- Stainless steel pipes are long, hollow tubes that are used for a variety of purposes. We prodce stainless steel pipes by two distinct methods which result in either a stainless steel welded or seamless pipe.
- When compared to mild steel pipes, stainless steel pipes have:
- Higher corrosion resistance
- Higher cryogenic toughness
- Higher work hardening rate
- Higher hot strength
- Higher ductility
- Higher strength and hardness
- A more attractive appearance
- Lower maintenance
- Corrosion Resistance
- All stainless steels are iron-based alloys that contain a minimum of around 10.5% Chromium. The Chromium in the alloy forms a self-healing protective clear oxide layer. This oxide layer gives stainless steels their corrosion resistance. The self healing nature of the oxide layer means the corrosion resistance remains intact regardless of fabrication methods. Even if the material surface is cut or damaged, it will self heal and corrosion resistance will be maintained.
- Conversely, normal carbon steels may be protected from corrosion by painting or other coatings like galvanizing. Any modification of the surface exposes the underlying steel and corrosion can occur.
- The corrosion of different grades of stainless steel will differ with various environments. Suitable grades will depend upon the service environment. Even trace amounts of some elements can markedly alter the corrosion resistance. Chlorides in particular can have an adverse effect on the corrosion resistance of stainless steel.
- Ferritic, martensitic and precipitation hardening steels should not be used at sub-zero temperatures. The toughness of these grades drops significantly at low temperatures. In some cases this drop occurs close to room temperature.
