Naing Steel, a trusted manufacturer and supplier based in Naypyidaw, is proud to offer high-quality SAE 1045 steel sheet and plate to industries across Myanmar. We understand that the backbone of any strong project is reliable materials, which is why our 1045 steel is produced with meticulous attention to detail. This medium carbon steel is an excellent choice for applications demanding a superior combination of strength, durability, and wear resistance, providing a solid foundation for your most demanding fabrication and construction needs.
The composition of SAE 1045 is straightforward yet effective, centered around a medium carbon content of approximately 0.45%. This key element is balanced with manganese to create a material known for its robust mechanical profile. After proper heat treatment, it achieves a notable increase in hardness and tensile strength while maintaining good machinability in the annealed state. This balance makes it a versatile workhorse, capable of being forged or shaped into high-strength components.
