Applications of 1.4841 Forged Stainless Steel Bar:

• Industrial Furnaces: Furnace tubes, rollers, supports, and structural parts exposed to high temperatures.

• Heat Treatment Equipment: Fixtures, trays, and components requiring stability at elevated temperatures.

• Petrochemical Industry: Heat-resistant vessels, reformer parts, and cracking furnace components.

• Power Generation: Boiler parts, superheater tubes, and high-temperature fasteners.

• Chemical Processing Plants: Components exposed to oxidizing environments at high temperatures.

• Automotive & Aerospace: High-temperature bolts, flanges, and fittings.

• General Engineering: Shafts, bars, and custom forged parts requiring creep resistance and oxidation resistance.

Welding:
Grade 1.4841 can be welded using standard techniques without the need for preheating. Due to its susceptibility to hot cracking, the heat input should be kept as low as possible. Post-weld heat treatment is not required. For filler material, grade 1.4842 is recommended. It should be noted that excessive heat input during welding may negatively affect the corrosion resistance.

Forging:
Forging operations can be performed within the temperature range of 1175 °C to 1000 °C, followed by rapid cooling in water or air to achieve the desired properties.

Machining:
Machining of 1.4841 requires reduced cutting speeds and shallow cutting depths to ensure good tool life and surface finish.

Corrosion Resistance:
This grade offers only limited resistance to oxidizing and reducing sulfur-containing gases. Therefore, its use under such conditions should be restricted to service temperatures below 650 °C.
