A bowl forging is a closed-bottom hollow shape - a cavity sunk into a solid billet rather than a ring rolled open. The bottom stays integral, so there is no weld across the base and the grain wraps the cavity wall.
There is no standard behind the shape. OD, cavity depth, wall profile, bottom radius and machining allowance all come from the drawing, with the material grade taken from the ASTM or EN standard you cite. Feasibility is checked against the forging route, the heat-treatment capacity and the machining envelope.
Typical parts are pressure equipment components, custom housings, heavy machinery blanks and formed blanks for later machining. Wall thickness and bottom radius drive both forgeability and the amount of stock that has to be left on, so both need to be on the drawing before a price means anything. Inspection is UT, a dimensional report, hardness, the heat-treatment record and a surface check.

We confirm each step against your drawing or standard before we quote.
Material grade, heat number, certificate basis and substitution limits are checked against the Bowl Forgings drawing or standard before procurement is released.
The forging route is selected around the drawing shape, section changes, forming direction, stock allowance and final machining datum scheme.
Heat treatment is planned with the required record package, mechanical testing basis and impact-test condition where low-temperature or alloy service applies.
Rough machining establishes the drawing datums and reference faces needed to control allowance before the final contour or bore work starts.
Final machining controls the drawing datums, bores, profiles, faces and critical tolerances defined by the buyer's revision-controlled drawing.
Inspection covers dimensional report, MTC 3.1, PMI and required UT, MT or PT records before the release documents are matched to the purchase order.
Marking, packing and export documents are prepared by PO line item so the Bowl Forgings shipment can clear customs and be identified at site receiving.
