weathering steel Q295NH material equivalent standards

13CrMo4-5 steel plate delivery status and production process is strictly produced according to EN10028-2 standard. Delivery status: normalizing + tempering, tempering. The 13CrMo4-5 alloy plates thickness below 100mm, it is normalizing + tempering; Thickness 100mm-150mm, the plate is delivered in normalizing + tempering or quenched and tempered;150mm-250mm is delivered in tempered condition. The requirements for flaw detection levels, and Z-direction functional requirements can also be added.The company adheres to green development, supported by scientific and technological innovation and technological progress, vigorously advocates the weathering steel Q295NH production and life style of saving, environmental protection, civilization and low carbon, adheres to the new industrialization road and the sustainable development road. Actively carry out international trade and maintain stable economic and trade relations with more than 80 countries and regions including the United States, Germany, France, the United Kingdom, Japan, South Korea and Australia.The deoxidization process of Q345R boiler vessel plate if the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the weathering steel Q295NH steel, when sufficient amount of strong oxidant is added to make the steel deoxidize well, the co bubble will escape during the solidification process and generate boiling phenomenon, no co bubble will be generated during the solidification of the weathering steel Q295NH steel, the steel used for the pressure vessel of the killed steel is called the killed steel, this kind of steel is called the boiling steel.After adding a small amount of niobium, vanadium and titanium to weathering steel Q295NH etc. steel, it is combined with the controlled rolling process to control the precipitation behavior of microalloying elements to achieve the purpose of improving the comprehensive properties of the steel, whether it is strength, toughness, ductile-brittle transition temperature, or Steel's process formability, welding performance, corrosion resistance and crack resistance have been significantly improved, while reducing production costs. Such steel products are widely used in oil and gas pipelines, vehicles, building structures, oil production platforms, pressure vessels, ship shells and many other fields.First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
