What Kind Of Steel Is The Stainless Steel Plate
Sep 25, 2017

Stainless steel plate is generally stainless steel plate and acid-proof steel. Stainless steel plate is the steel plate that is resistant to the corrosion of weak media such as atmosphere, steam and water, while the acid steel plate is the steel plate which is corrosive to acid, alkali, salt and other chemical etching media. The stainless steel plate has been around since the beginning of this century and has been around for more than 90 years. The invention of stainless steel plate is a great achievement in the history of world metallurgy. The development of stainless steel plate has laid an important material and technical foundation for the development of modern industry and technological progress. The steel plate of stainless steel plate is many, the performance is different, it has formed several broad categories gradually in the development process. It is divided into four categories: markov stainless steel plate (including sedimentation hardening stainless steel plate), ferritic stainless steel plate, austenitic stainless steel plate and austenitic ferrite duplex stainless steel plate. According to some characteristics of the main chemical composition of steel sheet or plate element to classification, divided into chromium stainless steel, chromium nickel stainless steel plate, nickel chromium molybdenum stainless steel plate, and low carbon stainless steel plate, high molybdenum stainless steel plate, high purity stainless steel plate, etc. According to the performance characteristics and use classification of steel plate, it is divided into the stainless steel plate, the stainless steel plate, the corrosion resistant stainless steel plate, the corrosion resistant stainless steel plate, the high strength stainless steel plate, etc. According to the functional characteristics of steel plate, it is divided into low temperature stainless steel plate, non-magnetic stainless steel plate, easy cutting stainless steel plate and ultra-plastic stainless steel plate. The current classification methods are classified according to the structure of steel plate and the chemical composition of steel plate and the combination of the two methods. It is generally divided into martensitic stainless steel plate, ferritic stainless steel plate, austenitic stainless steel plate, duplex stainless steel plate and precipitation-hardened stainless steel plate, etc. Can be divided into chromium stainless steel plate and nickel stainless steel board two kinds. Versatile? Mechanical equipment? Typical use: paper pulp and paper equipment heat exchanger, dyeing equipment, film processing equipment, pipe, coastal area building external materials, etc.
The stainless steel plate is divided into two kinds of hot rolled and cold rolled, including thin cold plate with thickness of 0.02-4mm and 4.5-100mm thick plate.
According to the organizational characteristics of the steel, there are 5 types: austenite, austenite, ferritin body type, body type, markov type, and precipitation-hardening type.
Requirements can withstand the oxalic acid, sulfuric acid, ferric sulfate, nitrate, nitric acid, hydrofluoric acid, sulfuric acid, copper sulfate, phosphoric acid, formic acid, acetic acid, etc all kinds of acid corrosion, widely used in chemical, food, medicine, papermaking, oil and atomic energy industry, and construction, kitchenware, tableware, automobile, household appliances all kinds of spare parts.
In order to ensure that all kinds of stainless steel yield strength, tensile strength, elongation and hardness and other mechanical properties conform to the requirements, prior to delivery steel after annealing, solid solution treatment and aging treatment, 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, manganese, etc.) and internal organization structure, the main function is chromium element. Chromium has high chemical stability, which can form a passivation film on the steel surface, so as to isolate the metal from the outside, protect the steel plate from oxidation, and increase the corrosion resistance of the steel plate. After the destruction of the passivation film, the corrosion resistance decreases.
According to the two kinds of hot rolling and cold rolling, the structure of the steel type is divided into five categories: austenite, austenite, ferritin, iron, markov and precipitation-hardening type. Requirements can withstand the oxalic acid, sulfuric acid, ferric sulfate, nitrate, nitric acid, hydrofluoric acid, sulfuric acid, copper sulfate, phosphoric acid, formic acid, acetic acid, etc all kinds of acid corrosion, widely used in chemical, food, medicine, papermaking, oil and atomic energy industry, and construction, kitchenware, tableware, automobile, household appliances all kinds of spare parts.
Stainless steel plate surface is clean, with high plasticity, toughness and mechanical strength, acid, alkaline gas, solution and other media corrosion. It is a kind of alloy steel that is not easy to rust, but it is not absolutely rusting.
