The heat treatment hardness of DC53 mold steel is higher than that of SKD11, A573 Gr 70 steel sheet, the high temperature is 520-530 ℃, and the high hardness can reach 62-63HRC after tempering. In terms of strength and wear resistance, mold steel DC53 exceeds SKD11 mold steel. The toughness is twice that of SKD11 die steel. The toughness of DC53 is more prominent in cold work die steel. Tools made with DC53 rarely crack and crack, greatly increasing the service life.
09CuPCrNi-A weather-resistant steel plate is one of weather-resistant steel (that is, atmospheric corrosion-resistant steel), used in sulfur-containing flue gas, air preheater, economizer, boiler air preheater, to prevent the vicinity of acid dew point, etc. Commonly used is low temperature weathering steel, which has a strong ability to resist low temperature corrosion. This type of steel A573 Gr 70 steel sheet has a protective effect against corrosion.
Ultrasonic flaw detection emits ultrasonic waves to the A573 Gr 70 steel sheet 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 A573 Gr 70 steel sheet steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.
As leading EN10025-6 S460QL structural steel plates supplier in China, our company has supplied hundreds of thousands tons S460QL steel plates to clients to assist them finish one after another A573 Gr 70 steel sheet magnificent projects.
