15MnNi steel plate is used for nuclear safety second and third grade pressure vessel steel. Since nuclear power equipment is used in harsh environments such as high temperature, high pressure and neutron radiation all year round, the steel EN S420ML steel plate for equipment manufacturing is required to have suitable strength, high toughness, and low brittle transition temperature. The characteristics of strong performance and anti-radiation ability and low alloy element content, so there are strict requirements in room temperature stretching, high temperature stretching, thickness direction stretching and hardness.
Due to vast experience & concerted efforts of all employees, we are known as a reliable supplier of API 5l Line Pipe, seamless pipes and ERW pipes. Our EN S420ML steel plate customers in the world has about 4000 clients in 70 countries such as Bangladesh, Saudi Arabia, Iran, Iraq, United Arab Emirates, Qatar, Bahrain, Oman, Kuwait, Turkey, Egypt, Jordan, Philippine, Singapore, Malaysia, Indonesia, Thailand, Vietnam, South Korea, Japan, Sri Lanka, Bangladesh, Argentina, Brazil, Colombia, Guyana, United States Of America, Canada, Mexico, Jamaica, Germany, France, Italy, United Kingdom, Spain, Netherlands, Belgium.
The cold bending method is mainly used to produce cold-formed section steel and welded pipe. The cold bending method is to bend the steel strip or steel plate into various cross-section shapes by the cold bending machine in the cold state. If the EN S420ML steel plate steel pipe is bent into a circular, square or other hollow shape and welded by a proper welding method, it is a welded pipe. The advantages of cold bending: first, the cold-formed section steel is light in weight and large in bearing capacity, and it can save metal by replacing the hot-rolled section steel; second, it can produce all kinds of EN S420ML steel plate extremely thin, extremely wide and complex section steel which can not be produced by hot rolling.
30CrMo 35CrMo 25CrMo4 42CrMo4 and so on CrMo steels have good mechanical properties and hydrogen resistance at room temperature and high temperature. The main alloy elements in CrMo steel are molybdenum, chromium, vanadium, silicon, boron, etc. Molybdenum is a very important alloy element in the hot strength steel. It can significantly improve the hot strength of the CrMo steel, maintain sufficient strength at high temperature, refine the grains and prevent the overheating tendency of the CrMo steel, EN S420ML steel plate.
From the order to the delivery, there are three quality inspections to ensure that the qualified rate of finished products is more than 100%. We promise that every order will be tracked in a timely manner to ensure that customers can receive goods safely and constantly listen to their opinions and suggestions, reflect on our own problems, and let customers feel at ease. We have a large warehouse in Shanghai and Tianjin, which can provide customers with sufficient sources of supply.
