Martensite strengthened steel wire is oil quenched spring steel wire. Carbon steel or alloy steel can be used as needed, and after surface treatment and cold drawing to the finished size, induction heating or gas can be used
A fuel oil heating furnace is used to heat the steel wire to the austenitizing temperature and hold it for a period of time. After quenching, it is then subjected to a medium temperature tempering treatment to obtain. The steel wire can be quenched and tempered
Obtaining good comprehensive mechanical properties.
Due to the high yield to strength ratio of oil quenched and tempered steel wire, the residual deformation of the spring is small, which is beneficial for winding the spring and improving the fatigue life of the spring. Compared with traditional spring production methods, it can be omitted
Some processes after spring winding, and the high yield of spring winding can reduce costs.
Our company's patented product: oil quenched tempered shaped spring steel wire, which fully combines the advantages of shaped steel wire and oil quenched steel wire, further improving the labor productivity of downstream products
Yield. In recent years, there has been a trend for medium and large-sized oil quenched tempered steel wires to replace cold drawn steel wires.
Performance: Oil quenched irregular steel wire has excellent properties such as high hardness, high strength, and high wear resistance. Its hardness can reach HRC45-60, and its strength can reach over 1800MPa.
In addition, oil quenched irregular steel wires also have excellent properties such as tensile strength, yield strength, and impact toughness.
Usage: Oil quenched irregular steel wire is widely used in the manufacturing of various mechanical equipment, tools, and components, such as automobiles, motorcycles, aerospace, ships, machine tools, molds, and cutting tools
And other fields.
Its main uses include the following aspects:
1. Manufacturing high-strength components: Oil quenched irregular steel wire can be used to manufacture various high-strength components, such as bearings, gears, machine tool spindles, molds, etc., to meet the requirements of high strength and high wear resistance.
2. Manufacturing high wear resistant components: Oil quenched irregular steel wire has good wear resistance and can be used to manufacture various high wear resistant components, such as abrasive tools, stamping molds, extrusion molds, etc.
3. Manufacturing springs and elastic components: Oil quenched irregular steel wire can be used to manufacture various springs and elastic components, such as automotive suspension springs, valve springs, fixture springs, etc.
4. Manufacturing cutting tools: Oil quenched irregular steel wire can be used to manufacture various cutting tools, such as drills, reamers, gear shapers, etc.
