How to effectively prevent the NM450 steel grade from welding cracks and deformation

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 NM450 steel grade 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 NM450 steel grade etc. steel is strictly controlled.

Japan's crude steel production is expected to fall 25.9% in the April June quarter from a year earlier, the Ministry of Economy, Trade and Industry said Thursday. The Ministry of Economy and Industry quoted an industry survey report as saying that the demand for NM450 steel grade and so on steel products (including export products) in April June is expected to drop 18.1% to 18.28 million tons from the same period last year. At the same time, steel exports in the current quarter will decline by 21.4% year-on-year.
