Product Detail
S45C steel plate is a medium carbon steel that’s commonly used in machinery and mold making. It offers good hardness and strength, making it suitable for handling pressure and wear. Once heat treated, it improves in toughness and wear resistance, which is why it’s often used for parts like shafts and gears. It’s also relatively easy to machine, especially before heat treatment, and can be welded or cut as needed. The pricing is reasonable, so it offers a good balance between cost and performance, making it a reliable choice for many industrial applications.

Why Choose Us
Consistent Quality
Common issues you may concern, such as surface defects, uneven hardness, and internal stress, can affect performance. We employ methods such as improved heat treatment, sandblasting, and acid pickling to ensure a flawless surface; optimized uniform heat treatment and annealing for consistent hardness; and controlled slow cooling, segmented cooling, and low-temperature tempering to release internal stress.
Precise Dimensions
We guarantee the dimensional accuracy of our S45C plates in accordance with international standards. We can maintain tight tolerances up to ±0.01 mm through precision equipment and ISO 9001-certified processes. Every batch undergoes 100% inspection, with zero deviation complaints in the past 5 years. We ensure smooth project execution without installation delays.
Stable Supply
We have 3 factories with a combined annual capacity of over 500,000 tons. In the event of any unforeseen circumstances, we can coordinate across factories to ensure stable production and on-time delivery.
