STAINLESS STEEL CONSERVATION
1. Clean frequently with a cleaner and water. Any cleaner that is safe for glass is usually safe for stainless steel.
2. Scrub off all rust from these objects with a scrubbing pad or steel wood pad. This means getting rid of rust from pots and pans before putting them into a stainless steel sink or on top of a stainless steel stove. 3. Put a rubber mat at the bottom of the stainless steel sink before placing rusted pots and pans (such as cast iron cookware) in the sink. 4. Apply a thin layer of lubricant (such as mineral oil) to the surface of the stainless steel. This prevents rust from forming.
304 stainless steel sheet
Instruction:
304 stainless steel is a versatile stainless steel material, anti-rust performance stronger than
the 200 series stainless steel. High temperature also relatively good, the general temperature
limit is less than 650 °C. 304 stainless steel with excellent corrosion resistance and good
resistance to intergranular corrosion. On the oxidizing acid, in the experiment: the concentration
of ≤ 65% of the boiling temperature of nitric acid, 304 stainless steel is highly resistant to corrosion.
Alkali solution and organic acids and inorganic acids also have good corrosion resistance.

2. 304 Stainless steel sheet Chemical Composition and Physical Properties :
Corrosion Resistance of StainlessSteel 304
Stainless steel 304 has excellent corrosion resistance in a wide variety of environments and when in contact with different corrosive media. Pitting and crevice corrosion can occur in environments containing chlorides. Stress corrosion cracking can occur at temperatures over 60°C.
Heat Resistance of Stainless Steel 304
Stainless steel 304 has good resistance to oxidation in intermittent service up to 870°C and in continuous service to 925°C. However, continuous use at 425-860°C is not recommended if corrosion resistance in water is required. In this instance 304L is recommended due to its resistance to carbide precipitation.
Where high strength is required at temperatures above 500°C and up to 800°C, grade 304H is recommended. This material will retain aqueous corrosion resistance.
Fabrication of Stainless Steel 304
Fabrication of all stainless steels should be done only with tools dedicated to stainless steel materials. Tooling and work surfaces must be thoroughly cleaned before use. These precautions are necessary to avoid cross contamination of stainless steel by easily corroded metals that may discolour the surface of the fabricated product.
Cold Working of Stainless Steel 304
Stainless steel 304 readily work hardens. Fabrication methods involving cold working may require an intermediate annealing stage to alleviate work hardening and avoid tearing or cracking. At the completion of fabrication a full annealing operation should be employed to reduce internal stresses and optimise corrosion resistance.
Hot Working of Stainless Steel 304
Fabrication methods, like forging, that involve hot working should occur after uniform heating to 1149-1260°C. The fabricated components should then be rapidly cooled to ensure maximum corrosion resistance.
Heat Treatment of Stainless Steel 304
Stainless steel 304 cannot be hardened by heat treatment.
Solution treatment or annealing can be done by rapid cooling after heating to 1010-1120°C.
Machinability
Stainless steel 304 has good machinability. Machining can be enhanced by using the following rules:
Welding of Stainless Steel 304
Fusion welding performance for Stainless steel 304 is excellent both with and without fillers. Recommended filler rods and electrodes for stainless steel 304 is grade 308 stainless steel. For 304L the recommended filler is 308L. Heavy welded sections may require post-weld annealing. This step is not required for 304L. Grade 321 may be used if post-weld heat treatment is not possible.
