77.140.80 - Iron and steel castings

This document specifies the requirements for the ultrasonic testing of steel castings (with ferritic structure) for general purposes, and the methods for determining internal discontinuities by the pulse-echo technique. This document applies to the ultrasonic testing of steel castings which have usually received a grain-refining heat treatment and which have wall thicknesses up to and including 600 mm. For greater wall thicknesses, special agreements apply with respect to the test procedure and ...view more

This document specifies the requirements for the ultrasonic testing of steel castings (with ferritic structure) for highly stressed components, and the methods for determining internal discontinuities by the pulse-echo technique. Purchasers determine if components are highly stressed based on the need for performance or safety. This document applies to the ultrasonic testing of steel castings which have usually received a grain-refining heat treatment and which have wall thicknesses up to and in...view more

This document specifies the acceptance criteria for the surface examination of steel, nickel alloy and cobalt alloy investment castings by visual testing.

This document specifies a method for the magnetic particle testing of ferro-magnetic steel and iron castings. It also gives acceptance criteria through severity levels defined by the nature, the area and the dimensions of the discontinuities present. This document is applicable to all ferro-magnetic castings, independent of the moulding method. A steel and iron casting is considered to be ferro-magnetic if the magnetic induction is greater than 1 T (Tesla) for a magnetic field strength of 2,4 kA...view more

This document specifies a method for the liquid penetrant testing of steel castings.

1.1 This document covers the acceptance criteria for the visual testing of the surface of steel and iron castings. 1.2 Acceptance levels utilize Bureau de Normalisation des Industries de la Fonderie (BNIF) and Steel Castings Research and Trade Association (SCRATA) or Casting Technology International (CTI) reference comparators for the visual determination of surface roughness and surface discontinuities described as follows: — surface roughness; — thermal dressing; — mechanical dressing; — non-m...view more

This document specifies the requirements for the radiographic inspection of castings for aerospace applications.
It shall be applied when referred to in the EN technical specification or material standard unless otherwise specified on the drawing, order or inspection schedule.

This document specifies tool steel compositions for castings. NOTE Annex A gives information on ISO grade designation and available UNS numbers which are similar to the ISO grade designation.

ISO 13520:2015 specifies procedures which are covered for estimating ferrite content in certain grades of austenitic iron-chromium-nickel alloy castings that have compositions balanced to create the formation of ferrite as a second phase in amounts controlled within specified limits. Methods are described for estimating ferrite content by chemical, magnetic and metallographic means.

This document applies to corrosion resistant steel castings for general purposes.
This document relates to castings manufactured from martensitic, austenitic, fully austenitic and
austenitic-ferritic steel grades characterized by their chemical composition (see Table 1) and mechanical properties (see Table 2).
ln cases where castings are joined by welding by the founder, this document applies.

This European Standard describes techniques and acceptance criteria to be used for the magnetic particle testing of forgings manufactured from ferromagnetic materials. The method described is used for the detection of surface discontinuities. It can also detect discontinuities just below the surface but the sensitivity to such discontinuities decreases rapidly with depth.

This International Standard specifies requirements for classification of covered electrodes for manual
metal arc welding, wire electrodes for metal arc welding, tubular cored electrodes for metal arc welding
with and without a gas shield, rods for TIG-welding, and rods for oxy-fuel gas welding of unalloyed cast
irons. Classification is based on the chemical composition of wires and rods and on the all-weld metal
deposit for tubular cored and covered electrodes.
