sa573gr.70 steel sheet for engineering

Q345B material is a low-carbon alloy steel (c <0.20%), with good overall performance, low temperature performance, cold stamping performance, welding performance and machinability. Q345R steel is a special plate for pressure vessels with a yield strength of 345MPa. It has good comprehensive mechanical properties and technological performance. In addition to the tensile strength and elongation requirements higher than Q345 (16Mn) steel, Q345R is also required to ensure impact toughness.

The microscopic strength of the sa573gr.70 steel sheet, wear-resistant steel plate refers to the strength of the hard phase, but the higher the strength, the higher the wear resistance. Strength is the basis of high-quality wear resistance of wear-resistant steel plates, but the relationship between strength and wear resistance is not proportional; wear-resistant steel plates are often wear-resistant, the root cause is that there are hard particles and soft conventions.

Cold rolled sa573gr.70 steel sheet 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 sa573gr.70 steel sheet 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

Both parties shall confirm the sa573gr.70 steel sheet material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the sa573gr.70 steel sheet steel plant.
