2304 Duplex Stainless Steel

2304 Duplex Stainless Steel

2304 (UNS S32304, EN 1.4362) stainless steel is a low-alloy duplex stainless steel composed of 40%-50% ferrite and 50%-60% austenite. This general steel grade is often used to replace the austenitic stainless steels 304L and 316L. Gnee is a professional stainless steel supplier and manufacturer in China, supplying high-quality 2304 stainless steel, consult for a quote and get a free sample!

The yield strength of 2304 duplex stainless steel is much higher than that of austenitic stainless steel. It has high strength and toughness and is resistant to stress corrosion. It has the advantages of crack resistance, high thermal conductivity, low thermal expansion, and easy manufacturing. This steel is not recommended for use in areas subject to prolonged exposure to temperatures in excess of 1058°C (570°F).

What Services Does Gnee Provide?

Gnee can provide the following measurement services for stainless steel:

Dimensional Measurement: Measure dimensional parameters such as length, width and thickness by measuring instruments to ensure that the stainless steel is qualified and meets the design requirements.
Surface Measurement: Measure parameters such as flatness, bumpiness and surface roughness of the stainless steel surface to help ensure that the quality and surface condition of the stainless steel meets the requirements.
Thickness Measurement: Use thickness gauges to accurately measure the thickness of the stainless steel to ensure it meets the design requirements.
Material Measurement: Use material analysis instruments to measure the chemical composition and mechanical properties of the stainless steel to ensure that the quality and properties of the stainless steel meet the requirements.
Bending And Deformation Measurements: Use tools such as bending gauges and displacement sensors to measure and monitor the degree of bending and deformation of stainless steel to ensure that it is within the allowable range.

Ask Measurement service

Gnee can customize the size and shape of your stainless steel for your specific project needs. Custom design of stainless steel is carried out by a team of professional engineers and designers. Based on the project requirements and constraints, they will use calculation and simulation tools combined with experience and technical knowledge to optimize the stainless steel design to meet the specific needs of your different projects

● Adjustment of the thickness, width and length of stainless steel based on load calculations and strength requirements for structural design.
● The shape of the stainless steel can be designed according to the demand characteristics.
● If the convenience of installation and maintenance is considered, we can also add openings and passages for easy access and operation in the design for areas that require frequent maintenance.

Ask Customized Services

Sourcing Gnee stainless steel can provide the following further processing services. We can customize to meet the specific needs of our customers for different projects.

Cutting Service: Stainless steel can be custom cut to obtain the desired shape and size according to the customer’s needs. For example, flame cutting, plasma cutting, laser cutting, etc., can cut stainless steel into desired plates, blocks, shaped pieces, etc.
Bending & Forming: Stainless steel is bent and formed by applying stress and appropriate processes to obtain the desired shape.
Welding Services: Stainless steel can be subjected to various types of welding services, including manual arc welding, gas-shielded welding, laser welding, etc.
Hole Turning And Machining: Stainless steel is turned and holes are machined through the use of machining equipment. These processes produce smooth surfaces, precise holes and threads to meet specific assembly requirements.
