1. Stainless Steel 304l Sheets And Plates Corrosion Resistance:

• Resistance to corrosion in oxidizing environments is a result of the 18 to 19% chromium that the 304 alloys contain.
• Resistance to moderately aggressive organic acids is a result of 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 may be considered to perform uniformly in most corrosive environments.
• Alloy 304L is preferred for use in environments sufficiently corrosive to cause intergranular corrosion of welds and heat-affected zones on susceptible alloys.

2. Stainless Steel 304l Sheets And Plates Heat Resistance:

• Good oxidation resistance in intermittent service to 1600°F and in continuous service to 1690°F.
• CContinuous use of 304 in the 800-1580°F range is not recommended if subsequent aqueous corrosion resistance is important.
• Grade 304L is more resistant to carbide precipitation and can be heated into the above temperature range.

3. Stainless Steel 304l Sheets And Plates Welding Characteristics:

Excellent welding properties; post-weld annealing is not required when welding thin sections. Two important considerations in producing weld joints in the austenitic stainless steels are:

• preservation of corrosion resistance
• avoidance of cracking

4. Stainless Steel 304l Sheets And Plates Machinability:

• The use of chip breakers is advised since the chips can be stringy. Stainless steel work harden rapidly, heavy positive feeds, sharp tooling, and a rigid set-up should be used.of cut below the work-hardened layer resulting from the previous passes.
