Sandmeyer Steel Company is your one-stop store for stainless-steel and nickel alloy plates for the commercial nuclear power trade. Whether it’s for brand new building or restore and maintenance, we’re your answer for all of your from-inventory delivery requirements. A temperature gradient is produced within the material being welded which ranges from above the melting temperature within the molten pool to ambient temperature at a long way from the weld. The higher the carbon level of the fabric being welded, the higher the chance that the welding thermal cycle will end result within the chromium carbide precipitation which is detrimental to corrosion resistance. To provide at the most effective stage of corrosion resistance, low carbon material must be used for materials put in service in the welded condition. Alternately, full annealing dissolves the chromium carbide and restores a high degree of corrosion resistance to the standard carbon content materials.

Type 304L also has a slightly decrease yield and tensile power than Type 304. The term ‘corrosion resistant steel’ is used when the alloy has lower than the 12% minimal of chromium, for example in the aviation trade. There are completely different grades and surface finishes of stainless steel, relying on the place it is going to be used. Stainless steels have the next resistance to oxidation and corrosion in lots of pure and man-made environments; nevertheless, you will need to select the type of stainless-steel for the use.

How can I tell if my stainless steel is 304 or 316?

You can’t tell just by looking at it. There’s no visible difference between two identical pieces of sheet metal, a polished or grained the exact same way. That’s why you need a material test report (MTR) of the actual material to validate it as being 304 or 316.

304/304L/304H Stainless Steel Strips, Sheet & Plate are a chunk of the austenitic group of stainless-steel and they’re a standout amongst essentially the most versatile and usually utilized assortments of stainless plate. They are a reasonably minimal effort stainless merchandise and utilized as a part of an assortment of utilizations. 304 evaluations have amazing low temperature properties and react properly to solidifying by chilly . 304 evaluations have nice welding attributes and post weld tempering just isn’t usually required to reestablish execution. There are a number of good properties that the product is having that have made it an ideal selection. It is like good dimensional accuracy, excessive tensile energy, rugged construction, glorious surface finishes, withstanding heavy masses/high temperature/excessive strain.

    • 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.
