1.4404 stainless steel has good welding performance and is suitable for multi-layer welding. It has no tendency of knife edge corrosion after welding and has good corrosion resistance to sulfurous acid, sulfuric acid, phosphoric acid, acetic acid, formic acid, chloride, halogen and sulfite. This stainless steel has good cold and hot processing performance, good thermoplasticity of steel, low overheat sensitivity, and the suitable hot processing temperature is 900-1000℃.
1.4404 stainless steel equivalent standards: UNS S31603; EN 1.4404; JIS SUS316L; 00Cr17Ni14Mo2.
Is 1.4404 stainless steel magnetic?
It is an austenitic material, so it is a non-martensitic stainless steel. Its characteristics are non-magnetic.
1.4404 stainless steel corrosion resistance:
1.4404 stainless steel is also a derivative steel of 18-8 austenitic stainless steel, with 2-3% Mo added. The Mo content of 1.4404 makes this steel have excellent pitting resistance and can be safely used in environments containing halogen ions such as Cl-.
Since 1.4404 is mainly used for its chemical properties, steel mills have slightly lower surface inspection requirements for 1.4404, and customers with higher surface requirements should strengthen surface inspection efforts.
1.4404 stainless steel heat treatment specifications and metallographic structure:
Melting point: 1375~1450℃;
Heat treatment specifications: solid solution 1010~1150℃ rapid cooling;
Metallographic structure: the structure is characterized by austenite.
1.4404 stainless steel application:
1.4404 stainless steel is widely used in heat exchangers for pulp and papermaking equipment, dyeing equipment, film processing equipment, pipelines, food industry, coastal facilities, ropes, CD rods, bolts, nuts.
