What is the carbon content of NM400 cold bending
The company adheres to the carbon content of NM400 business tenet of "integrity casting strength, cooperation creating win-win", takes value-added service of supply chain as the tenet, and under the premise of existing market, bulk trade, logistics distribution and other advantages, develops a new comprehensive steel industry model combined with informatization. And will continue to provide customers with high-quality steel products and good service. We sincerely welcome new and old customers to join hands with our company carbon content of NM400 and seek common development!
The alloy steel plates carbon content of NM400 are among our main steel products. There are various alloy steel grades on the market. The most popular alloy steel materials are European material under EN10083-3 and Chinese material under GBT3077 for round bars and GBT11251 for plates. Our typical alloy steel grades are 51CrV4, 25CrMo4, 34CrMo4, 42CrMo4, 12Cr1MoV, 20Cr, 40Cr, 15CrMo, 30CrMo, 35CrMo, 42CrMo, etc.
Pipeline steel can be divided into three types: high cold, high sulfur area and submarine laying. According to the development trend, service conditions, main failure forms and failure reasons of oil and gas pipelines, it is required that the pipeline steel carbon content of NM400 not only has good mechanical properties, but also has negative temperature resistance, corrosion resistance, seawater resistance and hsscc resistance. These pipelines with bad working environment have long lines and are not easy to maintain, so they have strict quality requirements.
With the increase of temperature, the yield limit of carbon content of NM400 will decrease monotonically, but the tensile strength of carbon content of NM400 will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of carbon content of NM400. Near the blue brittleness temperature, the carbon content of NM400 strength increases and the plasticity decreases. The elongation and section shrinkage of carbon content of NM400 increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.
A588 Grade A steel plate is for high strength low alloy structural steel with 345Mpa minimum yield point to 100mm thickness."When propertly exposed to the atmosphere, A588 Grade A is suitable for many applications in the bare condition. carbon content of NM400, A588 Grade Acould be produced in 200mm in our company.
We are leading supplier of pipeline steel. The pipeline steel in usually in forms of pipeline steel coils, pipeline steel sheet, pipeline steel plate and pipeline steel pipes. And the most popular standard is API 5L. For questions about carbon content of NM400 pipeline steel, such as X70 steel properties, API 5L X42 steel properties, difference between API 5L PSL1 and API 5L PSL2, API 5L grade B steel price, please feel free to communicate with us.
