thickness of steel nm450 Price in Portugal 2021

thickness of steel NM450, High strength NM400 wear-resistant plate is mainly used in mining, engineering machinery, strong wear and other environmental parts; open-pit shovel teeth, bucket teeth, excavator factory supporting shovel teeth; vehicles, hydraulic equipment, transmission equipment, high-strength standard parts, etc. Specifications of stock wear-resistant plate, thickness of steel NM450: 10 x2000 x8000, 12 x2000 x8000, 14 x2000 x8000, 16 x2000 x8000, 18 x2200 x8000, 20 x2200 x10000, 25 x200 x8000, 30 x2500 x10000, 35 x2200 x8000.

In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This thickness of steel NM450 production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate thickness of steel NM450 size.

As the basic processing materials and building materials, the medium and heavy plate is an important purchasing material for many manufacturers and construction enterprises, so the grasp of the latest price rise and fall of the medium and heavy plate, thickness of steel NM450 is directly related to the cost and profit of enterprises. Therefore, it is necessary for purchasing staff to learn how to predict. Today, we share the latest price rise and fall skills, how to predict the price trend of medium and heavy plate, thickness of steel NM450.

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 thickness of steel NM450 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 thickness of steel NM450 etc. steel is strictly controlled.
