SS 409 are commonly utilised in automotive exhaust, heat exchanger and fabrication in industries because they have an excellent oxidation resistance, weldability and offer cost-effective performance. The sheet weight can be calculated easily and projects planned with the detailed weight chart in kg and mm.
What is a Stainless Steel 409 Sheet Weight Chart?
A Stainless Steel 409 Sheet Weight Chart in Kg and mm is a reference table that is used to calculate the theoretical weight of sheets as per:
- Thickness (mm)
- Width (mm)
- Length (mm)
- Density of SS 409 (approximately 7.7 g/cm³)
Fabricators, procurement teams, and engineers use this chart to estimate shipping weight, fabrication load, and project costing.
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
A large number of purchasers also demand the Stainless Steel 409 Sheet weight chart in PDF format so that they can easily refer to it during the procurement and site planning.

Chemical Properties of SS 409 Sheets
Chemical properties of SS 409 sheets are largely determined by the quantity of chromium that comprises the material (10.5-11.75%), which gives the material oxidation and resistance to corrosion particularly in high temperature conditions. Being low-carbon (0.08% maximum), controlled manganese and silicon, and iron (iron is the balance) SS 409 is well weldable, has good structural stability and is cost effective. This is the ideal choice in automotive exhaust systems and other industrial purposes, which are sensitive to heat.
The chemical structure of SS 409 assures the corrosion resistance and the stability of the structure.
| Element | Composition (%) |
| Chromium (Cr) | 10.5 – 11.75 |
| Carbon (C) | 0.08 max |
| Manganese (Mn) | 1.00 max |
| Silicon (Si) | 1.00 max |
| Phosphorus (P) | 0.045 max |
| Sulfur (S) | 0.03 max |
| Iron (Fe) | Balance |
Chromium provides corrosion resistance while maintaining good weldability.
Mechanical Properties of SS 409 Sheets
The strength, durability and performance of SS 409 sheets under working conditions is determined by mechanical properties of the sheets of the material. Having a minimum tensile strength of 450 Mpa, yield strength of 205 Mpa and elongation of 22, SS 409 has high structural stability and good formability. Its highest hardness of 183 HB also contributes to moderate use of strength, so it can be used in automotive exhaust systems, heat exchanger, and other high-temperature settings where more balanced mechanical performance is needed.
Mechanical strength is important when selecting material thickness and estimating load-bearing capability.
| Property | Value |
| Tensile Strength | 450 MPa (min) |
| Yield Strength | 205 MPa (min) |
| Elongation | 22% (min) |
| Hardness | 183 HB (max) |
These properties make SS 409 suitable for moderate strength structural and high-temperature applications.
SS 409 Sheet Equivalent Grades
The SS 409 Sheet Equivalent Grades play a part in international sourcing and comparing other standards of materials. Although the main designation can differ depending on the area, the following grades are similar or identical material designations; UNS S40900, EN 1.4512, and DIN X1CrTi12. Such equivalents may be good in checking compatibility, compliance, and easy procurement when using international suppliers and project demands.
Although this page focuses on sheets, equivalent grades are often referenced during global procurement.
| Standard | Equivalent Grade |
| ASTM | A240 |
| ASME | SA 240 |
| UNS | S40900 |
| EN | 1.4512 |
| DIN | X1CrTi12 |
| JIS | SUS 409 |
| Material Type | Ferritic Stainless Steel |
Equivalent grades ensure compatibility in international projects.
Stainless Steel 409 Sheet Dimensional Chart
The Stainless Steel 409 Sheet Dimensional Chart provides the most commonly available thicknesses and their standard widths and lengths that are the best suited to the warehouse to handle, cut, and ship in the industry.

SS 409 Sheet Weight Chart (Kg)
The SS 409 Sheet Weight Chart (Kg) gives the calculated weight of a standard 1000 mm x 2000 mm sheet at various thickness and this way, estimating the material requirements can be estimated faster. The sheet weight increases accordingly with the increase of the thickness between 0.5 mm to 5.0 mm; the weight increases proportionally with the increase in thickness between 7.7 kg to 77.0 kg. This chart assists the engineers, fabricators and buyers to plan the cost of procurement, transportation and project costs efficiently and keep in mind that the actual weight might slightly deviate because of manufacturing tolerances.
