The "Yield Point Control Steel Plate" maximizes the use of its unique electric furnace thick plate manufacturing line for small-lot, diverse product manufacturing technology, reducing variations in yield point through fine-tuning of component ratios for each product thickness and special rolling. The standard range for the yield point has been narrowed to about one-third of the range of JIS standard SN steel materials. By using this product in steel braces, which are one type of vibration control device, design goals can be easily achieved. 【Features】 ■ Small variation in yield point (upper and lower limits of product specifications are 50 N/mm²) ■ Excellent weldability ■ Capable of short delivery times For more details, please refer to the catalog or feel free to contact us.
