The torque calculation of the forged steel ball valve is as follows: the square of the valve diameter of the one-half of the valve is 3.14, which is the area of the valve plate, and then the static pressure accepted by the shaft is obtained by the pressure of the stainless steel ball (ie the worki... read more
The quality of stainless steel ball products has an inextricable relationship with the steel ball production process. The quality of the steel ball needs to be controlled, and it is necessary to understand the problems that the process technology needs to pay attention to. First of all, the stainles... read more

First, the material influence, steel, cast iron, alloy steel, etc., the density of different materials is different, the density of steel is larger than that of cast iron, and the alloy steel varies according to the density and content of the main alloying elements. Second, the influence of the stee... read more
Stainless steel ball heat treatment first understand why heat treatment, from the metallographic structure, stainless steel beads are divided into austenitic stainless steel balls, martensitic stainless steel balls, and ferritic stainless steel balls, heat treatment of balls of different materials T... read more
