Quenched and Tempered Piston Rod Quenched and Tempered Cylinder Rod Solid Solution Stainless Steel Rod

Quenched and Tempered Piston Rod Quenched and Tempered Cylinder Rod Solid Solution Stainless Steel Rod

The quenched and tempered piston rods are characterized by high strength and good ductility. Thermal refining is a heat treatment method combined of quenching and high-temperature tempering.

Product Details

1.Brief Introduction to the Quenched and Tempered Piston Rod

The quenched and tempered piston rods are characterized by high strength and good ductility.

Thermal refining: Generally, the heat treatment method combined of quenching and high-temperature tempering is called thermal refining, which is widely applied to various important structural parts, especially the connecting rods, bolts, gears and shafts working under alternating load. The tempered sorbite has better mechanical property than normalized sorbite of the same hardness. Its hardness depends on tempering temperature and relates to stability of tempering and sectional dimension of workpiece, and is generally HB200-350.

2.Product Specifications of Quenched and Tempered Cylinder Rod

In a general sense, quenching is a form of heat treatment performed on various types of steel. Although there is a special heat treatment cycle for each steel type, the thermal refining heat treatment process generally involves heating carbon steel for mechanical structures with a greater than 0.3% carbon content together with alloy steel until they reach the austenite region of around 850 degrees Celsius. Then, they are rapidly cooled by water or oil which transforms them into a martensite structure.

Tempering is a heat treatment used to give toughness to steel that has been hardened through quenching. From a martensite structure, the steel is reheated to between 550 and 650 degrees Celsius. Cooling is then performed after the structure retains this temperature for a certain predetermined period of time.

Quenching and tempering heat treatment is used to adjust the mechanical properties of the steel, with the entire series of processes referred to as thermal refining heat treatment.

(Although the hardness of steel will increase by quenching alone, tempering is generally performed to achieve a greater resilience since toughness will decline as a result of quenching.)

3.Our Advantages in Manufacturing Quenched and Tempered Steel Rod

a. High Quality Raw Material: We mainly select large steel plant raw materials, such as TPCO, BAO STEEL and SHA STEEL, these are the best Chinese largest producers of raw materials.

b. Short Delivery Time: If a container is 15-20 days. We have some standard sizes of tubes and sticks in stock. If you need 3-5pcs, we can deliver it very quickly.

c. Safe Packing: The anti-rust oil is carried out on the pipe and rod before transportation, and the plastic cap is protected on the inner surface at the end of the pipe. Each rod is protected by the cardboard tube. Finally, it is

packed in seaborne or wooden cases.

5.Package
After rigorous inspection, the last important thing is safe packing. Anti-rust oil is to be sprayed on rod surface and each rod is to be packed in paper sleeve and then in wooden box.
