Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of S420ML steel supplier etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in S420ML steel supplier etc. steel is strictly controlled.

In 2019, our company has decorated the office building for newlook. We also make the cultural wall with various photos. These photos are a combination of S420ML steel supplier BBN Group various activities that record the company's beautiful memories in recent years. Among them are photos of the S420ML steel supplier company's annual meeting, photos of group trips, pictures of factories, party pictures, photos of outdoors organized barbecues, photos of winter sports, pictures of table tennis matches.
