ASTM 1045/45# Carbon Steel Coils - High-Strength Precision Steel for Machinery Components Manufacturing

Product Description

ASTM 1045 / 45# Carbon Steel Coils are a premium-grade medium carbon steel engineered for durability and high mechanical performance. With its balanced combination of strength, toughness, and wear resistance, this material is ideal for machinery manufacturing where both precision and reliability are critical.

Its surface has a clean, dark metallic luster that conveys industrial strength. Once processed, it maintains a solid, dense feel—making every component machined from it reliable and robust. Whether shaped into drive shafts, gears, axles, or forged parts, 1045 steel is a material that brings peace of mind to manufacturers seeking consistency across production batches.
