Influence factors of copper brittleness defects in ASME SA572 carbon steel plate sheet

In 2019, the output of pig iron in the world was 1.265 billion tons, with China accounting for 64%; the overseas output accounted for 36% (460 million tons), ranking 86.982 million tons of EU 28 countries, 74.907 million tons of Japan, 74.099 million tons of India, 73.264 million tons of CIS, and ASME SA572 carbon steel plate sheet 47.521 million tons of South Korea. In the first quarter, the global output was 311 million tons, with a year-on-year decrease of 0.5%, with China ASME SA572 carbon steel plate sheet increasing by 2.4%; the overseas output decreased by 5.4%, Among them, EU decreased by 9.2%, Japan increased by 1.3%, India decreased by 7.7%, CIS increased by 2.1%, and South Korea decreased by 4%.

BBN company team and culture: tt the end of 2019, in order to thank employees for their hard work and enrich their sparetime lives, the company organized a pleasant trip to Phuket Island, Thailand. This tour lasted 6 days and 5 nights, and returned by plane on the evening of December 27. We took off in Zhengzhou at about 5o'clock in the afternoon on the 22th December. Let's seize the day and live it to the full, and greet the arrival of the year 2020 together.

The difference between Q235 steel and Q345 steel:The lower limit of yield strength of Q235 steel is 235MPa, the lower limit of yield strength of Q345 steel is 345MPa. The ASME SA572 carbon steel plate sheet alloy content of Q235 steel is common carbon steel and Q345 steel is low alloy steel. Q345 steel is used for structures, mechanical parts, building structures, general metal structures bearing dynamic loads such as medium and low pressure vessels, oil tanks, vehicles, cranes, ASME SA572 carbon steel plate sheet mining machinery, power stations, bridges, etc..

A36 is American Standard ASTM material, SS400 is Japanese Standard JIS g3101 steel material for general structure, Q235 is Chinese standard GB700 material. The limitation of the content of the Mn element differs depending on the thickness of the A36 steel plate, and the A36 steel plate of 20 mm or less does not contain Mn. The ASME SA572 carbon steel plate sheet, Q235 steel plate has requirements for the contents of C, Si, Mn, S, P and other elements. But SS400 steel plate only requires S and P to be less than 0.050, and no other element requirements.

On September 14th 2019, a Australia customer purchased 500 tonsDIN17155 15Mo3 boiler steel plates, which will be used for vessel modification of wax backflow protection project and LPU project. Many old customers keep asking about Din17155 steel grade-15Mo3. Usually our company would suggest customers to choose EN10028 steel specification, but if customer insiste on the old steel grade, we could arrange it either. With years of experience in produceing DIN 17155 15Mo3 boiler steel plates, the company supplies high quality steel ASME SA572 carbon steel plate sheet product with low cost and better service.

It is a modern high-tech professional enterprise integrating scientific research, ASME SA572 carbon steel plate sheet production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as ASME SA572 carbon steel plate sheet process technology development, technology transfer and related technical consulting and technical services.
