Stainless Steel Grade 409 is ferritic steel with good mechanical features and resistance to corrosion at high temperatures, making it an excellent choice for high-temperature applications. It is usually referred to as chromium stainless steel because of its use in automobile exhaust systems and other applications that need weldability.
The inclusion of niobium, titanium or a combination of the two elements in the composition of steels ensures the stability of SS 409 grade. To fulfil more stringent shaping requirements than usual Type 409 steel, Bhavya Steel, one of the top exporters and suppliers of stainless steel sheets and plates in Mumbai, develops alloys that are particularly ideal for applications involving more complex designs and better weldability.
Applications of Stainless steel 409:
A specific application for Type 409 SS sheets and plates, coils is the protection it provides against oxidation and corrosion, which is beyond carbon steel capabilities and some coated steels.
Current applications include exhaust systems for automobiles, tubular dispensers, agricultural spreaders, and silencers of gas turbines, heat exchangers and the filters of fuels.
This alloy exhibits excellent resistance to oxidation and corrosion in automobile and non-automotive exhaust applications.
Grade 409 performs well in moist environments and is less vulnerable to corrosive cracking than other grades. It was formerly applied in automobile exhaust pipes but is now used in muffler tubing and catalytic converter casings.
Stainless Steel Grade 409 Plates has remarkable strength and hardness and also outstanding corrosion resistance. Annealing of Stainless Steel 409 Pipes is performed between 790 and 900 degrees Celsius, followed by air cooling. Thermal treatment does not affect the hardness of grade 409 steel. Most advanced exhaust systems are constructed with 409 stainless steel. It is robust and will last for eight to ten years in a moderate environment.
SS 409 has a wide range of uses in the oil field, chemical industrial equipment, aviation fittings, fasteners, pumping shafts, nuclear plant components, gearboxes, paper mill machinery, missile fixtures, and jet engine components, and also the petrochemical sector. In addition to these applications, the SS 409 is notable for its strength and thermal treatment properties.
Type 409 Stainless Steel can be found in various industries and applications due to its excellent features.
- Aerospace – manifolds for piston engines
- Chemical Refinement
- Joints of Expansion
- Equipment and storage for the food processing industry
- Service for polythionic acid in the petroleum refining industry
- Thermal oxidizers for waste treatment
Benefits of Grade 409:
- When compared to 304 Stainless Steel, this alloy has higher creeping stress and rupture qualities.
- Ideal for use in high-temperature environments
- Overcomes sensitivity and corrosion issues
- It can be utilized for high-temperature ASME Boilers and Pressure Vessel Code applications
- Outstanding mechanical properties
