Today, the trend of black futures remained high, and the spot market price continued to rise. However, after the rise, the overall turnover of the market weakened compared with the previous trading day, and the transaction of low-cost resources was acceptable. In terms of steel mills, the output of steel mills continues to be high, with firm ex factory prices and relatively saturated orders. s 45 c sa36 S235JR mild steel sheet traders are reluctant to sell at a low price due to the high cost of taking goods, which will support the s 45 c sa36 S235JR mild steel sheet price in the short term. It is expected that s 45 c sa36 S235JR mild steel sheet prices will maintain a high consolidation trend tomorrow.

As the thickness and hardness of s 45 c sa36 S235JR mild steel sheet increase, the tendency to crack at the cutting edge increases. In order to prevent the s 45 c sa36 S235JR mild steel sheet from cutting cracks, preheating should be carried out before s 45 c sa36 S235JR mild steel sheet cutting. Special attention should be paid to preheating to make the entire s 45 c sa36 S235JR mild steel sheet interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole s 45 c sa36 S235JR mild steel sheet cannot be preheated, the partial preheating method can be used instead.
