Product description

304 stainless steel is widely used as a kind of chromium - nickel stainless steel. As a widely used steel,its characteristic is corrosion resistance, good heat resistance, high strength in low temperature, easy to process on punching, bending and other thermal processing, non hardening heat treatment (when temperature is -196℃ to 800℃), Corrosion resistant in the atmosphere,if it is in the industrial atmosphere or heavy pollution areas, you need to clean in time to avoid corrosion.


304 Stainless Steel Sheet

Stocks 304 Stainless steel - a grade that is often purchased as a "304/304L dual certified stainless" and is a very low carbon austenitic chromium-nickel steel with good corrosion resistance and superior resistance to intergranular corrosion following welding or stress relieving. The low carbon content in 304 Stainless Steel limits the formation of harmful carbides to such an extent that this grade may be safely used for most operations of welded construction, and where the service temperature is limited to 800 degrees F 304 Stainless Steel is non-magnetic in the annealed condition and not hardenable by heat treatment.

High temperature oxidation and strength, so it can withstand fire

Normal temperature machining, which is easy to plastic processing

Because it is not necessary to surface treatment, it is simple and easy to maintain

Clean, high finish

Good welding performance


Basic Information

According to the two kinds of hot rolling and cold rolling, according to the microstructure characteristics of the steel grades, it is divided into 5 categories: austenitic body, austenite-ferritic body, ferrite body, martensite shape, precipitation hardening type. The request can withstand oxalic acid, sulfuric acid-ferric sulfate, nitric acid, nitric acid-hydrofluoric acid, sulfuric acid-copper sulfate, phosphoric acid, formic acid, acetic acids and other corrosion, widely used in chemical industry, food, medicine, papermaking, Petroleum, atomic energy and other industries, as well as construction, kitchenware, tableware, vehicles.


Stainless steel sheet surface is bright and clean, have high plasticity, toughness and mechanical strength, acid, alkaline gas, solution and other medium corrosion. It is not easy to rust the alloy steel, but not absolutely not rust.


The stainless steel sheet is divided into two kinds of hot and cold rolling, including the thickness of 0.02-4 mm thin sheet and the 4.5-100 mm medium sheet.


In order to ensure that all kinds of stainless steel sheet yield strength, tensile strength, elongation and hardness, such as mechanical properties meet the requirements, steel sheet before delivery must undergo annealing, solid solution treatment, aging treatment, such as heat treatment 05.10 88.57.29.38 Special Symbols


Corrosion resistance of stainless steel mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and the internal structure, the main role is the chromium element. Chromium has a high chemical stability, can form a passivation film on the steel surface, so that the metal is isolated from the outside world, the protection of steel sheet is not oxidized, increase the corrosion resistance of steel sheet. The corrosion resistance decreases after the passivation film is destroyed.
