Based on the advantages of a537 class 1 properties steel resources in domestic market and good reputation, combining with the huge international market demand for steel products, our company started the international business in 2010 and successfully being approved and certified by ISO9001:2008, the Registration number is 626014Q11531R0S. With the quality steel a537 class 1 properties products and professional service, our company was award the international acclaim from infrastructure, shipbuilding, petroleum industry etc., and gradually grow into a bright star in the steel export industry .
SPV355 steel is a kind of Japanese standard steel for medium temperature pressure vessels. The executive technical standard of SPV355 steel is JIS G3115. SPV355 steel is widely used in petroleum, chemical industry, power station, boiler and other industries. SPV355 steel is used to make reactor, a537 class 1 properties heat exchanger, separator, spherical tank, oil and gas tank, liquefied gas tank, nuclear reactor pressure shell, boiler drum, liquefied petroleum cylinder, high-pressure water pipe of hydropower station, turbine volute and other equipment and components.
35# steel is a high-quality medium carbon carbon structural steel, with good plasticity and appropriate strength, good process performance, and acceptable welding performance. It a537 class 1 properties is often delivered in normalized and tempered state. 35 # steel is widely used in the manufacture of various forged and hot-pressed parts, cold-drawn and a537 class 1 properties upset forged steel, seamless steel tubes, and parts in machinery manufacturing.
Corrosion resistance mechanism of a537 class 1 properties, stainless steel: obvious Cr2O3 film is formed on the surface of stainless steel, and the minimum content of O and Cr (10.5%) is required to obtain continuous protective film to prevent corrosion. If the protective film is damaged, it can recover naturally.
S355NL steel plate is under EN10111 standard. We can regard a537 class 1 properties, S355NL steel plate as Fine-grain structural steels, normalised rolled. S355NL steel plate is one mainly of Fine-grain structural steels, normalised rolled, The normalized rolled fine-grain structural steel S355NL is characterized by a minimum yield strength of 355 MPa, by good weldability and high resistance to brittle fracture, which is same with DIN:TStE355 and BS:55EE
