304What is the specific gravity of stainless steel

It is generally believed that the density of iron plate is 7850 kg/cubic meter, and the density of 304 stainless steel plate is 7930 kg/cubic meter

Volume: 1.5 * 6 * 0.005=0.045 cubic meters, therefore, the mass of the iron plate: M=pV=7850 kg/cubic meter * 0.045 cubic meter=353.25 kg

304Stainless steel plate quality: M=pV=7930 kg/m3 * 0.045 m3=356.85 kg

304Characteristics of stainless steel plate:

304Stainless steel plates have good corrosion resistance, heat resistance, low-temperature strength, and mechanical properties. They have good hot working properties such as stamping and bending, and no heat treatment hardening phenomenon (non-magnetic, operating temperature -196 ℃~800 ℃). 304L stainless steel plate has a much lower carbon content than 304, and it has better resistance to pitting corrosion at welding points or other treated areas compared to 304.

304LAfter welding or stress relief, its resistance to grain boundary corrosion is strong; It can maintain good corrosion resistance even without heat treatment, with a usage temperature of -196 ℃~800 ℃.

Basic Information

According to the manufacturing method, there are two types of steel: hot-rolled and cold-rolled. According to the structural characteristics of the steel grade, it can be divided into five categories: austenitic, austenitic ferritic, ferritic, martensitic, and precipitation hardening. It is required to withstand corrosion from various acids such as oxalic acid, sulfuric acid iron sulfate, nitric acid, nitric acid copper sulfate, phosphoric acid, formic acid, acetic acid, etc. It is widely used in industries such as chemical, food, pharmaceutical, papermaking, petroleum, atomic energy, as well as various components of buildings, kitchenware, tableware, vehicles, and household appliances.

Stainless steel plates have a smooth surface, high plasticity, toughness, and mechanical strength, and are resistant to corrosion from acid, alkaline gases, solutions, and other media. It is an alloy steel that is not easily rusted, but it is not rust free.

Stainless steel plates are divided into two types according to the manufacturing method: hot-rolled and cold-rolled, including thin cold plates with a thickness of 0.02-4 millimeters and medium thick plates with a thickness of 4.5-100 millimeters.

In order to ensure that the mechanical properties such as yield strength, tensile strength, elongation, and hardness of various stainless steel plates meet the requirements, the steel plates must undergo heat treatment such as annealing, solution treatment, and aging treatment before delivery. 05.10 88.57.29.38 Special symbols

The corrosion resistance of stainless steel mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and internal structure, with chromium playing a major role. Chromium has high chemical stability and can form a passivation film on the surface of steel, isolating the metal from the outside world, protecting the steel plate from oxidation, and increasing its corrosion resistance. After the passivation film is damaged, the corrosion resistance decreases.

304The density of stainless steel is 7.93 g/cm3. Austenitic stainless steel generally uses this value, with a chromium content (%) of 17.00-19.00 and a nickel content of 304 %）8.00-10.00，

304Stainless steel is a universal stainless steel material with stronger rust resistance than 200 series stainless steel materials. It also has good high temperature resistance.

304Stainless steel has excellent corrosion resistance and good resistance to intergranular corrosion.

In the experiment, it was found that 304 stainless steel has strong corrosion resistance in nitric acid below boiling temperature with a concentration of ≤ 65%. It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids.

一般特性:

304Stainless steel plates have a beautiful surface and diverse usage possibilities. They have good corrosion resistance and high strength, making them more likely to be used as thin plates. They are resistant to high temperature oxidation and have high strength, making them resistant to fire. They can be processed at room temperature, making them easy to plastic process. As they do not require surface treatment, they are simple to maintain, clean, have high smoothness, and have good welding performance.
