hardox 500 abrasion resistant material spec
After tempering at 500-650 ℃, the NM400 wear-resistant plate has tempered sorbite structure, which has high comprehensive mechanical properties of strength and toughness. Quenching and tempering treatment is mainly used for all kinds of important structural parts, so that the strength, plasticity and toughness of wear-resistant plate, HARDOX 500 abrasion resistant can reach the appropriate match, and have good comprehensive mechanical properties.
Generally speaking, rolled plates are easier to handle in a high temperature environment, and the heat treatment of HARDOX 500 abrasion resistant, rolled plates is also very common. Hot rolling can not only greatly reduce energy consumption and save costs, but also improve the processing performance of metals and alloys, that is, the coarse grains in the as-cast state are broken, the cracks are healed significantly, and the processing performance of the alloy is improved.
Welded steel pipe refers to the steel pipe with a joint on the surface which is welded after the steel strip or steel plate is bent and deformed into circular, square and other expected shapes. According to different welding methods, it can be divided into arc welded pipe, high frequency or low frequency resistance welded pipe, gas welded pipe, furnace welded pipe, Bondi pipe, HARDOX 500 abrasion resistant, etc. According to the weld shape, it can be divided into straight welded pipe and spiral welded pipe. Electric welded steel pipes are mainly used in oil drilling and production, machinery manufacturing, etc.; furnace welded pipes can be used as water gas pipes, large-diameter straight seam welded pipes for high-pressure oil-gas transmission, etc.; spiral welded pipes are used for oil-gas transmission, pipe piles, piers, etc. Welded steel pipe has lower cost and higher production efficiency than seamless steel pipe.
Ultrasonic flaw detection emits ultrasonic waves to the HARDOX 500 abrasion resistant 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 HARDOX 500 abrasion resistant steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.
