st37 S690QL placa de acero cold formability

The steel plate and strip after hot rolling treatment are generally called hot rolled plate. Compared with other steel plate processing industries, st37 S690QL placa de acero, hot rolled plate has these characteristics. First, low hardness, easy processing. Compared with other steel needs special mechanical equipment, hot rolled plate is a very convenient for processing. Second, good ductility, not easy to break, good compression capacity, long service life. Third, the manufacturing process is simple, and the price and cost are relatively cheap compared with other steels.

Chemical composition of st37 S690QL placa de acero, A514 Gr P steel plate (melting analysis %)
C: 0.14-0.18 Mn: 1.20 V: 0.03-0.08 Si: 0.10-.040 P: 0.025 S: 0.020 Cr: 1.0-1.5 Mo: 0.4-0.6
Mechanical properties of A514 Gr P steel plate:
Yield strength≥690MPa, tensile strength≥760-896MPa, elongation %≥16, Akv2 J / longitudinal ≥34, impact temperature - 40℃.

Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the st37 S690QL placa de acero steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This st37 S690QL placa de acero method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.
