Alternative Name: Half Coupling 1/4'' BSPT 316L Class 3000, heavy-wall stainless steel half coupling, high-pressure half coupling, inox half coupling, acid-resistant threaded coupling, full-port half coupling.
Information
Half Coupling 1/4'' BSPT 316L Class 3000 is manufactured from 316 / 316L stainless steel, providing excellent corrosion resistance together with outstanding welding and forming properties. Its heavy-wall construction is designed for high-pressure systems up to 206 bar.
316 / 316L Stainless Steel
316 / 316L stainless steel is one of the most widely used corrosion-resistant stainless steels. Thanks to the addition of molybdenum, it offers significantly better corrosion resistance than standard 304 stainless steel, especially in aggressive industrial environments.
Equivalent grades: DIN 1.4401, 1.4404, SS316, SS316L, AISI 316, AISI 316L.
Applications
- Heat exchangers
- Pharmaceutical equipment
- Dairy processing equipment
- Brewing industry
- Marine fittings
- Coastal structures
- Food processing industry
Advantages of 316 / 316L Stainless Steel
- Non-magnetic
- Excellent ductility
- Excellent impact toughness
- Outstanding weldability
- Good mechanical strength
- Wide operating temperature range
