Introduction of 25CrMnSiA steel plate and its application in industry
Introduction to 25CrMnSiA Steel Plate 25CrMnSiA is a low-alloy high-strength structural steel, which belongs to
medium-carbon quenched and tempered steel, which can obtain high comprehensive properties after quenching and tempering treatment, and is often used in some high-strength important components

is mainly used to manufacture tie rods, important welding and stamping parts, high-strength structural parts, etc
25CrMnSiA steel plate cutting: Steel plate cutting refers to the process of using natural gas flame (oxygen-natural gas) to preheat the cut metal to a point where it can burn violently, and then release a high-pressure oxygen flow to further oxidize the metal violently and blow off the slag produced by combustion to form a cut. Steel plate cutting methods include flame cutting, laser cutting, wire cutting, shearing machine, plasma cutting, ultra-high pressure water cutting and other methods, the cost of flame cutting equipment is low and is a cost-effective means of cutting thick metal plates, but it has its shortcomings in thin plate cutting. So thick plates are generally cut with flames.
