With consistent quality, precise dimensions, and multiple finishing options, AISI 1045 Carbon Steel Round Bars are suitable for both structural and mechanical uses.
What is AISI 1045 Carbon Steel?
AISI 1045 is a medium-carbon steel grade containing approximately 0.45% carbon, which gives it higher strength and hardness than low-carbon steels while still maintaining good ductility.
It is commonly referred to as:
- AISI/SAE 1045
- Carbon Steel AISI G10450 Bar
- UNS G10450
- DIN 1.1191
Because of its mechanical strength and ability to be heat-treated, AISI 1045 Bars are used in components that experience moderate to high stress.
Key Benefits of Carbon Steel AISI 1045 Round Bars
From our real-world supply experience, customers prefer AISI 1045 Round Bar for applications where both strength and machinability are important.
- High tensile and yield strength
- Good wear resistance
