Product of description

Duplex 2507 is a duplex stainless steel material with high strength and excellent corrosion resistance. The following are the material characteristics and application description of Duplex 2507 round steel:

Material features:

Two-phase structure: Duplex 2507 has the characteristics of two-phase (austenite phase and ferrite phase) structure, which makes it have excellent strength and corrosion resistance. This structure allows Duplex 2507 to perform well in aggressive media such as strong acids, strong bases and chlorides.

High strength: Duplex 2507 has high strength, especially yield strength and tensile strength. This allows it to perform well in high-load and high-stress environments and have a long service life.

Good corrosion resistance: Duplex 2507 has good corrosion resistance and can resist the erosion of a variety of corrosive media, including acidic and alkaline environments, chloride environments and high temperature environments. It has excellent resistance to stress corrosion cracking.

Good welding performance: Duplex 2507 has good welding performance and is suitable for various commonly used welding methods, such as arc welding and argon arc welding. The welded joint has good strength and corrosion resistance.

application:

Oil and gas industry: Duplex 2507 round steel is widely used in oil and gas exploration, storage and processing. It can be used to make pipelines, valves, oil well equipment and offshore platforms, etc. It has excellent corrosion resistance and stress corrosion cracking resistance.

Chemical industry: Duplex 2507 round bar is suitable for the treatment of corrosive media in the chemical industry. It can be used to make chemical equipment, storage tanks, reactors, etc., and can resist strong acid, strong alkali and salt solution and other corrosive environments.

Ocean engineering: Because Duplex 2507 round steel has the ability to resist salt spray and seawater corrosion, it is often used in the field of ocean engineering, such as making offshore platforms, offshore drilling equipment, seawater treatment equipment, etc.

Food processing industry: Duplex 2507 round steel has good corrosion resistance and mechanical properties, so it is widely used in the food processing industry. It can be used to make food handling equipment, storage containers, delivery systems, and more. The corrosion resistance of Duplex 2507 round bar ensures food safety and sanitation.

The process of making Duplex 2507 round bar generally includes the following steps:

Raw material preparation: choose Duplex 2507 stainless steel material that meets the standard requirements as the raw material for making round steel. The raw material can be Duplex 2507 stainless steel plate, coil or rod.

Cutting: Cut the Duplex 2507 stainless steel material into required length workpieces using cutting equipment such as shears, saws, etc.

Heat treatment: Heat treatment of the cut workpiece, usually including solution treatment and quenching treatment. These heat treatments increase the hardness and strength of the material and adjust its crystal structure.

Rough machining: Rough machining of the workpiece after heat treatment, including turning, milling, drilling and other processes, to form a preliminary circular shape and rough size.

Hot rolling or cold drawing: hot rolling or cold drawing of the roughly machined workpiece to make it gradually reach the required diameter and shape. Hot rolling and cold drawing are commonly used processes to improve the compactness, dimensional accuracy and surface quality of the material.

Finishing: Finishing the hot-rolled or cold-drawn workpiece, including fine grinding, bright treatment and other processes, to further improve its surface quality and dimensional accuracy.

Cleaning and impurity removal: Clean and remove impurities on the finished Duplex 2507 round steel to remove dirt, grease and impurities on the surface to ensure the purity and hygienic performance of the final product.

Inspection and quality control: Carry out quality inspection on the produced Duplex 2507 round steel, including inspection on size, chemical composition, physical properties, etc., to ensure that the product meets the requirements of the standard.

Packaging and storage: Properly package the finished Duplex 2507 round steel to prevent surface damage and corrosion, then store or transport to the destination.
