GRADE + FINAL CONDITION
The right material depends on how your part is made and used. Discuss magnetic response, corrosion, strength, forming and surface needs alongside the grade and final condition.
If your part needs low magnetic response after forming or welding, share the final use and processing plan with us. We review the material condition, permeability requirement and inspection criteria together with the relevant material and processing partners.
Low magnetic response is defined by the agreed magnetic permeability and inspection criteria for the finished part. The grade and delivery condition matter, and cold working or welding can change the response. Selecting a grade alone does not ensure that the material will meet the magnetic requirement after processing.
Austenitic stainless steels generally have low magnetic response in the solution-annealed condition. Ferritic and martensitic grades, and the ferritic phase in duplex grades, are magnetic. Specify the exact grade and heat-treatment condition rather than relying on a series name or a general hard or soft label.
Cold working can form magnetic martensite in some austenitic grades. Rolling, drawing, bending and stamping therefore need to be considered alongside welding and later heat treatment. Describe the complete route for your part; magnetic response alone is not a method of identifying its grade.
List the cold rolling, drawing, bending, stamping, machining, welding or heat treatment planned for your part. Identify the final condition in which the magnetic requirement needs to be met.
A specified relative permeability limit and measurement method help define the request. Include inspection locations, local thickness and geometry, and any drawing or customer specification.
We review the inspection stage, sampling and report requirements with the material and processing route. These criteria are agreed for the order.
No. Austenitic grades are relevant to low-permeability applications, but their magnetic response can change with processing. The specific grade, final condition and acceptance criteria need to be considered together.
It means the condition after the operations that matter for your part. List the planned forming, drawing, welding and heat-treatment steps, and identify when the magnetic requirement will be inspected.
You can select “Non-magnetic after processing” in the product options and add the processing route, target permeability and inspection requirements. A drawing can identify the areas to be assessed; you can also attach it directly to an enquiry.
Provide the required limit and test specification. WANRONG METAL coordinates the review with the relevant material and processing partners; the agreed inspection scope and documents are recorded for the order.
A grade needs to suit the environment your finished part will face. We review exposure, fabrication and surface requirements together when discussing corrosion performance.
Indoor or outdoor use, contact media, chlorides, chemicals, temperature and cleaning conditions help define the exposure your material needs to handle.
Welds, formed edges and joints can affect the finished component. A drawing and any specified corrosion test or inspection criteria help us review the material request.
The material condition needs to suit both forming and the strength required in service. Compare the planned processing, part geometry and tolerances alongside the properties specified for delivery and the finished part.
Any tensile strength, yield strength, elongation or hardness requirements from your specification can be included with the material condition, standard and inspection documents.
A drawing or process description can cover rolling, drawing, stamping, bending, machining, welding and later heat treatment. Include thickness, bend details and the final inspection condition.
Your part may need a particular appearance, cleaning response or functional surface. We discuss the substrate and base finish with PVD, functional topcoat or decorative film options for that use.
An appearance sample can show colour, gloss, texture and grain direction. Tell us which faces are visible and how the finished surface will be handled and cleaned.
Forming, cut edges and inspection are considered with the finished surface. Removable transport or processing film is specified separately from decorative film and functional topcoats.
Explore product forms for the material you need. Each detail page shows sizes, finishes and processing options, with a short enquiry form for your drawing or existing requirements.
Your component drawing, specification or purchasing list helps us discuss the material you need. Include any known grade, product form, dimensions and delivery condition, along with the required standard, inspection and documents.
The grade, size combination and delivery requirements are confirmed together for your order.
Send a drawing, purchasing list or a brief description of the part you are making. Share any grade, dimensions, quantity and destination you already know; we can discuss the remaining material requirements with you.
