The Sanming stainless steel welded pipe machine, recommended the three subjects of stainless steel machinery 


 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! 
 The following is a promotional article, has nothing to do with this company 

 To organize preparations for the subsequent quenching. Temperature phase of carbide ball effect depends mainly on the surface carbon content, surface carbides will occur to the role of the local ball. If the appearance of the high carbon concentration, will form a coarse mesh or a large block carbides, then the ball effect the appearance of carbon concentration, so necessary to control electromechanical 0.85% workers 

 Hardness testing standards of the shaft furnace has three categories, the network reported. Three Vickers, Rockwell and the appearance of Rockwell hardness value. According to the same heat treatment, the appearance of quenching heat disposal furnace and disposal of chemical heat furnace hardness test method is not the same chemical treatment the main technical parameters of the workpiece is the depth of hardened layer 

 Thus changing the surface chemical composition, organization and surface hardness. Still have to use the Vickers hardness tester to detect the depth of hardened layer. Detected from the surface to the hardness down to the point where the distance 50HRC. This is the effective depth of hardening. The chemical treatment is to make the workpiece appearance infiltration of one or several chemical elements, atoms. 

 Workpiece appearance with high hardness, wear resistance and contact fatigue strength, performance. After quenching and tempering. The core of the workpiece with high strength and toughness. Similar appearance of the chemical heat treatment of the workpiece hardness test with the appearance of quenching hot hardness test of the disposal of the workpiece, Vickers hardness, appearance Rockwell hardness tester
