Chemical Composition about stainless steel sheet
The comparison of all grades:
304 is a versatile stainless steel that is widely used to make equipment and parts that require good overall performance (corrosion resistance and formability).
301 stainless steel exhibits significant work hardening during deformation and is used in a variety of applications where higher strength is required.
302 stainless steel is essentially a variant of 304 stainless steel with a higher carbon content, which gives it a higher strength by cold rolling.
302B is a high silicon-containing stainless steel with high resistance to high temperature oxidation.
303 and 303Se are free-cutting stainless steels containing sulfur and selenium, respectively, for applications where high cutting and surface finish are required. 303Se stainless steel is also used to make parts that require enthusiasm, because under these conditions, the stainless steel has good hot workability.
304L is a variant of 304 stainless steel with a lower carbon content for applications requiring soldering. The lower carbon content minimizes the precipitation of carbides in the heat affected zone near the weld, which may result in intergranular corrosion (weld erosion) in certain environments.
304N is a nitrogen-containing stainless steel that is added to increase the strength of the steel.
305 and 384 stainless steels contain high nickel and have a low work hardening rate, making them suitable for a wide range of applications where cold formability is critical.
308 stainless steel is used to make the electrode.
The nickel and chromium contents of 309, 310, 314 and 330 stainless steel are relatively high in order to improve the oxidation resistance and creep strength of steel at high temperatures. The 309S and 310S are variants of the 309 and 310 stainless steels, except for the lower carbon content, in order to minimize the carbides precipitated near the weld. 330 stainless steel has a particularly high resistance to carburizing and thermal shock resistance.
Type 316 and 317 stainless steels contain molybdenum and are therefore much more resistant to pitting corrosion in marine and chemical industrial environments than 304 stainless steel. Among them, variants of Type 316 stainless steel include low carbon stainless steel 316L and nitrogen-containing high-strength stainless steel.
316N and free-cutting stainless steel 316F with high sulfur content.
321 , 347 and 348 are stainless steel stabilized by titanium, niobium and tantalum, respectively, and are suitable for use as welded members at high temperatures. 348 is a stainless steel suitable for the nuclear power industry with certain restrictions on the content of strontium and barium.
The forging performance of 304L stainless steel is poor and the deformation is difficult.
Due to the existence of work hardening. The amount of deformation during the lengthening of the mandrel cannot be made too large. And the heat loss is large. Therefore, it must be molded under the fire. If the high temperature insulation stage is not handled well, it will cause coarse crystals.
NO.1 silvery white, matte hot rolled to the specified thickness, and then annealed and descaled a rough, matte surface that does not need to have a surface gloss
NO.2D silver-white cold rolling is followed by heat treatment and pickling, and sometimes the final light rolling is carried out on the woolen roller.2D products with NO light surface are used for the purpose of less stringent surface requirements, and are generally used for materials and deep blanking
NO.2B luster is stronger than NO.2D NO.2D after processing, the final mild cold rolling is carried out through the polishing roller to obtain proper luster.This is the most commonly used surface finish, which can also be used as a first step in polishing.The general material
BA shine is non-standard, but it is usually treated with bright annealing, and the surface is highly reflective.Building materials, kitchenware
NO.3 rough grinding will NO.2D and NO.2B materials, grinding construction materials and kitchen utensils with 100~200# abrasive grain abrasive belt
NO.4 intermediate grinding will NO.2D and NO.2B materials, polishing surface obtained by grinding with 150~180# abrasive grain abrasive band, which is universal. The polished surface with visible 'grain' with mirror reflection is the same as above
NO.240 fine grinding will be NO.2D and NO.2B, grinding kitchen utensils with 240# grinding strip
NO.320 extremely fine grinding will NO.2D and NO.2B materials, grinding with NO.320 grinding strip
NO.400 gloss is close to BA's NO.2B material, which is grinded with 400# polishing wheel for general materials, construction materials and kitchen utensils
HL hair grain grinding suitable particle size grinding materials hair grain grinding (150~240#) many buildings, building materials
No.7 is close to mirror grinding with 600# rotary polishing wheel for fine art and decoration
NO.8 mirror lapping mirror lapping mirror with polishing wheel, for decoration
304L stainless steel, appearance, workability, strength and other properties than other materials, and many of the stainless steel surface treatment method, rich and colorful color and shape can be obtained, 304L stainless steel is a kind of universal, has good good corrosion resistance, easier assembly, excellent formability and high strength, low weight, it is widely used to make requires good comprehensive performance, corrosion resistance and formability) equipment and parts, including film, bar and plate used in equipment manufacturing food and beverage, health, frozen, pressure vessels, etc.
