A633Gr.D as-rolled material prices continue to be weak and downward

The company adheres to green development, supported by scientific and technological innovation and technological progress, vigorously advocates the A633Gr.D as-rolled material production and life style of saving, environmental protection, civilization and low carbon, adheres to the new industrialization road and the sustainable development road. Actively carry out international trade and maintain stable economic and trade relations with more than 80 countries and regions including the United States, Germany, France, the United Kingdom, Japan, South Korea and Australia.

Low alloy steel plate was originally developed for large diameter oil and gas pipeline in 1960s. Pipeline steel materials used in oil and gas projects require higher strength and toughness than low carbon steel, and have good weldability just the same as low carbon steel.Advantages: A633Gr.D as-rolled material, Low alloy steel plate has superior performance and light weight.Disadvantages: Low alloy steel plate is killed steel, so the price will be more expensive.

The alloy steel seamless pipe is a kind of product developed on the basis of traditional seamless steel pipe. Some characteristics of the A633Gr.D as-rolled material, alloy steel seamless pipe are also great progress and optimization based on the traditional seamless steel pipe products. Alloy steel seamless pipe is a kind of high performance seamless pipe. In industrial production, seamless pipe is usually used in pipeline engineering which needs to bear greater pressure.

The effect of nitrogen (N) on the properties of A633Gr.D as-rolled material and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in A633Gr.D as-rolled material and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.

NM500 wear plate is Chinese abrasion resitant steel. NM500 steel is equivalent to AR500, HARDOX500, XAR500 and so on materials. The surface Brinell hardness of NM500 wear plate is ≥470 HBW. The NM500 steel is consists of max. 0.38% Carbon, 0.70 Silicon, 1.70 Manganese, 0.020 Phosphorus, 0.010 Sulfur, 1.20 Chrome, 1.00 Nickel, 0.65 Molybdenum, 0.050 Titanium, 0.0005-0.006 Boron, min. 0.010 Als, etc.. According to GBT24186, the max. thickness of A633Gr.D as-rolled material, NM500 wear plate is 70mm.
