Every enquiry starts with the medium, the duty and the way the part fails in service. We review those three things first, because they decide the material, the coating and the geometry long before a product name does. The sectors below are the ones where we already know which questions control the outcome.
A sector tells us which variables usually dominate the decision. It does not tell us the grade, the coating, the geometry or the inspection scope. Those are set by the medium, the duty and the failure mode, and they are confirmed in the same technical review for every order.
The industry matrix below tells you which duty dominates. These three routes tell you how that duty is technically answered.
Mill forms, semi-finished products and machined components for corrosive, high-load and high-purity duty.
Coated and uncoated anodes for electrolysis, plating and cathodic protection duty.
PEM stacks, packaged generators and on-site electrolysis packages for hydrogen and chlorine duty.
Each sector is reviewed against the failure it actually sees in service, and matched to the route that addresses it.
Corrosive process service, heat exchange and containment equipment.
Chloride-bearing or reducing process media attack carbon steel and stainless within one process cycle, and weld heat tint opens the corrosion path.
Grade 2 titanium plate, seamless tube and fittings selected against the actual medium, with clad copper bimetal where the duty needs a copper-backed approach.
Seawater systems, ballast, hulls and offshore structures.
Continuous seawater exposure couples titanium to dissimilar metals, and splash-zone duty adds hydrostatic load and vibration on top of the corrosion duty.
Marine grade plate and seamless tube with fastener and sacrificial anode packages reviewed against galvanic isolation and the cathodic protection basis.
Structural, engine and high-performance components.
Supply is governed by the specification revision and the drawing, not by a generic grade name, and the approved process has to survive every lot.
Ti-6Al-4V plate, bar, billet and closed-die forgings with full heat traceability and first-article inspection to the customer-approved process.
Implant, instrument and bioprocess components.
An implant or bioprocess requirement is not closed by a material certificate — surface condition, cleaning and packaging carry equal weight.
Grade 23 ELI plate, bar, wire and precision balls supplied with surface condition, cleaning and packaging evidence agreed to order.
Pipelines, tanks, concrete and buried assets.
The protection criterion and the anode-bed geometry decide the design, and an anode dimension on its own does not meet either.
MMO linear, ribbon, tubular and disc anodes designed from the design current, with substrate grade and coating loading verified to order.
Disinfection, desalination and electrochemical water treatment.
Water treatment is a chemical duty and a mechanical duty at once — the anode has to survive the chemistry and the cell has to survive the flow.
Salt chlorination and hypochlorite cells with MMO anodes, sized from chemistry, flow and current density rather than from tank volume.
Decorative, functional and advanced plating lines.
A plating anode has to hold a stable current density without shedding into the bath, and the anode is only one part of the cell.
Platinised and MMO titanium anodes with baskets, racks and jigs, where substrate grade, geometry and coating type are selected together.
Hydrometallurgy and metal recovery operations.
Electrowinning deposits metal from solution, so electrolyte purity and current distribution decide the outcome more than the metal does.
MMO anodes, titanium cathode baskets and clad copper anodes, selected against the impurity species that concentrate in the anolyte.
Green hydrogen production, fuel cells and energy storage.
A hydrogen project is decided by required output, available power and operating profile — the stack catalogue comes after those three answers.
PEM electrolyzer stacks and packaged systems sized from output, purity and pressure, with titanium bipolar plates, frames and fittings.
The same four inputs decide every order. This table maps each sector to the medium, the governing failure risk and the parameters an RFQ has to carry.
| Target Industry | Primary Medium | Key Failure Risk | Critical RFQ Parameters |

| Cathodic Protection & Infrastructure | Soil, seawater and concrete electrolytes | Insufficient design current over the protection life | Protection criterion and design current; Environment resistivity and installation conditions; Anode-bed geometry and substrate grade; Cable, connection and continuity requirement |
| Water Treatment & Desalination | Brine, seawater and industrial wastewater | Scaling and fouling on the electrode surface | Feedwater or brine chemistry and impurity load; Production target, flow rate and cell configuration; Current density, efficiency and power basis; Scaling, fouling and gas-release behaviour |

| Mining, Electrowinning & Metals | Hydrometallurgical electrolyte and anolyte | Impurity build-up and uneven current distribution | Electrolyte composition and impurity species; Target metal and current efficiency basis; Anode surface area, spacing and flow arrangement; Impurity control and anolyte management |
| Hydrogen & Energy | Deionised water feed and high-purity hydrogen product | Degradation from start-stop cycling and feed quality | Required hydrogen output, purity and pressure; Available power supply and operating profile; Stack format, cell count and system scale; Balance of plant and safety requirements |

Familiarity with a sector is not the same as an approved order. This section states where that line sits, so the scope of any quotation is unambiguous.
An inquiry becomes a qualified scope through a fixed sequence. The application basis is confirmed first, then the material or coating, then the manufacturing and inspection route. Nothing is committed to a specification until the buyer has approved the basis in writing, and any responsibility not stated in the quotation stays with the buyer or the system integrator.
Some applications carry an approval chain that sits above a normal purchase order. A material certificate is a starting point for those duties, never the approval itself. Each of the sectors below is reviewed case by case before a quotation is issued, and the evidence required is agreed before production starts.
These three groups decide whether a quotation can be prepared. Send what you have — a complete specification is not required for the first review.
What the part has to be, and what it has to be made of.
What the part will actually meet in service.
What has to be proven, and where the boundary sits.
The questions that decide a technical route, answered before a product is named.
Start from the operating condition, not the industry name and not a product code. The medium, the temperature, the current density and the way the part fails in service determine the material and the coating. The industry sector only tells you which of those parameters usually dominates, which is why it is a useful starting point rather than an answer.
There is no default grade for chemical service. Grade 2 is frequently suitable, but the grade has to be confirmed against the actual media, its concentration, the temperature and the oxidising or reducing condition. Chloride content and contamination risk decide the outcome as much as the base metal does.
No. Selecting an industry route narrows the problem to the parameters that usually control it, but it does not confirm material, coating or geometry. Every order still goes through the same technical review, and the material certificate confirms conformity to the stated order basis rather than fitness for the final application.
Include the reaction and electrolyte, the operating current density, the required anode geometry and surface area, the coating type and loading metric with units and measurement method, and the connection requirement. Service life cannot be guaranteed from loading alone, so the operating profile, impurities and shutdown practice have to be stated as well.
Enough to identify the application basis: the medium, the temperature or duty, the dimensions or drawing, the material or coating requirement and the quantity. A complete specification is not required for the first review. Unknown items are identified during technical communication and confirmed before the order is released.
