual-use material due to its applications in the nuclear industry. Buyers must confirm the HS Code (typically 8109) and check if an Export License is required from the origin country. Ensure all documentation clearly states the end-use is for non-nuclear, industrial applications to avoid customs delays or seizures during cross-border transit.
