Why is the price of equivalent material of nm500 steel high even with high yield low demand

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 equivalent material of NM500 steel 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 equivalent material of NM500 steel 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 equivalent material of NM500 steel BBN Group various activities that record the company's beautiful memories in recent years. Among them are photos of the equivalent material of NM500 steel 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. The BBN steel company has rich staff activities and pleasant staff life.

The weldability of equivalent material of NM500 steel is good. It means that under certain process and construction conditions, equivalent material of NM500 steel can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.
