Chemical composition: Q355 steel is composed of carbon, silicon, manganese, phosphorus, sulfur, and some other elements. The exact chemical composition can vary depending on the specific manufacturer and production process.
Tensile strength: Q355 rebar has a minimum tensile strength of 355 MPa (51,500 psi) according to the Chinese standard GB/T 1499.2-2018. This makes it stronger than Q235 rebar, which has a minimum tensile strength of 375 MPa.
Yield strength: The yield strength of Q355 rebar is typically around 345 MPa (50,000psi).
This is the point at which the steel begins to deform permanently under stress, and is an important factor in determining the strength and durability of the rebar.
Size: Q355 rebar is available in a range of sizes, from #3 to #40. The nominal diameter of the rebar ranges from 9.5 mm to 40 mm.
Surface treatment: Q355 rebar can be treated with various surface coatings or treatments to improve its resistance to corrosion and other environmental factors. These treatments can include hot-dip galvanizing, epoxy coatings, or other specialized coatings.
Standards: Q355 rebar is manufactured according to various international and national standards, including the Chinese standard GB/T 1499.2-2018.
Applications: Q355 rebar is commonly used in construction projects where high strength and durability are required. It is suitable for use in reinforced concrete structures, such as buildings, bridges, and tunnels.
