Jiaxing Industrial pipe machine, stainless steel mechanical specialized factory - three subjects! 

 The Chenzhou three subjects Stainless Steel Co., Ltd. was established in 1993, is dedicated to high-end stainless steel tube complete sets of equipment, high-tech enterprises, the company has a number of independent research and development, patents, and passed the ISO9001 quality management system certification and the company have independent import and export rights. Three subjects because of its superior performance, ultra-high quality, cost-effective, other major vendors in the industry, far ahead, a number of large group companies and strength of state-owned enterprises are the property of our company long-term customers, the product has a high good quality "subjects" well-known overseas, the products are exported to: Malaysia, Taiwan, Vietnam, Bangladesh, Kenya, Russia and other countries with foreign high-end products competing against. With the continuous development of the company in 2009, "Chenzhou Section Stainless Steel Co., Ltd. phase Foshan superior geographical location and mature market environment set up in Foshan Nanhai Luo village of Foshan branch of the" three companies influence further to expand. 
 Three subjects stainless steel decorative tube machine and stainless steel industrial tube series products according to the different needs of the customer groups targeted segments, and then combined with the actual situation of the customers from the two series is subdivided "high-end machines, precision machine, the three grades of" ordinary machines "to meet the different needs of customers. Section "Device specifications vary, from ￠ 6 ￠ 325 tube thickness from 0.2mm ~ 8mm. Molds, polishing machine, embossing machine, leveling machine, annealing equipment and other equipment readily available, providing customers with the perfect service of the whole head to tail, the customer does not have to worry about. 
 Company has always adhered to "focus on quality, creating value for customers" business philosophy! Warmly welcome the sincere cooperation of all walks of life, and common development! 

 Address: Foshan City, Guangdong Province, Luo village Works Village Rong Xing Industrial Zone, D3 Block 
 The following is a promotional article, has nothing to do with this company 



 Casting high temperature graphitization annealing castings cooling. Often occur White. White tissue hard and brittle, poor processing performance, easy to peel. Therefore necessary to adopt the annealing (or normalizing) method to eliminate white tissue. Annealing process as follows: heated to 550 950 ℃ insulation 25h, followed by furnace cooling to the process of graphitization. By the cross sections. 

 500 550 ℃ and then cooled baked. High temperature insulation, high travel cementite and eutectic cementite decomposition of secondary cementite eutectoid cementite decomposition in the cooling process for graphite and A subsequent care. Cause the decrease in hardness, in the decomposition of cementite. To improve machinability. The purpose of three ductile iron and grain refinement, fireball iron normalizing 

 In order to improve the mechanical properties of the castings. Sometimes normalizing surface hardening ductile iron organizational preparation, normalizing the sub-high-temperature normalizing and low temperature. High-temperature normalizing temperature is generally not more than 950 980 ° C, in order to obtain pearlite matrix. Uniform organization. Low temperature is to eliminate the normalizing internal stress. 4 hardened ductile iron 

 The fire is generally heated to a total of folding temperature range of 820.86 thousand ℃. After normalizing the general need for treatment. General casting is heated to 3050 ℃ above Afc1 (Afc1 on behalf of the heating A martensite formation of the end of the temperature) Paul. In order to properly reduce the residual stress after quenching and tempering in order to improve the mechanical properties of ductile iron. Temperature
