Popular hardox 400 machining material hardness

The yield strength of A36, D36, E36 and F36 is not less than 355N/mm^2, and the HARDOX 400 machining tensile strength is 490~620N/mm^2. A, D, E and F respectively indicate that they can be at 0° and -20 ° respectively. Impact toughness that can be achieved at -40℃, -60 ℃.

Cleveland cliffs, the largest HARDOX 400 machining iron ore company in North America, announced on April 13 that its Northshore mine in Minnesota and Tilden mine in Marquette County, Michigan, will suspend production based on the current market environment. The company said it would reduce inventory levels in both regions, while continuing to HARDOX 400 machining ship iron ore to its customers to meet commercial agreements.

The work performance of HARDOX 400 machining etc. steel material is mainly depended on its chemical composition, mechanical properties etc. parameters. The higher strength the steel has, the less quantity steel is needed to achieve same strong effect of the steel structure. However, the steel strength varies with the thickness. So please take steel thickness into consideration when evaluating the steel strength. For a certain steel, its strength also has something to do with the steel shape. For example, for a same steel grade, the steel strength is different for steel plates and pipes.

The coalition of American metal manufacturers and users, representing the interests of the downstream industries of American metals, strongly urged the Trump authorities to immediately repeal the regulation of imposing tariffs on imported HARDOX 400 machining, steel and aluminum products in Article 232 of the trade expansion act of 1962, aiming to relieve the pressure on the relevant American metal manufacturers in the epidemic.
