Stainless steel vacuum flask: It is made of double layer of stainless steel, inner and outer shells. The welding technology is used to combine the inner shell and the outer shell, and then vacuum technology /furnace to pump the air between the inner and outer shell of the flask to vacuum insulati...
According to different media, carbonitriding is divided into solid, liquid and gas three kind. Solid carbonitriding is similar to solid Carburizing, and 30% 40% yellow blood salt 10% ammonium carbonate and 50% 60% charcoal are often used as infiltrating agents. This method has low production effi...
Carbonitriding refers to a chemical heat treatment process in which carbon and nitrogen atoms penetrate into the surface of the workpiece at the same time. Carbonitriding was first carried out in a salt bath containing cyanide, so it is also called cyanation. The combination of carburizing and ni...
Tool steels are usually supplied in the annealed condition, around 200/250 Brinell (about 20 HRC), to facilitate machining. In this condition, most of the alloy content exists as alloy carbides, dispersed throughout a soft matrix. These steels must be heat treated to develop their characteristic...
The pattern is surrounded, or “invested”, into ceramic slurry that hardens into the mold. Investment casting is often referred to as “lost-wax casting” because the wax pattern is melted out of the mold after it has been formed. Lox-wax processes are one-to-one (one pattern creates one par...
Vacuum furnaces generally have more leakage faults in the spring and autumn, and leakage failures occur easily when they are idle for a long time.
