Alloy 304L -300 series stainless steel austenitic, which has a minimum of 18% chromium and 8% nickel. Type 304L has a carbon maximum is 0.030. It is the standard “18/8 stainless” that is commonly found in pans and cooking tools. Alloys 304L is the most versatile and widely used alloy in the stainless steel family. Ideal for a wide variety of home and commercial applications, Alloys 304L exhibits excellent corrosion resistance and has a high ease of fabrication, outstanding formability. The austenitic stainless steels are also considered to be the most weldable of the high-alloy steels and can be welded by all fusion and resistance welding processes.
304 Chemical compostion
Hardness (HRB): ≤ 90
Tensile strength (Mpa): ≥ 520
yield strength (Mpa): ≥ 205
elongation %: ≥ 40
Corrosion Resistance :
* Resistance to corrosion in oxidizing environments is a result of the 18to 19% chromium that the 304 alloys contain
*resistance to moderately aggressive organic acids is a result of the 8 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 maybe considered to perform uniformly in most corrosive environment
*Alloy 304L is preferred for use in environments sufficiently corr0sive to cause intergranular corrosion of welds and heat-affected zones on susceptible alloys.
