A36 Steel Chemical CompositionĪ36 is low carbon steel, and as such has a carbon content of less than 0.3% (by weight). One such material is A36 steel, which is one of the most common metals used for structural purposes. For most types of steel, the chemical composition is what determines the grading. What Is A36 Steel?ĪSTM International (American Society for Testing and Materials) is a standards organization that regulates the standards of a huge range of materials, systems, services, and products all over the world. Keep reading to see why A36 steel might be the perfect choice for you. This article will provide an overview of A36 steel, which is one of the most common types of steel on the market. When planning a project, choosing the correct materials is essential. Steel is an alloy of carbon and iron, but there are many different types with many different uses. Over the years, steel has quickly become one of the most common materials for structural applications. In 2020, the global steel plate market reached a value of $53.9 billion and is expected to grow to $65 billion by 2026.
