introduction：In die forging，The forging blank is forged into a product with a certain geometry in a first or multiple forging die。For slender forgings（That is, the length size of the forged workpiece is significantly larger than its cross-section size）Pre-redistribution of blank mass is usually included in forging、There are several forging steps such as cross section forming and final forming。In the traditional form forging，The excess material usually becomes the raw edge of the forging，These rough edges need to be removed before final forging。 In recent years，The hot forging forming process of steel has been greatly developed and changed。In addition to new forging dies and forging equipment，forging

introduction： The physical properties of stainless steel are mainly expressed in the following aspects： ①Coefficient of thermal expansion A change in the measuring element of a substance caused by a change in temperature。The coefficient of expansion is expansion－The slope of the temperature curve，The instantaneous expansion coefficient is the slope at a specific temperature，The average slope between two specified temperatures is the average coefficient of thermal expansion。The coefficient of expansion can be expressed as volume or length，It is usually expressed in terms of length。 ②density The density of a substance is the mass per unit volume of that substance，The unit is...kg/m3or1b/in3。
