NACE Carbon Steel: Understanding ISO 15156-2 Annex A.2.1.4

Introduction

Are you confused about the definition of “”carbon manganese steel”” in ISO 15156-2 Annex A.2.1.4? You’re not alone. In this article, we’ll provide a simple question-and-answer format to help clarify this important topic.

What Is Carbon Manganese Steel?

Carbon manganese steel is not explicitly defined in ISO 15156-1, which can make it difficult to understand. However, the definition of carbon steel can be used as a guide. Carbon steel includes alloys that can contain up to 1.65 mass percent Mn, which means that carbon manganese steel can be inferred from this definition.

Will There Be Changes to the Definition?

While there may be discussions to provide a separate definition or enhance the definition in ISO 15156-1, any suggested changes will require a technical ballot. This means that the definition of carbon manganese steel will remain the same for the foreseeable future.
