Difference between Q235 steel and Q345 steel: First, The lower limit of yield strength of Q235 steel is 235MPa, and that of Q345 steel is 345MPa. Second, Q235 steel is common carbon steel, Q345 steel is low alloy steel. They have different alloy contents. Besides, Q235 steel is for general strength application, Q345 steel is for higher strength application. A588 Grade A tensile strength ksi, Q345 steel price is higher than Q235 steel price. But Q345 steel can save materials for sake of high strength.
Myanmar 4800 tons ABS AH36 and ABS A shipbuilding plates. This is very good customer of us, and we have cooperated many times for shipbuilding plates A588 Grade A tensile strength ksi . The most frequently ordered is shipbuilding plates, almost hundreds tons every 2 month, which are finally supplied to Myanmar’s navy. Just in last year, we have supplier more than 4800 tons shipbuilding plates for the customer continuously.
The difference between Q195 steel and 20# steel: A588 Grade A tensile strength ksi, Q195 steel is ordinary carbon structural steel, in which alloy elements are not specially added, and it is mainly used for construction and engineering structures. Q195 steel has low carbon and manganese content, low strength, good plasticity, high toughness, and good process performance and weldability. 20# steel is high-quality carbon structural steel. Alloy elements are not specially added to 20# steel, and it is mainly used in the manufacture of machine structures, and the amount of use is particularly large. 20# steel has higher strength than Q195 steel, good weldability, no temper brittleness, and its workability can be improved by water quenching.
Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled A588 Grade A tensile strength ksi plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive A588 Grade A tensile strength ksi industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.
