This 304L stainless steel end is manufactured in accordance with DIN28011.

The dish radius is 450mm. 

The knuckle radius is 45mm.

The straight flange height is 25mm.

304L - 1.4307 stainless steel

This dished head is made from stainless steel sheet 304L - 1.4307 in 3 mm thickness.

The 304L is the most popular stainless steel. Also called 1.4307, it is a food-compatible stainless steel.

The origin of stainless steel sheets (used for the manufacture of heads) is European and our partners are ISO9001 certified manufacturers from France.

Manufacturing standards of dished heads

These bottoms are manufactured in accordance with DIN28011. Manufacturing tolerances strictly follow the DIN28011, highlighting the tolerances on its height, its thickness after forming.

For a tank bottom ordered at a nominal thickness (also called starting thickness) E, the actual thickness measured after forming may differ from E, not only because of the tolerances on the thickness of the sheet, but also because of changes caused by the forming process.

Torispherical head forming processes

Dished heads are manufactured by cold processes, spinning or press-forming.

All our dished stainless steel are supplied without grease. No heat treatment is performed after forming.

The 450mm diameter head with  a 3mm thickness is made from a disc without weld.
