ASTM A519 Grade 1045 seamless stainless steel tube is a medium carbon steel mechanical tubing known for its higher strength, hardness, and wear resistance compared to lower carbon grades. With a carbon content of approximately 0.45%, Grade 1045 offers an excellent balance of strength and toughness, making it ideal for components subjected to high stress and dynamic loads. It is widely used in applications requiring good machinability combined with improved mechanical properties.
Key Features:
1) Higher strength and hardness than low carbon steel grades
2) Good wear resistance and durability
3) Excellent machinability
4) Available in versatile conditions: HR, CW, SR, A, and N
