Ship and marine technology — High-manganese austenitic steel — Specification for high-manganese austenitic steel welded fittings for cryogenic temperature

Navires et technologie maritime — Acier austénitique à haute teneur en manganèse — Spécification pour les raccords soudés en acier austénitique à haute teneur en manganèse pour température cryogénique

Abstract / scope

This document provides requirements for wrought high-manganese austenitic steel welded fittings used for pressure piping at cryogenic temperature.

The specification of high-manganese austenitic steel welded fittings is applicable to all pressure retaining components and any non-pressure retaining components used in hull systems for marine technology and in onshore projects.
