Product Forms and Processing Matrix
Depending on the material and source route, special engineering alloy enquiries may involve raw material, semi-finished forms or drawing-based components.
| Requirement type | Common forms | Processing details to define |
|---|---|---|
| Flat products | Sheets, plates, strips, coils, flats and shims | Thickness, width, length, temper, finish, tolerance and cutting. |
| Long products | Round bars, rods, hex bars, square bars, wires and profiles | Diameter, length, straightness, condition, hardness and machining allowance. |
| Tubular products | Pipes, tubes and hollow bars | OD, ID, wall thickness, schedule, length, standard and testing. |
| Forged or cast items | Forgings, castings, blocks, rings and discs | Drawing, heat treatment, machining, NDT and inspection. |
| Finished components | Fasteners, washers, machined parts and custom items | Drawing, tolerances, surface finish, quantity, inspection and packing. |
Hard-to-Source and Project-Specific Metal Grades
Some enquiries start with an old drawing, plant maintenance requirement, import substitution request, trade name, obsolete grade or project-approved material list. For these cases, Rubinox reviews the enquiry against the specification, equivalent permission, application, documentation requirement and feasible source route. Buyers should share drawings, datasheets, previous purchase descriptions, chemistry, mechanical properties or approved vendor notes where available.
Material Identification Checklist
When the exact grade is uncertain, send every available clue before requesting a quote: trade name, stamped marking, old invoice, mill certificate, drawing note, chemical composition, hardness, magnet response, application, operating temperature, media exposure, current failure issue and any approved equivalent grades. This helps avoid mismatched material recommendations.
Product Forms & Processing
Enquiries may cover sheets, plates, strips, coils, pipes, tubes, round bars, rods, wires, flats, profiles, forgings, cast products, fasteners or machined components. If cutting, machining, heat treatment, surface finish or fabrication is required, attach a drawing and define tolerances before quotation.
Wear and Abrasion Applications
Special engineering alloys may be reviewed for wear plates, liners, bushes, shafts, rollers, dies, tooling, bearing components and sliding parts. Share the wear mode, hardness target, impact load, surface finish, dimensions and drawing so the enquiry can be checked properly.
Heat and High-Temperature Applications
Heat-related enquiries may involve heat treatment fixtures, furnace components, thermal processing parts, high-temperature fasteners and tooling. Buyers should mention operating temperature, atmosphere, thermal cycling, load, grade, standard and inspection needs.
Electrical and Conductivity Applications
Non-ferrous special alloy enquiries may involve copper alloys, specialty bronze, tin, zinc and conductive components such as contacts, connectors, bus parts and electrical hardware. Include conductivity requirement, temper, dimensions, finish and inspection scope.
Chemical and Corrosion-Resistant Applications
For chemical, marine, plating or corrosion-related service, share media, concentration, temperature, pressure, pH, chloride level and standard. Buyers should also review focused pages for Nickel Alloys, SMO 254, Duplex and Titanium when those grades are specified.
Standards, Trade Names and Equivalents Guidance
For special alloy enquiries, provide at least one formal reference such as ASTM, ASME, EN, DIN, JIS, IS, UNS, AISI, SAE, a manufacturer datasheet, chemical composition, drawing or approved material list. Trade names can help identify the intended material, but Rubinox does not assume automatic equivalence. Any substitute or equivalent grade should be approved by the buyer, project engineer or end user before procurement.
