Heat-resistant castings, Public Li Xin (certified), Hangzhou, wear-resistant castings from Linyi Public Li Xin Machinery Limited. Linyi Public Li Xin Machinery Co., Ltd. (www.lyzlx.com) is specialized in the "steel castings, cast steel, heat-resistant steel, ordinary steel castings," the enterprise, the company of "honesty, hard service" concept, for you provide the highest quality products and services. Welcome to inquire! Contact: Peng. Linyi Public Li Xin Machinery Co., Ltd. is the design, production, processing, marketing as one of modern science and technology enterprises wear-resistant castings, using the current international advanced casting (EPC) a negative real casting wear-resistant castings manufacturers, production Multi-temperature casting materials, corrosion castings, abrasion resistant castings, steel castings and other antioxidant. The products are widely used in metallurgy, mining, chemicals, shipbuilding, paper, machinery, military and other industries. Production process and quality in a leading position, with metal spectrometer, and other advanced detection equipment. Martensitic steel and pearlitic heat-resistant steels, austenitic steels are heat-resistant steel of the major categories. ? So strengthening mechanism martensitic steel is a kind of how it, strengthen the organization: that is heat-resistant steel and solid solution strengthening satiety. 2, precipitation hardening: heat-resistant steel by changing the type and amount of precipitates to enhance the strength of the heat-resistant steel, which is a heat-resistant steel reinforcing most common method. 3, dislocation strengthening: the use of dislocation way to enhance the heat just resistance to deformation. 4, the grain boundary strengthening: mainly by increasing the substructure refinement and grain to increase the strength of heat-resistant steel. 5, dispersion strengthening: by adding the number of carbide particles and to reduce the spacing to enhance the thermal performance of heat-resistant steel strength. Linyi Public Li Xin Machinery Co., Ltd. is the design, production, processing, marketing as one of modern science and technology enterprise, the use of advanced international casting today (EPC) of a negative real casting process to produce more material casting temperature resistance corrosion castings, abrasion resistant castings, steel castings and other antioxidant. The products are widely used in metallurgy, mining, chemicals, shipbuilding, paper, machinery, military and other industries. Production process and quality in a leading position, with metal spectrometer, and other advanced detection equipment. 1, stainless steel castings After cooling to an elastic state, is subjected to mechanical stress due to shrinkage resulting from obstruction, called heat-resistant castings mechanical obstruction stress, mechanical stress hinder the performance of tensile stress or shear stress. 2, due to mechanical obstruction stress is generated when the elastic state wear-resistant castings manufacturers, reasons for the formation of stress upon elimination (eg casting off the sand and after the removal of the gate), the stress will disappear, so that stress is a mechanical obstruction temporary stress. Mechanical obstruction casting thickest part stress and residual thermal stress directions are the same, the two stress superposition, the thickest part of the casting will sometimes happen Ling crack. Mechanical obstruction casting thin section stress and residual thermal stress in the opposite direction, the stress can offset some of each other, but when casting the thin part of the mechanical obstruction stress is too large, exceeding the ultimate strength of the alloy, also occurs in the thin part of the cold cracking. For more information you wish to bring convenience, but you are welcome to visit our company to purchase, we sincerely look forward to cooperating with you. Focus on now, looking to the future, I will strive to meet the needs of users now, and strive to develop future user needs and struggle!
