Cold Rolled Customized Color 6mm Thickness 304 304l Stainless Steel Sheet

304 stainless steel: 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: ≤ 0.035N ≤0.1.

With 304L
304L is more corrosion resistant, 304L contains less carbon.

304 is widely used, with good corrosion resistance, heat resistance, low temperature strength and mechanical properties; Stamping bending and other good thermal processing, no heat treatment hardening phenomenon (no magnetic, using temperature -196°C~800°C).

304L has excellent resistance to grain boundary corrosion after welding or stress elimination. In the case of no heat treatment, can also maintain good corrosion resistance, using temperature of -196°C-800°C.

According to the microstructure characteristics of steel grades, it can be divided into 5 types: austenite type, austenite-ferrite type, ferrite type, Martensite type and precipitate hardening type. Requirements can withstand oxalic acid, sulfuric acid-ferric sulfate, nitric acid, nitric acid-hydrofluoric acid, sulfuric acid-copper sulfate, phosphoric acid, formic acid, acetic acid and other acids corrosion, widely used in chemical industry, food, medicine, paper making, petroleum, atomic energy and other industries, as well as construction, kitchenware, tableware, vehicles, household appliances and various parts.

Stainless steel plate surface smooth, high plasticity, toughness and mechanical strength, acid, alkaline gas, solution and other media corrosion. It is an alloy steel that is resistant to rust, but not absolutely resistant to rust.

Stainless steel plate according to the method of hot rolling and cold rolling of two, including thickness of 0.02-4 mm thin cold plate and 4.5-100 mm thick plate.

In order to ensure that all kinds of stainless steel plate yield strength, tensile strength, elongation and hardness and other mechanical properties meet the requirements, steel plate before delivery must undergo annealing, solution treatment, aging treatment and other heat treatment

The corrosion resistance of stainless steel mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and internal organizational structure, the main role is chromium element. Chromium has high chemical stability, forming a passivation film on the surface of the steel, isolating the metal from the outside world, protecting the steel from oxidation and increasing the corrosion resistance of the steel. The corrosion resistance of the passivation film decreases when it is damaged.
