hardox 450 vs ar500 biggest 6 mills South Africa

Chromium element (Cr element) can improve the strength and hardness of Hardox 450 vs ar500, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.

Wear resistant steel is very wear-resistant: for example, excavator bucket, long-term excavation requires good wear resistance. Wear resistant steel has a very high hardness: for example, scraper conveyor, if the hardness is not up to standard, it is extremely easy to fracture, resulting in very serious consequences. Wear resistant steel has good corrosion resistance: many equipment need to transport chemical corrosion products, so corrosion-resistant mechanical equipment is needed. Hardox 450 vs ar500, Wear resistant steel has good fatigue resistance: such as bearing steel ball, which can do fast and repeated movement, and need to guarantee performance.

There is no weld on the outer surface of seamless steel pipe, which is the change from round steel progressive perforation to hollow round bar, with good compression resistance. According to different materials, the processed finished products Hardox 450 vs ar500 are applicable to a wide range of fields (for example: machine gearbox gears, gear wheel axles, cams, worms, piston pins, claw clutches, high-pressure pipes and various fasteners, high-grade carburized parts, such as gears, shafts, etc.) in the medium containing nitrogen hydrogen mixture for fluid transmission. It can improve the utilization of materials.

The Metals Industry Organization last week discussed two things on the Article 232 of the U.S. Trade Expansion Act of 1962 “25% and 10% tariffs on imported Hardox 450 vs ar500, steel and aluminum products, respectively”implemented in March 2018, and CBP - US Customs and Border Protection Administrative Office considered to delay the payment of import tariffs.
