15Mo3 steel is a kind of pearlitic heat-resistant steel, which can still show its characteristics under high temperature and long time load. 15Mo3 steel is used for heating surface of low and medium pressure boiler (working pressure is generally not more than 588MPA, and working temperature is below 450 ℃) 15Mo3 steel is widely used in petroleum, chemical industry, power station, boiler and other industries 15Mo3 steel is used to make reactor, heat exchanger, separator, spherical tank, oil and gas tank, liquefied gas tank, etc,A514 Gr A alloy steel plate.
40Cr steel plate is one of the most widely used steel in machinery manufacturing. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel A514 Gr A alloy steel plate is good It can be hardened to Ф28 ～ 60mm during water quenching and Ф15～40mm during oil quenching When the hardness is HB174～229, the relative cutting workability is 60% The steel is suitable for making medium-sized plastic molds,A514 Gr A alloy steel plate.
Ultrasonic flaw detection emits ultrasonic waves to the steel plate under inspection. If there are defects in the steel plate, the ultrasonic waves will reflect, refract or deform waveforms due to the defects. By recording these changes, the type and shape of the defects are analyzed. Due to its high energy and good penetration performance, and the smoothness of the steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.
A514 Gr A alloy steel plate,S355J2 steel plate yield strength Rp0.2≥265mpa, tensile strength RM: 450-680mpa, elongation a≥12%, impact energy Kv2≥27J, tensile area shrinkage Z≥35% in thickness direction. S355J2 steel plate has good internal quality, high density and stable performance.Meaning of S355J2-Z35: J2 requires negative 20 degree impact, and Z35 is the Z-direction performance of S355J2 steel plate.The meaning of S355J2 + N-Z35: J2 requires negative 20 degree impact, N means normalizing rolling rather than normalizing. Z35 is the Z-direction performance of S355J2 steel plate.A514 Gr A alloy steel plate
