GB/T6479 16Mn/Q345B Seamless steel tubes for high

Q345 steel is a Chinese GB standard low alloy high strength structural steel, material density is 7.85 g/cm3, tensile strength is 470-630 Mpa, and yield strength is 345 MPa. Q is the first letter of Chinese Pinyin:qu fu dian, which means Yield Point, 345 is the minimum value of yield strength 345 MPa for steel thickness 16mm. Hot Rolling Carbon Steel Sheet Q235B Q345b Hot Rolled 1. Structural steelMainly used in the production of steel structure parts, bridges, ships and vehicles.2. Weather-resistant steelAdding special elements (P, Cu, C, etc.), has good corrosion resistance and atmospheric corrosion resistance, used in the production of containers and special vehicles, an Hot rolled 1500X6000mm size p355qh1 material properties 304 stainless steel plate products have strong corrosion resistance. For ordinary alkali solution and organic acid, inorganic acid has good corrosion resistance. This material p355qh1 material properties is a high alloy steel, which can resist corrosion in air or chemical corrosive medium.

Q235 Q345B Cuplock Scaffolding System Gang Board For

Construction Q235 Q345B Cuplock Scaffolding System Gang Board . Zhiyou Marine& Offshore CO., LTD. (Shanghai) is a rich experience company in shipbuilding&repairing and steel-structure making, specialized in designing, manufacturing, sales, installation, and maintenance service. Zhiyou has always been committed to exploring the most updated, scientific, and comprehensive material handling Q345B Steel Plate(Provide cutting square and bar) - LION The tensile strength of Q345B steel is rated at 470 to 630 MegaPascals (where mega is million) and a yield strength (where the material starts to thin and pull like taffy) at 345 MegaPascals. Like most steels of its grade, it suffers elongation before it pulls apart, typically at 20-21 percent of its initial length. Q355 Steel Properties, Composition & EquivalentQ355 steel has good mechanical properties, good weldability, hot and cold processing properties and corrosion resistance. Can be used to manufacture ships, boilers, pressure vessels, petroleum storage tanks, bridges, power station equipment, lifting transport machinery and other higher load welded structural parts. Q355 Steel Equivalent Grade

The performance and composition characteristics of steel

1. Performance characteristics of steel grade Q345B:(1)The strength of steel grade Q345B is higher than that of the carbon structural steel, which can reduce the weight of the structure and save steel. (2) Steel grade Q345B has sufficient plasticity, toughness and good weldability. (3) Steel grade Q345B has good corrosion resistance and low cold brittle transition temperature. 2. What is material Q345B equivalent ASTM steel - BEBON STEELMaterial Q345B equivalent ASTM steel A572 Gr 50 mechanical properties:The major benefit of material Q345B is its mild temper. Material Q345B is easy to form and easy to weld. Material Q345B is the combination of comparatively low price and ease of use, and that makes material Q345B a widely used material in construction. elongation of hardox 450 steel pdf - Wear/Abrasion The 345 at the back refers to the yield value of Q345B material, which is about 345MPa. The yield value will decrease with the increase of Q345B steel plate thickness. Q345B steel plate has good comprehensive performance, low temperature performance, cold stamping performance, welding performance and machinability.
