Require a reference for a good Stainless Steel 409M sheet? The following guide includes all the details of this sheet, including the SS 409M Sheet Weight Chart, dimensional specifications, chemical composition, mechanical properties, and ASTM A240 tolerances. It is created to assist engineers, fabricators, and industrial purchasers to know how to compute material requirements, price, and logistics.
Stainless Steel 409M Sheet is employed in auto exhausts, ducting in industries, and in high-temperature structural applications because it has high levels of corrosion resistance, thermal stability and a titanium-stabilised ferritic structure. The comprehensive weight chart in kg and mm makes the project planning and estimation of materials easier.
What is a Stainless Steel 409M Sheet Weight Chart?
A Stainless Steel 409M Sheet weight Chart in Kg and mm is a record sheet used to find the theoretical weight of the sheets depending on:
- Thickness (mm)
- Width (mm)
- Length (mm)
- Density of SS 409M (approximately 7.7 g/cm³)
This chart is applied by fabricators, procurement teams, and engineers in order to estimate shipping weight, fabrication load, and costing of the project.
The general formula used for calculation is:
Weight (kg)=Length (m)×Width (m)×Thickness (mm)×7.7
Weight (kg)=Length (m)×Width (m)×Thickness (mm)×7.7
Many buyers also request the Stainless Steel 409M Sheet weight chart in PDF format for quick reference during procurement and site planning.

| Element | Composition (%) |
| Chromium (Cr) | 10.5 – 11.75 |
| Titanium (Ti) | 0.25 – 0.60 |
| Carbon (C) | 0.08 max |
| Manganese (Mn) | 1.00 max |
| Silicon (Si) | 1.00 max |
| Phosphorus (P) | 0.045 max |
