The Ultrasonic flaw detection principle of p265gh steel tube

Pageviews:

In recent years, in line with the development trend of iron and P265GH steel tube steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which p265gh steel tube are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

S690QL high-strength steel is used for low temperature, high strength key components, construction machinery, mining machinery structure, etc. European standard high strength steel plate, p265gh steel tube, manufacturing various types of construction machinery, such as mining and various types of construction drilling rig, electric shovel, electric wheel dump truck, mining truck, excavator, loader, bulldozer, various types of cranes, coal mine hydraulic supports and other structural parts.

Corrosion resistant steel is a kind of stainless steel, which can resist corrosion in some strong corrosive media. Stainless steel can only resist corrosion in air or weak medium. Stainless steel is not necessarily corrosion resistant, corrosion-resistant steel must be stainless steel. Corrosion resistant steel is durable and can be stored outdoors for a long time without being damaged in bad weather. Corrosion resistant steel is not easy to rust, but it is not absolutely rust free. The strength, precision and toughness of p265gh steel tube, corrosion resistant steel are very good, and can be the processed and used for many purposes.

Cold rolled p265gh steel tube steel sheet can be produced by two high mill, four high reversing mill, multi high reversing mill and tandem cold mill. Although there are still only two work rolls in four high and multi high rolling mills, each work roll is supported by one or more large diameter backup rolls, which can prevent deflection of work roll. As a result, wide and thinner p265gh steel tube steel plates can be produced. For example, 20 high mill can produce as thin as 0. 001 mm sheet, but the two high mill can only produce as thin as 0. 35mm sheet

As to the Chemical composition, the different content is a main on carbon content, while the carbon content of p265gh steel tube, A283Gr. D is no more than 0.27% and it is higher than Grade C (≤0.24%) ; as to the mechanical property, the differences are tensile strength and yield strength, while the tensile strength of ASTM A283 Gr.D is 415-550MPa (60-80 ksi) and yield strength of ASTM A283 Grade D is 230MPa (33 ksi).
