hot-rolled steel plate

Carbon steel is an iron-carbon alloy with carbon content ranging from 0.0218% to 2.11%. Also known as carbon steel. Generally also contains a small amount of silicon, manganese, sulfur, phosphorus. The higher the carbon content of general carbon steel, the greater the hardness, the higher the strength, but the lower the plasticity.

Frequently Asked Questions

Q: What thickness tolerances do you provide for heavy plates?

A: We strictly adhere to ASTM A6 and EN 10029 Class B/C. Typical tolerances range from +/- 0.3mm to 0.8mm depending on thickness. We use high-precision leveling machines to ensure optimal flatness for laser/flame cutting.

Q: How do you ensure the quality of extra-thick (100mm+) plates?

A: For engineering projects requiring heavy plates up to 200mm, we perform Ultrasonic Testing (UT) as per ASTM A435/A578 to verify internal soundness and prevent lamination issues during subsequent fabrication.
