EN P690Q EN 10028-6
Boiler and Pressure Vessel Steel Product Introduction
EN P690Q EN 10028-6 steel grade is a type of high-strength steel grade used in structural and pressure vessel applications in Europe. It is made up primarily of elements like chromium, molybdenum, and nickel. EN P690Q EN 10028-6 steel offers a number of advantages over traditional mild steel grades, including high strength-to-weight ratios, excellent weldability, and good resistance to corrosion and high temperatures. This steel is commonly used in applications found in oil and gas, chemical, boiler, and pressure vessel industry applications.
Our company has steel products billets, steel products, hot-rolled sheets, cold-drawn sheets, seamless steel pipes, steel bars and other products. EN P690Q EN 10028-6 has a good reputation in the market, high-quality products, and thoughtful service in the steel industry. EN P690Q EN 10028-6 has complete specifications, and the products are widely used in aerospace, petrochemical, and construction projects, with low requirements for products, easy processing and low dimensional accuracy requirements. And provide cutting, bending, welding, drilling, and other processing services.
Application: Pressure flat steel products - Part 6: Weldable fine grain steel, quenched and tempered.
Heat treated: 1787°C - 1787°C.
