SM520 is a low - carbon high - strength structural steel plate used for welded structures, featuring good cold - forming properties. Here is an introduction to its factory price and other aspects:

Factory Price

General Price Range: The factory price of SM520 low - carbon steel plates varies by region, manufacturer, order quantity, and plate thickness. Generally, the price per ton is between $350 and $12003. For example, on Alibaba.com, the price range is $405 - $445.5 per ton for orders of 1 ton, and $540 - $630 per ton for orders of 1 ton on some Chinese factory websites3. On the other hand, the price is $785 - $820 per ton for orders of 1 ton on certain Japanese factory websites3.
