Product Overview
Stainless steel thin-walled steel pipe is a type of pipe material made from stainless steel, processed through precise rolling, drawing, welding and other techniques. The ratio of pipe wall thickness to pipe diameter is relatively small (usually the wall thickness is ≤ 3mm, and the diameter-thickness ratio is ≥ 20). It is a high-precision pipe.
Material and Chemical Composition:
The main material of the thin-walled stainless steel tube is austenitic stainless steel. The specific models are mainly 304 stainless steel, 304L stainless steel, 316 stainless steel, and 316L stainless steel.The core components are slightly different. The main components are as follows, taking 304 and 316 materials as examples:
| Materials |
Cr |
Ni | C | Si | Mn |
| 304 | 18.00%-20.00% | 8.00%-11.00% | ≤0.08% | ≤1.00% | ≤2.00% |
| 316 | 16.00%-18.00% | 10.00%-14.00% | ≤0.08% | ≤1.00% | ≤2.00% |
Available Size/ Range
Outer Diameter: 6mm-219mm
Wall Thickness: 0.5mm-6mm
Length: 3m,6m,Custom
Mechanical Properties
The mechanical properties of stainless steel thin-walled pipes depend on the material and processing techniques. The following are the core mechanical performance indicators (at room temperature) for the main types of materials:
