Precipitation hardening steel is steel formed on the basis of the chemical composition of stainless steel by adding different types and amounts of strengthening elements. After special heat treatment processes, such as precipitation hardening process, different types of carbides, nitrides, carbonitrides and intermetallic compounds are precipitated in the steel. This can improve the strength of the steel and maintain sufficient toughness.
Occasion Applicable
1. High temperature, high strength conditions: precipitation hardening steel, especially austenitic precipitation hardening stainless steel, suitable for high temperature, high strength working environment. This type of steel has good strength and heat resistance, and can withstand extreme temperatures and pressures.
2. Normal temperature and normal pressure conditions: ferritic stainless steel is more suitable for normal temperature and normal pressure working environment. It has excellent strength, toughness and corrosion resistance, suitable for general working environment.
Applications of Precipitation Hardening Steel
1. Aviation and aerospace fields: PH14-8Mo and 15-5PH stainless steel are widely used in aviation and aerospace fields. They are used to make high-strength, high-corrosion resistant components such as aircraft engines, gas turbines, and turbine blades. These materials are able to withstand extreme temperatures and pressures while having good corrosion resistance.
2. Nuclear industry: Because of its good corrosion resistance and high strength, it has also been widely used in the nuclear industry. Such as the manufacture of nuclear reactor pressure vessels, pipes, valves and other key components.
3. Marine development field: Ferritic stainless steel is also widely used in the field of Marine development. Because it has excellent corrosion resistance and can withstand the corrosion of seawater, it can manufacture various equipment in Marine engineering, such as ships and ocean platforms.
4. Petroleum and chemical fields: PH14-8Mo and other precipitation hardening stainless steel are also widely used in petroleum and chemical fields. They can manufacture a variety of corrosion-resistant pipes, valves, pumps and other equipment to ensure that these devices can operate properly in harsh chemical environments.
5. Other fields: In addition, it is also used in medical equipment, power equipment and other fields. For example, 15-5PH stainless steel because of its good corrosion resistance and high strength, high toughness, can be used to manufacture hydraulic rods, shafts, gears, screws, valves, pump housing, cycloidal reducer, drill pipe and other high-strength parts.
