SS Square Tube Description
Stainless steel square pipe is a type of stainless steel tubing with a square or rectangular cross-section. The unique geometric shape provides extra strength in structural applications.SS Square tubes are divided into seamless and welded types. Seamless stainless steel square pipe is formed by extruding seamless round tubes.
Type 304/304L is the basic “18-8” chromium-nickel stainless steel,the most commonly used stainless steel alloy,with strong formability and excellent weldability,known for its strength and corrosion resistance.
304 Stainless Steel Features
- Fair Machinability
- Good Corrosion Resistance
- Excellent Weldability
- Good Bending/Forming Properties
- No Magnetic
Stainless steel pipes are in different grades, categories and in shapes.Stainless steel pipes are being manufactured in different shapes,sizes, schedules and diameters as every application requires different size and diameter. HNJBL stainless pipes are available in different grades,as grade 201,304,304L,316,316L,etc.Stainless steel tubing is easy to weld, cut, bend, and be processed into various shapes and sizes according to specific needs to adapt to different application scenarios.
