Overview
441 enquiries must identify UNS S44100 or the intended EN route; similarly named 441/4509 materials are not combined into one composition. Use the component geometry and service conditions to select the product form before asking for dimensions, processing and inspection.
Send the grade, standard, product form, dimensions, quantity and inspection scope; we will match the available mill and processing route in your quotation. Your engineering team retains approval of the material selection for the application.
Standards & Designations
- Type 441 / UNS S44100
- EN 1.4509 as a composition-route reference only
Treat these published names as routes into the governing product standard, not as automatic substitutes for one another. State the selected designation, complete product standard, edition and any purchaser specification in the enquiry and purchase description.
Chemical Composition
State the grade and product-standard edition in the purchase description. The chemical limits can then be checked against the heat-specific MTC for the supplied material.
Mechanical Properties
Define required properties, test orientation, thickness applicability, heat-treatment condition and acceptance criteria from the ordered product standard and project specification. The MTC reports the applicable results for the supplied heat.
Physical Properties
Use physical-property data for the exact grade route and condition in your design. Tell us which designation, product form and delivery condition the project uses when requesting supporting technical documents.
High-Temperature Characteristics
Compare the material against the actual temperature profile, atmosphere, pressure or load, cycling, deposits, fabrication route and design code. Share those inputs when you want our team to help organize the grade and supply-route review.
Available Product Forms
Choose the form that fits the component geometry and fabrication plan, then use its product page to prepare dimensions, finish, processing, inspection and packing requirements.
Available Dimensions
Open the linked product-form pages to compare available dimensions. Include the exact grade, standard, dimensions, quantity and inspection scope so the mill and processing route can be matched in the quotation.

Processing & Welding
Share the drawing, delivery condition, forming route, joint design, filler requirements, WPS/PQR, heat input, cleaning or passivation and NDT scope. Drawing geometry and the ordered standard help the fabricator prepare the process route and qualified procedure.
Application Review
Use the following industry pages to organize service conditions, component requirements and the documents needed for a Project Solution enquiry.
Inspection Options
- MTC identifying the heat, grade route, ordered standard and reported test results.
- Dimensional, surface, traceability and marking records specified by the purchase order.
- NDT, PMI, third-party inspection or additional test reports only when ordered.
- EN 10204 3.1 wording only when the issued certificate explicitly carries that type.
Related Grades
Compare grade families, product routes and service inputs before requesting an alternative. Any substitution requires review against the governing standard, design basis and project approval process.
What to Send for a Quote
Include the exact grade designation, governing product standard and edition, product form, dimensions, condition, quantity, service inputs, inspection scope, certificate type, packing and destination.
