Properties of SA588 Grade B steel

SA588Grade B steel, SA588GrB for short, is an American standard weather-resistant steel plate that complies with ASTM/A588M standards. It forms a dense protective film on the steel surface through a specific alloying design to improve its atmospheric corrosion resistance.

SA588Grade B Features:

High weather resistance: SA588Grade B steel can effectively resist the expansion of corrosion through the protective film formed on the steel surface by alloying, which significantly improves the atmospheric corrosion resistance of steel. It remains stable for a long time even in harsh outdoor environments, such as industrial atmospheres or Marine climates.

Good mechanical properties: The steel has a high yield strength and tensile strength, while maintaining good elongation and toughness. This enables it to maintain stable structural performance despite large loads and shocks.

Easy processing: SA588Grade B steel can be made into structural parts of various shapes and sizes by cutting, bending, drilling and other processing methods, with good processing performance.

Environmental protection and energy saving: Due to its high weather resistance, it reduces the maintenance and replacement frequency of steel, thus saving resources and energy, in line with the concept of environmental protection and energy saving.

Chemical composition of SA588Grade B steel:

Carbon (C) : ≤0.20%

Silicon (Si) : 0.15-0.50%

Manganese (Mn) : 0.75-1.25%

Phosphorus (P) : ≤0.03%

Sulfur (S) : ≤0.03%

Nickel (Ni) : ≤0.50%

Chromium (Cr) : 0.40-0.70%

Copper (Cu) : 0.20-0.40%

Vanadium (V) : 0.01-0.10%

SA588Grade B steel has a very wide range of applications, mainly including the following aspects:

Construction field: Used to manufacture a variety of weather-resistant building structural parts (especially for industrial atmospheric environment) and bridge auxiliary structural parts.

Bridge engineering: Because of its high weather resistance and good weldability, SA588Grade B steel is widely used in bridge construction for welding Bridges and buildings, reducing weight or increasing durability.

Construction machinery: Used to manufacture all kinds of construction machinery and equipment and its structural parts, such as mining and all kinds of engineering construction RIGS, shovels, electric wheel dump trucks, mining cars, excavators, loaders, bulldozers, all kinds of cranes, coal mine hydraulic support, etc.

Other fields: It is also widely used in automobiles, metal products, household appliances, precision electronics, containers, machinery manufacturing, elevators, sanitary ware, rail transit and other fields.
