Basic Knowledge of Stainless Steel Sheet

Overview of Stainless Steel Sheet

According to different manufacturing methods, the stainless steel sheet can be divided into hot-rolled stainless steel sheet and cold-rolled stainless steel sheet, the thin cold sheet thickness is usually 0.02 to 4 mm and 4.5-50 mm. Organizational characteristics of the steels are divided into five categories: austenitic, austenitic-ferritic, ferritic, martensitic and precipitation hardening types. It must have the performance to withstand oxalic acid, sulfuric acid - ferric sulfate, nitrate, nitric acid - hydrofluoric acid, sulfuric acid - copper sulfate, phosphoric acid, formic acid, acetic acid and other acid corrosions, and now it is widely used in the chemical, food, pharmaceutical, paper, petroleum, nuclear industrial, and construction, kitchen utensils, cutlery, vehicles, household appliances various parts. In order to ensure that the various types of stainless steel plate yield strength, tensile strength, elongation and hardness can meet the mechanical property requirements, before delivery, all the patterned stainless steel sheet must have the heat treatment, annealing and aging treatment.

Corrosion Resistance of Stainless Steel Sheet

The corrosion resistance of stainless steel mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, manganese, etc.) and the internal organizational structure, and the chromium plays a major role. Stainless steel sheet with the unstable nickel-chromium alloy 304 similar resist general corrosion may affect the prolonged heating in the temperature range in the degree of chromium carbide alloys 321 and 347 in the harsh corrosive medium. It is mainly used in high temperature application, and high-temperature applications require materials with strong allergy resistance to prevent the lower temperature corrosion.

Tips to Choose Stainless Steel Sheets

When selecting the stainless steel plate, you should consider the use of operating conditions. For example, manual operation or automatic operation, the pressing machine's performance and the type, the quality of the pressing material requirements such as hardness, gloss, etc. And you have to consider the economic accounting. Every time, the new polished stainless steel sheet requirements can produce a slow-quality decorative plate number. In addition, choose the thickness of the steel plate, you should consider the use time, mass, stiffness, taking into account the strength requirements when the plate under pressure; thermal conductivity pressure distribution, pressure plate format specifications. Plate thickness, easy to bend, is bound to affect the production of decorative panels. If the thickness is too large, too heavy steel sheet not only increase the cost of the steel plate, but also will be brought on to the operator does not have to play the difficult. And you have to consider the amount should be left when process or use the stainless steel sheets.
