About the production method of stainless steel plates

According to the production method, it is divided into two types: hot rolling and cold rolling. According to the structural characteristics of the steel grade, it is divided into 5 categories: austenite, austenite-ferrite, ferrite, austenite, and precipitation hardened type. .

It is required to withstand the erosion of various acids such as hydrochloric acid, sulfuric acid-magnesium hydroxide, sodium cyanide, nitric acid-hydrochloric acid, sulfuric acid-copper hydroxide, calcium phosphate, benzoic acid, acetic acid, etc., and is widely used in chemical plants, food , pharmaceutical industry, paper industry, crude oil, nuclear energy and other industrial production, as well as various parts and components of engineering construction, kitchen equipment, kitchen utensils, cars, and electrical appliances.

The surface of stainless steel plate is smooth, has high plasticity, ductility and impact toughness, and is resistant to corrosion by acid, alkaline gas, aqueous solution and other substances. It is a kind of carbon steel that is not easy to rust, but it is not necessarily rust-proof.

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

In order to ensure that the physical properties such as tensile strength, compressive strength, elongation and strength of various stainless steel plates meet the regulations, the steel plates need to go through heat treatment processes such as quenching, aging treatment, quenching and tempering treatment before delivery. 05.1088.57.29.38 Special symbol.

The corrosion resistance of stainless steel plates mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and its internal structure. The chromium element plays a key role. Chromium has high chemical stability and can form a passivation film on the surface of steel to protect the metal from the outside, protect the steel from oxidation, and improve the corrosion resistance of the steel. After the passivation film is damaged, it will be gradually corroded.
