Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the A515 Grade 60 equivaelnt grades steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of A515 Grade 60 equivaelnt grades seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.
The impression of most customers who have cooperated with us on the company is being professional and responsible. That mainly owe to our united and considerate team members. For example, the professional technician, the responsible QC inspector, the experienced sales person, the rigorous document maker, the patient after-sales, etc. Their selfless devotion bring the customer good experience, and bring the company good reputation.
Compared with ordinary steel, structural steel has the following differences. First, the strength of structural steel is high, and its bearing capacity is far greater than that of ordinary steel. Second, the structural steel has low impurity and carbon content, uniform material and good performance. Third, structural steel has light weight and is suitable for building various frames. Fourth, it is convenient to build structural steel, which is conducive to construction efficiency and reduces construction time. In some construction fields, structural steel must be used. Where can we find A515 Grade 60 equivaelnt grades, structural steel suppliers?
Advantages of A515 Grade 60 equivaelnt grades: 1. Steel purity: Wugang can produce high purity molten steel with P 0.010%, S 0.005%, N70ppm, O15ppm, H2ppm, and 20ppm total inclusions in the steel. 2. Good toughness and weldability. 3. The heat treatment technology: normalizing, quenching, tempering, tempering and other heat treatment processing can be carried out on the steel plate as required. 4. Significantly improve the plasticity and impact toughness of steel, and improve the anisotropy of steel.
