Flat Stainless Steel Plate Sheet UNS S32304 S31803 S32750 S32550 S32706

UNS S32304 stainless steel is a duplex stainless steel that combines the characteristics of austenite and ferrite. UNS S32304 stainless steel plate has excellent corrosion resistance, high strength and good weldability. During the manufacturing process, it is crucial to understand its processing technology and processing hardness to ensure the quality and performance of the final product.

Carbon (C): ≤0.03, Silicon (Si): ≤1.0, Phosphorus (P): ≤0.03, Sulfur (S): ≤0.02, Chromium (Cr): 22-23, Nickel (Ni): 4.5-6.5, Nitrogen (N): 0.14-0.2

Its physical properties include its density, thermal expansion coefficient, thermal conductivity and elastic modulus. Its density is 8.2g/cm³, thermal expansion coefficient is 0.0000016cm/cm/°C, thermal conductivity is 16.2W/m·°C, and elastic modulus is 199GPa. These physical properties make UNS S32304 stainless steel plate show good stability and mechanical properties in both high and low temperature environments.

It has good corrosion resistance and can resist the erosion of strong corrosive media such as seawater, chlorides, sulfates, etc. It has better corrosion resistance than conventional austenitic stainless steel in chlorine-containing environments, and is not easy to produce red rust and pitting, and has better corrosion resistance and ductility.

It has high strength and hardness, about twice the strength of austenitic stainless steel, and has good fatigue resistance; its yield strength is twice that of 304L/316L austenitic stainless steel, which allows designers to reduce the weight of products when designing products; compared with 304 and 316 austenitic stainless steel, UNS S32304 stainless steel plate has stronger resistance to stress corrosion.

Welding performance: It has good welding performance and can be welded by conventional welding methods (such as TIG, MIG, etc.). After welding, the corrosion resistance and mechanical properties of the material can be restored by appropriate heat treatment.

It has good processing performance and can be formed by hot rolling, cold rolling and forging, which is suitable for different production needs.

Low magnetic properties: low magnetic permeability, can effectively reduce electromagnetic interference, provide better electromagnetic shielding performance, and is often used to manufacture magnetic isolators, medical device housings and other products with high electromagnetic shielding requirements

Five points to note in the manufacturing process of S32205 duplex stainless steel

During the manufacturing process of S32205 duplex stainless steel, the following points need to be noted:

1. Melting and casting: UNS S32304 stainless steel plate has a high melting point and solidification point. High temperature and reasonable cooling rate are required during melting and casting to ensure that the organization and performance of the material meet the requirements.
2. Heat treatment: The heat treatment of the material needs to be carried out under strict temperature and time control to avoid problems such as overburning, grain growth, and uneven organization.
3. Processing and forming: Since UNS S32304 stainless steel plate has good toughness and ductility, it is necessary to avoid cracks, wrinkles and other problems during processing and forming.
4. Welding: The welding of this material requires the use of reasonable welding processes and welding materials to ensure that the organization and performance of the welded joint meet the requirements. During the welding process, attention should be paid to the control of preheating, interlayer temperature and post-heating to avoid problems such as cold cracks.
5. Corrosion resistance treatment: During use, UNS S32304 stainless steel plates need to be cleaned and maintained regularly to avoid corrosion and dirt. In addition, surface treatment methods such as spraying and electroplating can be used to improve the corrosion resistance of the material.
