430 Stainless Steel
Introduction
Overview of 430 Stainless Steel
430 stainless steel is a general purpose stainless steel with good corrosion resistance.
It has better thermal conductivity than austenite grade stainless steel, a smaller thermal expansion coefficient than austenite stainless steel, heat fatigue resistance.
Due to addition of stabilizing element titanium, it has good mechanical properties of welding.
Because of its chromium content, it is also called 18/0 or 18-0. Compared with 304 stainless steel, it contains slightly less chromium, and the hardness is correspondingly lower.
Features of 430 Stainless Steel
- Good corrosion resistance
- Good formability
- Good ductility
430 Stainless Steel Applications
- Chemical industry: chemical storage tank, vessel, heat exchanger;
- Food industry: liquid storage tank, evaporator;
- Agricultural industry: steam boiler and condenser;
- Papermaking industry: boiler tube;
- Metallurgy industry: heat-exchanger tube in metallurgical industries.
