Standard type Mnl3 high manganese steel

Shandong Hill Mining Machinery Co., Ltd. standard of Mnl3 high manganese steel, high manganese and carbon content; cast structure of austenite and carbide steel, 1050 ℃ for water toughening treatment, the vast majority of carbide solid solution in austenite. Organization of single-phase austenitic steel and austenitic plus a small amount of carbide, with good ductility, toughness and non-magnetic characteristics. Since austenitic face-centered cubic lattice structure. Crack growth rate is very low, safe and reliable. Another feature of the steel is in the role of the larger impact load and contact stress, the surface layer will quickly produce hardening layer, the surface hardness of sharply increased (up to 500 ~ 700HBw); surface with good abrasion resistance, still inside maintaining good toughness. Not broken by the impact load. Can be mechanical and explosive method allows surface hardening before use. Type of steel used for impact abrasive wear and high stress crushed abrasive wear conditions, we used the place for Raymond grinding ring, roller; ball mill liner, hammer crusher hammer; excavator bucket teeth; tractor track shoe . High manganese national standards and relevant international standards. (1) high-manganese steel must be greater than or equal 1040 ℃ water toughening treatment. (2) The chemical composition is always checked. (3) Mechanical properties of high manganese steel. (4) gold high manganese steel of consistent national standards. We use EPC technology for modeling, for forming a casting must ensure that its dimensions, because it is not easy to welding, hardening. To leave margin when modeling appropriate, give full consideration to its shrinkage, solidification shrinkage 6. For the runner bar shape should take full account of its feeding situation, high manganese steel castings ingredients are content to GMn13-1 as C1. oO ~ i. 45, Mnii. 00 to 14. OO, Si0.30 ~ I. 00, S≤0.04, P≤0.09. In the selection of raw materials we need to focus on several key points. To charge when using cast manganese can be added to the burning. Other ingredients may be roughly unchanged. And we often encounter the problem of re-proportioning, carbon steel, manganese steel, structural steel and other steel categories. From the selection to the scrap classification, in principle, allow undesirable raw materials into steel on steel in question to be testing samples of the alloy to be added must test to ensure that the various elements of its content is not exceeded. And to ensure the content standards.
