Product Knowledge of 202 Stainless Steel Pipes

Q1: What is the difference between 202 stainless steel pipes and 201 stainless steel pipes?

A1: The main differences lie in nickel content and corrosion resistance. 202 has a nickel content of 3%-5%, and 201 has a nickel content of 1%-3%; 202 has better corrosion resistance than 201, not easy to rust, and the price is 10%-20% higher than 201, suitable for mid-end decoration and basic industrial scenarios.

Q2: What are the common specifications of 202 stainless steel pipes?

A2: The common outer diameter for foreign trade is 6mm-168mm, and the wall thickness is 1mm-5mm. Among them, the demand for pipes with outer diameter of 15mm-57mm and wall thickness of 1.2mm-2.5mm is the largest, which are suitable for scenarios such as decoration, basic pipeline transportation and simple equipment connection.

Q3: Can 202 stainless steel pipes be used in outdoor decoration scenarios?

A3: They can be used for short-term outdoor decoration (such as temporary guardrails, activity signs), but not suitable for long-term outdoor open-air scenarios, especially coastal, rainy and humid areas. Rust spots are easy to appear after long-term use. It is recommended to do anti-rust treatment when used outdoors.

Q4: What is the foreign trade export advantage of 202 stainless steel pipes?

A4: The advantage is high cost performance. The price is between 201 and 304, and the corrosion resistance is better than 201, which can meet mid-end needs. It is suitable for foreign trade customers sensitive to cost but hoping to improve corrosion resistance, and the export volume is second only to 201 and 304 pipes.

Q5: What is the welding performance of 202 stainless steel pipes?

A5: The welding performance is good. It can be welded by argon arc welding, electric arc welding and other methods. No special treatment is required after welding, and it can maintain good mechanical properties. However, the corrosion resistance of the welding joint will decrease slightly. It is recommended to do anti-rust coating treatment after welding.
