Q245R is a kind of low alloy pressure vessel steel under the Chinese GB/T 713 standard, which is widely used in the manufacture of boilers and pressure vessels with its excellent comprehensive properties. Its main features include good welding performance, medium strength and strong corrosion and heat resistance. With a minimum yield strength of 245 MPa, the Q245R is suitable for medium and low temperature environments (usually below 350 ° C) and can withstand impact, fatigue loads and moisture corrosion. Due to its low carbon content, this steel has high toughness and plasticity, which is easy to process and form, and is a highly cost-effective industrial material.
The chemical composition of the Q245R is strictly controlled to ensure its stable performance. The main components include carbon (C≤0.20%), silicon (Si≤0.35%), manganese (Mn 0.50-1.00%), phosphorus (P≤0.025%), sulfur (S≤0.015%), and trace elements such as chromium (Cr) and nickel (Ni) content is very low. This low carbon, low sulfur and phosphorus design reduces the tendency to cold brittleness, improves the reliability of the steel in harsh environments, and ensures that cracks are not prone to occur during welding.
In terms of size, the Q245R can be made into a variety of forms such as steel plate, steel coil or section steel. The thickness of the steel plate is usually between 5 mm and 250 mm, the width range is 1500 mm to 3500 mm, and the length can be up to 3000 mm to 27000 mm, the specific specifications can be customized according to customer needs. Its flexible size makes it suitable for a variety of machining needs, such as cutting, bending and welding.
The Q245R is usually delivered hot rolled, but can also be controlled rolled, normalized or stress-relieved on request. The hot rolled condition is suitable for most conventional uses, while the normalizing treatment optimizes the internal structure of the steel to improve strength and toughness. The surface can be sandblasted or coated to enhance durability.
In terms of application, Q245R is widely used in petrochemical, natural gas, electric power and other industries, commonly used in the manufacture of reactors, heat exchangers, separators, spherical tanks and liquefied gas bottles and other equipment. In addition, it also has important applications in nuclear power pressure shell, steam turbine cylinder and coal chemical equipment. Its pressure and temperature resistance characteristics make it ideal for medium and low pressure boilers and vessels, especially in engineering projects requiring long-term stable operation. With its practicality and economy, Q245R has become one of the indispensable materials in the industrial sector.
