    304 VS. 316 Stainless - A-J Manufacturing stainless steel

    The generally recommended maximum chloride level for 304 stainless steel is only 200 ppm (1000 ppm for 316 stainless steel). The low free chlorine levels of typical potable water systems will not affect austenitic stainless steels. However, free chlorine concentrations of as little as 25 ppm can have a detrimental effect on them. 304/304L Stainless Steel AK Steel304/304L STAINLESS STEEL Product Description Type 304 is a variation of the base AK Steel 18-8, with a higher chromium and lower carbon content. The lower carbon content minimizes chromium carbide precipitation due to welding and its susceptibility to intergranular corrosion. In some instances Type 304 can be used in the "as-welded" condition.

In some instances Type 304 can be used in the "as-welded" condition. 304L Stainless Steel Technical Data SheetThe Type 302, 304, 304L and 305 alloys are the most susceptible of the austenitic stainless steels to stress corrosion cracking in halides because of their relatively low nickel content. Conditions which cause stress corrosion cracking are:(1) presence of halide ions (generally chloride), (2) residual tensile stresses, and (3) temperatures in Allowable stresses of typical ASME materials - Stainless SteelDivide tabulated values by 0.85 for maximum allowable longitudinal tensile stress. H1:For temperatures above 550°C, these stress values may be used only if the material is heat treated by heating to the minimum temperature specified in the material specification, but not lower than 1040°C, and quenching in water or rapidly cooling by other

The level of chlorides required to produce cracking is relatively low. Failures have been reported in environments with as little as 10 ppm chlorides.

    Cryogenic Temperatures We discussed the maximum service temperatures of common austenitic steels in Engineering Bulletin #106 and well now look at how mechanical properties of austenitic steels are influenced by very low (cryogenic) temperatures and what types of stainless steel alloys are best suited for low temperature applications. Encl. 5-EPRI Presentation - Fatigue Limit of Stainless Load Control Bending fatigue tests at temperatures up to 800°C for Type 304, 316, 321 and 347 stainless steel. Room temperature fatigue strength is approximately 22 kg/mm2 or 31.2 ksi. There is some reduction in the fatigue strength at higher temperatures. The general thumb rule is that the fatigue strength is 0.4-0.5 times the Metals and materials for low temperatures and cryogenic Among steels, only high-alloy austenitic stainless steels are suitable for these temperatures, such as 304 and 310. If welds are required, the use of low carbon variants is recommended. These alloys generally contain between 18% and 21% chromium and between 9% and 14% nickel.

    and corrosion-resistant properties at sub-zero temperatures. 316L is a low- carbon modification of 316. The control of the carbon to a maximum of 0.03% minimizes the problem of carbide precipitation during welding and permits the use of the steel in the as-welded condition in Publication No 4368 - Nickel Institutesuitable for low-temperature service. (The austenitic stainless steel types 308 and 308L are used as fillers for welding Types 304 and 304L, respectively, while Type 347 is used as filler material for Type 321 steel.) Coated electrodes appropriate for manual arc welding the various grades of stainless steel are of the types given in Table 23. Stainless Steel - High Temperature ResistanceJan 08, 2002 · This expansion coefficient not only varies between steel grades, it also increases slightly with temperature. Grade 304 has a coefficient of 17.2 x 10-6 /°C over the temperature range 0 to 100°C but increases above this temperature. The effect of thermal expansion is most noticeable where components are restrained, as the expansion results in buckling and bending.

    For example, stainless steel alloy 310 has an oxidation limit of 2000°F. It does not have sufficient creep strength to be used much above 1800°F. In a load bearing situation, the practical limit Type 304 and 304L Stainless Steel ExplainedJan 11, 2020 · Type 304L Stainless Steel Type 304L stainless steel is an extra-low carbon version of the 304 steel alloy. The lower carbon content in 304L minimizes deleterious or harmful carbide precipitation as a result of welding. 304L can, therefore, be used "as welded" in severe corrosion environments, and it eliminates the need for annealing. Type 316/316L Stainless Steels Explained - ThoughtCoMar 02, 2020 · 316 stainless steel has more carbon in it than 316L. This is easy to remember, as the L stands for "low." But even though it has less carbon, 316L is very similar to 316 in almost every way. Cost is very similar, and both are durable, corrosion-resistant, and

    What is Stainless Steel 304, 304L, 304H? - Intamet

    The main constituents of 304 stainless steel - other than iron - are Chromium and Nickel. 304 contains 18 - 20% Chromium (Cr). Chromium is the essential chemical in all stainless steel and it is that which forms the thin passive layer that makes the metal "stainless" 304 also contains 8-10.5% Nickel (Ni). What is the Temperature Range for 304 Stainless Steel vs The temperature tolerance of grade 316 stainless steel is close to that of grade 304, being just a little bit lower. As stated in an AK Steel data sheet for grade 316 stainless steel, the melting range of 316 SS is 2,500 ° F 2,550 ° F (1,371 ° C 1,399 ° C), roughly 50 to 100 degrees Fahrenheit lower than the melting point of grade
