ASTM A240 304L stainless steel plate flanges Manufacturer

Refer to chemical composition 316 chrome steel contains factor Mo, which is the reason that 316/316L has better corrosion resistance than 304/304L, particularly in excessive temperature circumstances. Therefore, engineers often select 316 material in high temperature environments. However, if the setting consist sulfuric acid, don’t use 316/316L for top temperature, because the Molybdenum will be simply reacts to high-priced sulfur ions and kind sulfides. Alloy 304 is the usual alloy since AOD technology has made lower carbon levels more easily attainable and economical. Alloy 304L is used for welded products which may be uncovered to conditions which could trigger intergranular corrosion in service. Alloy 304H is a modification of Alloy 304 in which the carbon content is managed to a variety of 0.04-0.10 to provide improved high temperature power to parts exposed to temperatures above 800°F.

The carbon content material of Alloy 304 could permit sensitization to happen from thermal circumstances skilled by autogenous welds and heat-affected zones of welds. For this reason, the low carbon Alloy 304L is most well-liked for purposes during which the fabric is put into service in the as-welded situation. Low carbon content material extends the time necessary to precipitate a dangerous level of chromium carbides however doesn’t remove the precipitation reaction for material held for long instances in the precipitation temperature vary. It is an austenitic, corrosion resistant metal with glorious energy, toughness, fabrication characteristics and weldability. The low carbon version, 304L, may be required for full corrosion resistance when thicker sections are welded.

Only sheltered areas want occasional washing with a stream of pressurized water. In heavy industrial areas, frequent washing is advisable to remove filth deposits which could eventually trigger corrosion and impair the floor appearance of the stainless steel. Alloys 304, 304L, and 304H are also immune to moderately aggressive natural acids similar to acetic and reducing acids such as phosphoric. The 9 to eleven p.c of nickel contained by these 18-eight alloys assists in providing resistance to moderately reducing environments.

• 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.

Cooling from the anneal temperature must be at sufficiently excessive charges through °F (816°C – 427°C) to keep away from reprecipitation of chromium carbides. Alloy 309 (23% Cr 13.5% Ni) or nickel-base filler metals are used in joining the 18-eight austenitic alloys to carbon steel. The austenitic stainless steels are considered to be the most weldable of the high-alloy steels and can be welded by all fusion and resistance welding processes. The Alloys 304 and 304L are typical of the austenitic stainless steels. The fatigue energy or endurance restrict is the maximum stress beneath which material is unlikely to fail in 10 million cycles in air setting. The fatigue strength for austenitic stainless steels, as a bunch, is often about 35 % of the tensile strength. Substantial variability in service results is skilled since additional variables influence fatigue strength.
