Product introduction

304 stainless steel plate/plate:

chemical composition:

304 stainless steel grade: 0Cr18Ni9 (0Cr19Ni9) 06Cr19Ni9 S30408

Chemical composition: C: ≤0.08, Si: ≤1.0, Mn: ≤2.0, Cr: 18.0～20.0, Ni: 8.0～10.5, S: ≤0.03, P: ≤0.035, N≤0.1.

Compared with 304L

304L has better corrosion resistance and lower carbon content.

304 has a wide range of uses and has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; good thermal processing properties, such as stamping and bending, without heat treatment and hardening phenomena (non-magnetic, use temperature -196°C~ 800°C).

304L has excellent resistance to grain boundary corrosion after welding or stress relief; it can also maintain good corrosion resistance without heat treatment, and the service temperature is

basic situation:

According to the manufacturing method, stainless steel plates are divided into two types: hot-rolled and cold-rolled. According to the structural characteristics of the steel, they are divided into five types: austenite, austenite-ferrite, ferrite, martensite and precipitation hardening. kind. It needs to withstand the corrosion of various acids, such as oxalic acid, sulfuric acid-ferrous sulfate, nitric acid, nitric acid-hydrofluoric acid, sulfuric acid-copper sulfate, phosphoric acid, formic acid, acetic acid, etc. It is widely used in chemical, food, pharmaceutical, papermaking, petroleum, atomic energy and other industries, as well as various parts and components such as construction, kitchen utensils, tableware, vehicles, and home appliances.

Stainless steel plates have smooth surfaces, high plasticity, toughness and mechanical strength, and can resist corrosion from acids, alkaline gases, solutions and other media. It is an alloy steel that is not prone to rust, but it is not absolutely rust-free.

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

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 processes such as annealing, solution treatment, and aging treatment before delivery.

The corrosion resistance of stainless steel mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and internal structure, among which chromium plays a major role. Chromium has high chemical stability and can form a passivation film on the surface of steel to isolate the metal from contact with the outside world, protect the steel plate from oxidation, and increase the corrosion resistance of the steel plate. After the passivation film is destroyed, the corrosion resistance will be reduced.

Overall features:

304 stainless steel plate has a beautiful surface and many possibilities.
