Type 304L is an austenitic grade of stainless steel commonly used in stainless steel casting with a minimum of 18% chromium and 8% nickel. Type 304L has a maximum carbon content of 0.030. It is the standard "18/8 Stainless Steel" commonly found in the food industry. 304L stainless steel castings are the most versatile and widely used stainless steel castings.. Ideal for a variety of domestic and commercial applications, 304L alloy offers excellent corrosion resistance and is easy to fabricate with excellent formability.
Corrosion resistance:
Alloy 304 contains 18% to 19% chromium to resist corrosion in oxidizing environments.
Alloy 304 contains 9% to 11% nickel and is resistant to moderately aggressive organic acids.
Alloy 304L may sometimes exhibit a lower corrosion rate than high carbon alloy 304; otherwise, 304, 304L and 304H can be considered to perform equally in most corrosive environments.
Alloy 304L is preferred for use in environments sufficiently corrosive to cause intergranular corrosion of welds and heat-affected zones of sensitive alloys.
Heat resistance:
Good oxidation resistance in intermittent service to 1600°F and continuous service to 1690°F.
If subsequent water corrosion resistance is important, 304 is not recommended for continuous use in the 800-1580°F range.
Grade 304L is more resistant to carbide precipitation and can be heated to the above temperature range.
JCcasting can customize a series of grades of stainless steel castings, such as 304, 304L, 316, 316L, 17-4PH, 2205 duplex stainless steel, etc.
