hardox 500 sheets supplier equivalent in indian standard

The company now has HARDOX 500 sheets supplier oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments. The staff with college degree or above accounted for more than 80%, and there were more than HARDOX 500 sheets supplier 30 professional and technical personnel. The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m.

Vanadium mainly exists in the form of carbide in HARDOX 500 sheets supplier and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.

"The latest data from the General Administration of Customs shows that from January to February 2020, China exported 500,000 tons of coal and lignite, a year-on-year decrease of 60.2%. From January to February, China exported 360,000 tons of coke and semi-coke, a year-on-year decrease of 474.2%. From January to February, China imported 68.06 million tons of coal and lignite, a year-on-year increase of 33.1%."

The wear-resistant plate HARDOX 500 sheets supplier shows good wear resistance: the chemical composition of the alloy layer contains 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%, the macro hardness is HRC56-62, and the hardness of chromium carbide is HV1400-1800. Because of the vertical distribution of carbides in the wear direction, the wear resistance of the cast alloy with the same composition and HARDOX 500 sheets supplier hardness is more than twice as that of the cast alloy with the same composition and hardness. Compared with several typical materials, the wear resistance is as follows: (1) compared with low carbon steel; 20-25:1 (2) with as cast high chromium cast iron; 1.5-2.5:1.
