Heat Treatment
ISO 185–2020
Heat treatment is subject to agreement. Castings not ordered with heat treatment specified shall not be heat-treated unless agreed by the purchaser before shipment (10.4).. Only if ordered with heat treatment specified or subsequently agreed by purchaser before shipment; no temperature/cycle invented.; If castings are heat-treated, representative samples shall be heat-treated in the same way.

ISO 185 — 2020 · Table 1 — Normative
| Property | Cast-on samples | Separately cast or side-by-side cast samples |
|---|---|---|
| Tensile Strength | ≥ 125 MPa[1] ≥ 110 MPa[2] ≥ 100 MPa[3] ≥ 90 MPa[4] | 150–250 MPa[5] 150–250 MPa[6] 150–250 MPa[7] 150–250 MPa[1] 150–250 MPa[2] 150–250 MPa[3] 150–250 MPa[4] |
- Cast-on samples: Cast-on sample, type and representative wall thickness agreed with purchaser; Mandatory Table 1 cast-on sample minimum; sample type, size, position and relevant wall thickness agreed. Source shared boundaries retained; no exclusive boundary inferred.
- Separately cast or side-by-side cast samples: Separately cast or side-by-side cast sample; grade relates to 30 mm as-cast sample; Table 1 lower/upper headings are >= and <=, retained verbatim. Shared exact boundaries are not reassigned. Sand moulds or moulds with comparable thermal behaviour; other methods require agreement.
