Manufacturer typical composition, mass %; selected elements only.
These published alloy values are comparison data. The IS 6911 acceptance limits must be checked in the specified revision.
| Grade / identification | Product form / condition | Tensile (MPa) | 0.2% proof / yield (MPa) | Elongation (%) | Data basis |
|---|---|---|---|---|---|
| SS304 S30400 | Hot-rolled plate, usually 10–20 mm, transverse; room temperature | 600 | 270 | 55 | Manufacturer typical values; elongation A5. |
| SS316 S31600 | Hot-rolled plate, usually 10–20 mm, transverse; room temperature | 570 | 260 | 55 | Manufacturer typical values; elongation A5. |
| SS316L S31603 | Hot-rolled plate, usually 10–20 mm, transverse; room temperature | 570 | 260 | 55 | Manufacturer typical values; elongation A5. |
Typical properties are comparison values. Manufacturer limits marked “min” apply only to the stated product. Confirm the ordered revision, thickness, heat treatment, specimen direction and gauge length before material acceptance.
Engineered for demanding service.
Grade selection depends on the process environment, temperature, corrosion exposure and equipment design.
From material specification to gasket construction
Select the required product form, grade, delivery condition and certification for the approved gasket construction. Finished gasket dimensions and performance requirements are established separately.

Short answers for engineers and purchasing teams.
How should IS 6911 be specified?
State the revision, exact material grade, product form, dimensions, delivery condition and certification requirements on the purchase order.
Are the displayed properties specification acceptance limits?
The tables identify published manufacturer reference data. Typical values describe the stated reference product and are not certified IS 6911 limits. Use the ordered revision for material acceptance.
Are these all the materials covered by the standard?
This page links selected materials already present on the website. The linked material list is not the complete scope of the standard.
