Steel Castings - General Technical Delivery Requirements - Third Edition
N 4990
Annotation
This International Standard specifies the general technical delivery requirements for the supply of steel, nickel, and cobalt alloy castings, including the requirements for the selection and preparation of samples and test pieces.
When a material or product standard differ from this delivery specification, the material or product standard shall apply. In the case of investment castings, ISO 16468 will apply.
This International Standard also specifies a group of supplementary requirements which may be applied to steel, nickel, and cobalt alloy castings. These requirements are provided for use when additional testing or inspection is desired and apply only when individually specified by the purchaser.
Автоматический перевод:
Стальные отливки - общие технические нагнетательные требования - третий выпуск
Этот Международный стандарт определяет общие технические нагнетательные требования для поставки стали, никеля и отливок кобальтового сплава, включая требования для выбора и подготовки образцов и опытных образцов.
Когда материал или стандарт продукта будут отличаться от этой нагнетательной спецификации, материал или стандарт продукта должны примениться. В случае литья по выплавляемым моделям применится ISO 16468.
