Martensite strengthened steel wire is oil quenched spring steel wire. Carbon steel or alloy steel can be used as needed. After surface treatment and cold drawing to the size of the finished product, induction heating or gas or oil heating furnace can be used to heat the steel wire to the austenitizing temperature for a period of time. After quenching, a medium temperature tempering treatment can be performed to obtain it. Steel wire can achieve good comprehensive mechanical properties through quenching and tempering treatment
Due to the high yield ratio of oil quenched and tempered steel wires, 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 save the need for winding the spring
Some processes, and the high yield of spring winding, can reduce costs.
Our company's patented product: oil quenched tempered special shaped spring steel wire, fully combines the advantages of special shaped steel wire and oil quenched steel wire, further improving the labor productivity of downstream products.
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 round steel wire has excellent properties such as high hardness, high strength, good toughness, and wear resistance. Its hardness can reach HRC45-60, and its strength can reach over 1800MPa.
In addition, oil quenched round steel wire also has excellent properties such as tensile strength, yield strength, and impact toughness.
Usage: Oil quenched round steel wire is widely used in the manufacturing of various mechanical equipment, tools, and components, such as automobiles, motorcycles, aerospace, ships, machine tools, molds, cutting tools, etc
Domain. Its main uses include the following aspects:
1. Mold manufacturing: Oil quenched round steel wire can be used to manufacture molds, such as plastic molds, die-casting molds, stamping molds, hot pressing molds, etc., to meet the requirements of high strength and high wear resistance.
2. Tool manufacturing: Oil quenched round steel wire can be used to manufacture various tools, such as cutting tools, milling cutters, drill bits, turning tools, etc., to meet the requirements of high hardness and high wear resistance.
3. Mechanical components: Oil quenched round steel wire can be used to manufacture various mechanical components, such as bearings, springs, bolts, nuts, pins, etc., to meet the requirements of high strength and wear resistance.
4. Other: Oil quenched round steel wire can also be used to manufacture various special purpose components, such as spring steel wire, spring plate, steel wire rope, etc.
