In basic, all three grades are being elongated by way of the maximum limit of 40%. Also, they have the very best melting level at 1400 degrees Celsius aside from the 304H. A temperature gradient is produced within the materials being welded which ranges from above the melting temperature in the A240 SS304L steel plate MILL molten pool to ambient temperature at some distance from the weld. The greater the carbon degree of the material being welded, the greater the chance that the welding thermal cycle will outcome within the chromium carbide precipitation which is detrimental to corrosion resistance.

Minimum mechanical properties for annealed Alloys 304 and 304L austenitic stainless steel plate as required by ASTM specs A240 and ASME specification SA-240 are shown under. Exposure of the 18-8 austenitic stainless steels to temperatures in the 800°F to 1500°F (427°C to 816°C) vary might trigger precipitation of chromium carbides in grain boundaries. Such steels are “sensitized” and topic to intergranular corrosion when exposed to aggressive environments. The carbon content material of Alloy 304 may enable sensitization to occur from thermal conditions skilled by autogenous welds and warmth-affected zones of welds.

What does l mean in stainless steel?

The L indicates low carbon grades. The “L” grade material helps reduce the possibility of carbide precipitation forming during processes such as welding.

    • 304 is a kind of universal stainless steel, which is widely used to make equipment and parts with good comprehensive performance (corrosion resistance and formability).
    • 301 stainless steel presents obvious work hardening phenomenon during deformation, which is used in various occasions requiring higher strength.
    • 302 stainless steel is essentially a variety of 304 stainless steel with higher carbon content, which can obtain higher strength by cold rolling.
    • 302B is a kind of stainless steel with high silicon content, which has high oxidation resistance at high temperature.
    • 303se and 303se are free cutting stainless steels containing sulfur and selenium respectively, which are mainly used in the occasions requiring easy cutting and high surface finish. 303se stainless steel is also used to make machine parts requiring hot upsetting because it has good hot workability under such conditions.
    • 304L is a variant of 304 stainless steel with low carbon content, which is used for welding. The lower carbon content makes the carbides precipitated in the heat affected zone near the weld to a minimum, and the precipitation of carbides may cause intergranular corrosion (welding corrosion) of stainless steel in some environments.
    • 304n is a kind of stainless-steel containing nitrogen. The purpose of adding nitrogen is to improve the strength of steel.
    • 305 and 384 stainless steels contain high nickel, and their work hardening rate is low, so they are suitable for various occasions with high requirements for cold formability.
    • 308 stainless steel is used for welding rod.
    • The contents of Ni and Cr in 309, 310, 314 and 330 stainless steels are relatively high in order to improve the oxidation resistance and creep strength of the steels at high temperature. However, 309S and 310S are variants of 309 and 310 stainless steels, but the difference is that the carbon content is low, so as to minimize the carbide precipitated near the weld. 330 stainless steel has high carburizing resistance and thermal shock resistance
    • Type 316 and 317 stainless steels contain molybdenum, so their pitting corrosion resistance in marine and chemical industry environments is much better than that of 304 stainless steel. Among them, type 316 stainless steel includes low carbon stainless steel 316L and high strength stainless steel containing nitrogen.
    • 316N and 316F, a free cutting stainless steel with high sulfur content.
    • 321, 347 and 348 are stainless steels stabilized with titanium, niobium plus tantalum and niobium respectively. They are suitable for welding at high temperature. 348 is a kind of stainless steel which is suitable for nuclear power industry.
    • The forging property of 304L stainless steel is poor and the deformation is difficult.
