Welding of JIS SM400C plates

Phosphorus is a very harmful element in JIS SM400C plates steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of JIS SM400C plates steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.

Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service.
