1. Stainless Steel 304h Sheets Annd Plates Heat Resistance:

• Good oxidation resistance in intermittent service to 870O C and in continuous service to 920O C
• Continuous use of Alloy 304 in the 425-860°C range is not recommended if subsequent aqueous corrosion resistance is important
• Alloy 304H has higher strength at elevated temperatures so is often used for structural and pressure-containing applications at temperatures above about 500°C and up to about 800°C
• Alloy 304H will become sensitized in the temperature range of 425-860°C; this is not a problem for high temperature applications, but will result in reduced aqueous corrosion resistance.

2. Stainless Steel 304h Sheets Annd Plates Corrosion Resistance:

Typical applications for Types 201 are cookware, hose clamps, piston rings, transit car structural member, transit car roofing/siding, thermal window spacers, air bag containers, and truck trailer posts and door frames.

3. Stainless Steel 201 Sheets And Plates Processing:

• Resistance to corrosion in oxidizing environments is a result from the 18 to 19% chromium that the 304 alloys contain
• Resistance to moderately aggressive organic acids is a result from the 9 to 11% nickel that the 304 alloys contain
• At times, Alloy 304L may show a lower corrosion rate than the higher carbon Alloy 304; otherwise, the 304, 304L, and 304H alloys may be considered to perform uniformly in most corrosive environments.

4. Stainless Steel 304h Sheets Annd Plates Welding Characteristics:

• Readily welded by most standard processes.
• May be necessary to anneal the plate after welding
• Annealing helps restore corrosion resistance lost by the sensitization.

5. Stainless Steel 304h Sheets Annd Plates Machinability:

• Subject to work hardening during deformation
• Subject to chip breaking
• Best results achieved through slower speed, heavier feeds, good lubrication, and sharp tooling
