Different 310S stainless steel round bars and rebars Stainless steel round bars and rebars are common names for different types of steel bars. What is the difference between the two? Mainly reflected in five aspects! Matrix Light,Matrix Beam Led,Led Matrix Effect Light,Matrix Blinder Led EV LIGHT Guangzhou Co., Ltd , https://www.evlightpro.com
1. "Phase" is different: the surface of stainless steel round steel is smooth and the surface of the rebar is spiral.
2. Different production standards: In the production standard, stainless steel round steel refers to HPB235 grade steel bar, "hot rolled smooth steel bar for reinforced concrete" is its production standard, and rebar refers to HRB335 and HPB400 steel bar, "rebar Hot rolled ribbed steel for concrete.
3. Different strength: The design strength of stainless steel round steel is 210MPa. The design strength of rebar HRB335 is 300MPa, and the design strength of HRB400 is 360MPa.
4. The difference of steel grade: stainless steel round steel belongs to carbon steel, steel grade is Q235, and rebar is lower alloy steel.
5. Different physical and mechanical properties: Because the chemical composition and strength of the two steel bars are different, the physical properties are also different. The cold bending performance of stainless steel round steel is better, and it can be used as a 180 degree hook and thread. Steel can only be used as a 90 degree straight hook; stainless steel round bar has good weldability, and ordinary carbon electrodes can be used, but rebar must use low alloy electrode. Rebar is generally constructed with reinforced concrete facilities. The material is generally 16mn or 45 carbon steel. The yield strength is above 350MPa, and the tensile strength is above 500MPa. It is higher than ordinary low carbon steel or stainless steel round steel. A lot, so it is not difficult to see that the rebar is better than the stainless steel round in terms of toughness and fatigue resistance.
Because the surface of the threaded steel has a thread shape, it can increase the firm adhesion with the concrete. The threaded steel is the preferred material for the longitudinal reinforcement of the concrete member and the stirrup.
