Why there are quality defects on the surfaces of Corten B yield

The company adheres to the people-oriented concept and takes "learning, sharing, gratitude, integrity, respect and responsibility" as the enterprise values. Advanced equipment, scientific standardized management, strict quality assurance system and high-quality team are the core competitiveness of the company. The company will continue to provide customers with Corten B yield high-quality, timely and perfect steel products and services under the guidance of the mission of "striving for perfection to meet customer needs".

SAE4340, same as UNS G43400. Tensile strength σb ≥980(100) Yield strength σs ≥835(85), used to manufacture important parts with high strength and good plasticity. After nitriding treatment, make important parts with special functional requirements, such as shafts, gears, and gears. Firmware etc. Delivery Corten B yield in heat treatment (normalizing, annealing or high temperature tempering) or without heat treatment.

Weathering steel plate Corten B yield for welding structure is made by adding chromium, molybdenum, titanium, vanadium and other metal materials into common steel liquid. Adding these materials can form a protective film on the surface, which can resist the corrosion of climate for a long time. Advantages: this kind of steel plate Corten B yield has excellent welding performance and weather resistance, and is widely used in railway, bridge and other areas requiring long-term exposure to the atmosphere.

Boiler steel is different from Corten B yield. Boiler steel is used to make boilers. Boiler steel can be divided into steel for boiler steel pipe, boiler steel plate and boiler steel fasteners. Boiler steel is smelted by open hearth furnace, converter, electric furnace, and some also use the refining process outside the furnace. Boiler steel for steel pipes refers to the steel used for the manufacture of superheaters, reheaters and headers. Their working temperature is higher than other parts, and the environment is also harsher.

S355J2 steel plate belongs to European standard low alloy steel, the executive standard is EN10025-2. Delivery status: normalizing, hot rolling or control rolling. S355J2 corresponds to the Chinese Q345D, but the executive standard is different, the chemical composition is slightly different, but their mechanical properties are the same. S355J2 low alloy steel plate tensile strength (MPA): 450-680, impact value: - 20 ℃: ≥ 27J. Corten B yield, S355J2 low alloy steel plate is widely used in bridges, vehicles, ships, buildings, steel structures, etc.

The steel plate, steel pipe and other steel materials are the important material in the material engineers. Our company will provide the high quality the steel plate, steel pipe and other steel materials for you. We are exported the steel plate, steel pipe and other Corten B yield steel materials to the customers from USA, South America, Europe, Africa etc. If we can have the good cooperation together, you will be very welcome to be our agent in your local market.
