Product Introduction

SAE 1055 hot rolled carbon steel require high strength and durability. This grade of carbon steel is commonly produced by hot rolling, which involves heating the steel to a high temperature and then rolling it to the desired thickness and shape. Hot rolling improves the properties of the steel by increasing its strength, toughness, and ductility. SAE 1055 is often used for parts that need to withstand high stress and wear, such as automotive components and industrial machinery.

The product specifications for SAE 1055 hot rolled carbon steel are as follows:

The chemical composition of carbon (C) content is 0.52 0.60%, manganese (Mn) content is 0.60 0.90%, phosphorus (P) content of 0.040% or less, sulphur (S) content of 0.050% or less.
Physical properties: With high strength, high toughness and excellent total expansion and impact toughness and other physical properties, suitable for a wide range of machining applications.
Surface state: smooth and flat surface, no obvious defects and defects.
Size range: Wide range of sizes, can supply a variety of different shapes and sizes of steel to meet a variety of application needs.
