The workpiece is reheated to 100-150 ℃ and kept for 5-20 hours. This kind of treatment for stabilizing the quality of precision parts is called aging. Aging treatment of steel components under low temperature or dynamic load conditions is particularly important to remove residual stress and stabilize the structure and size of hot-pressed elbows. Quenching and tempering treatment: The heat treatment method of high temperature tempering after quenching is called quenching and tempering treatment. High temperature tempering refers to tempering between 500 and 650°C.

Carbon steel elbow quenching and tempering can make the performance of steel, material has a great degree of adjustment, its strength, plasticity and toughness are better, has a good comprehensive mechanical properties. Annealing of carbon steel hot-pressed elbow: The hot-pressed elbow is heated to temperature and kept for a period of time, and then it is slowly cooled, which is called annealing. The annealing of hot-pressed elbow is a heat treatment method that heats the steel to the temperature of phase change or partial phase change, and slowly cools after insulation.

Stainless steel flange production process is different: At present, the production process of stainless steel flange is divided into steel plate gas cutting flange, steel plate splicing flange, steel plate rolling flange, forging forming flange, flange and cylinder splicing forming long and high diameter flange. Among them, the raw material cost and cost of forging the flange are high.

The management mode of stainless steel flange manufacturers is different, resulting in different costs: the company's management mode is different, and everyone will think that the process of blanking, production and turning will not be much different. Have you ever thought that the flange needs to be tested after production, so as to meet the delivery status of the flange as the customer's demand, but the labor cost, equipment cost and rejection rate of the testing are directly omitted by some manufacturers.
