At the same time, the company operates a variety of products of related iron and hardness of Q295NH weather resistant steel steel enterprises. Annual sales of steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel. The company has obtained hardness of Q295NH weather resistant steel ISO9001:2000 quality system certification, A-level credit unit of the people's Bank of China, and is an excellent supplier of many large state-owned enterprises.
Q345 is a grade of carbon structural steel. Q is the meaning of yield strength, which hardness of Q295NH weather resistant steel is taken from the initial of Chinese Pinyin of "Qu"; 345 is the value of yield point, in MPa. Q345 refers to carbon structural steel with yield point (σ s) of 345mpa. The following letters indicate the quality level, including A, B, C, D and E. Q345 steel has good comprehensive mechanical properties, low temperature performance, good plasticity and weldability. Q345 steel is usually in hot rolling or normalizing state.
Grades hardness of Q295NH weather resistant steel, Q345 (16Mn) and Q390 steel have good comprehensive mechanical properties, good welding performance, cold and hot workability and corrosion resistance. C, D, E grade steel has good low temperature toughness. Mainly used for ships, boilers, pressure vessels, petroleum storage tanks, bridges, power station equipment, lifting and transportation machinery and other higher-load welding structural parts.
Boilers with different parameters, different capacities, and different structures have different hardness of Q295NH weather resistant steel, steel consumption rates. Boilers with small capacity and high steam parameters have high steel consumption. Boilers with low steam parameters mainly use low-carbon steel, while boilers with high parameters use a larger amount of heat-resistant alloy steel, and their cost is much higher. In addition, because the once-through boiler has no steam drum or downcomer, steel consumption has also been reduced.
EN10113 S275M is a technical delivery conditions for thermomechanical rolled weldable fine grain structural steels.S means the structural steel, M means the delivery condition.The EN10113 S275M steel is equivalent to DIN StE285TM,UNI FeE275KGTM. EN10113 S275M steel plate/sheet,EN10113 S275M steel plate/sheet, under EN standard, we can regard hardness of Q295NH weather resistant steel, S275M steel plate/sheet for Fine-grain structural steels, thermomechanically rolled steel.
