Product Detail
S50C steel plate is a medium-carbon steel that offers a good balance between strength and hardness, making it a reliable choice for applications like molds, mechanical parts, and tools. It’s straightforward to machine, whether you’re cutting or welding, which is why it’s common in industrial use. With the right heat treatment, you can further enhance its strength and wear resistance for more demanding tasks.
Compared to other grades in the same series, S50C has some clear advantages. It’s tougher than higher carbon steels like S55C, which can become brittle, and it offers more strength than lower carbon options like S45C. This makes it a practical option if you’re looking for something with a balanced combination of strength and durability.
Please note that S50C has relatively low corrosion resistance. In humid or corrosive environments, applying a protective coating or plating would be a smart way to prevent rust and extend its lifespan.

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 S50C 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.
