1045 – Steel
Increased Strength and Impact with 1045 Steel
Carbon steel has become one of the most widely used materials in the world, and this is thanks in large part to the 1018 and 1045 steels. Luckily, our deep inventory will meet whatever needs you may have, and our Sure Bar™ promise guarantees that our products are of the highest quality.
With its higher carbon content and increased tensile strength, 1045 is a much stronger steel than 1018, which is why it is so often used in applications that require more strength than 1018 offers, such as in transmission parts. However, that strength comes with its own limitations. While 1045 still offers good weldability, its higher carbon composition makes this process a little more difficult. On thinner sections, this steel readily offers weldability, but thicker sections will require preheating.
1045 is commonly stress relieved, normalized, or annealed after being flame cut to size for easier machining. This material responds well to heat treatment, and the resulting mechanical properties allow for numerous applications in the production of machinery parts.
