Stainless Steel Sheet

Parameter

Stainless steel plate surface smooth, high plasticity, toughness and mechanical strength, acid, alkaline gas, solution and other media corrosion resistance. It is an alloy steel that does not rust easily, but not absolutely. Stainless steel plate refers to the corrosion resistance of weak medium such as atmosphere, steam and water steel plate, and acid resistant steel plate refers to the corrosion resistance of chemical etched medium such as acid, alkali, salt steel plate.

Product introduction

Stainless steel plate is generally stainless steel plate and acid-resistant steel plate. Coming out at the beginning of this century, the development of stainless steel plate for the development of modern industry and scientific and technological progress has laid an important material and technological foundation. There are many kinds of stainless steel plate, different performance, it has gradually formed several categories in the process of development. According to the structure is divided into austenitic stainless steel plate, martensitic stainless steel plate (including precipitation hardening stainless steel plate), ferritic stainless steel plate, and austenitic ferritic biphase stainless steel plate and so on four categories? According to the main chemical composition of the steel plate or some characteristic elements in the steel plate to be classified into chromium stainless steel plate, chromium nickel stainless steel plate, chromium nickel molybdenum stainless steel plate and low carbon stainless steel plate, high molybdenum stainless steel plate, high purity stainless steel plate. According to the performance characteristics and use of steel plate classification, is divided into nitric acid resistant stainless steel plate, sulfuric acid resistant stainless steel plate, pitting stainless steel plate, stress corrosion resistant stainless steel plate, high strength stainless steel plate. According to the functional characteristics of the steel plate, it is divided into low temperature stainless steel plate, no magnetic stainless steel plate, easy cutting stainless steel plate, super plastic stainless steel plate. Currently, the commonly used classification method is according to the structural characteristics of steel plate and steel plate chemical composition characteristics and the combination of the two methods. Generally divided into martensitic stainless steel plate, ferritic stainless steel plate, austenitic stainless steel plate, duplex stainless steel plate and precipitation hardening type stainless steel plate or divided into chromium stainless steel plate and nickel stainless steel plate two categories. Typical uses: pulp and paper equipment heat exchanger, mechanical equipment, dyeing equipment, film washing equipment, pipelines, coastal area building external materials, etc.

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

Stainless steel sheet performance

Corrosion resistance

The stainless steel plate has similar resistance to general corrosion as the unstable nichcr 304. Prolonged heating in the chrome-carbide degree temperature range may affect alloys 321 and 347 in harsh corrosive media. It is mainly used in high temperature applications, where the material is required to have strong sensitization resistance to prevent intergranular corrosion at lower temperatures.

High temperature oxidation resistance

Stainless steel plates have high temperature oxidation resistance, but the oxidation rate will be affected by exposure environment and product form and other inherent factors.

Physical property

The total heat transfer coefficient of a metal depends on other factors besides the thermal conductivity of the metal. In most cases, film heat dissipation factor, rust and metal surface condition. Stainless steel keeps the surface clean, so its heat transfer is better than other metals with higher thermal conductivity. Liaocheng Suntory stainless Steel provides eight, stainless steel plate technical standards stainless steel plate corrosion resistance, bending processing performance and toughness of welding parts, as well as welding parts of the stamping processing performance of excellent high strength stainless steel plate and its manufacturing method. Specifically, the contents of C: below 0.02%, N: below 0.02%, Cr: More than 11%, less than 17%, appropriate content of Si, Mn, P, S, Al, Ni, And meet 12≤Cr Mo 1.5Si≤17, 1≤Ni 30(C N) 0.5(Mn Cu)≤4, Cr 0.5(Ni Cu) 3.3Mo≥16.0, 0.006≤C N≤0.030 stainless steel plate heating to 850 ~ 1250℃, Then the heat treatment is carried out at a cooling rate of more than 1℃/s. This can become a high strength stainless steel plate containing 12% volume fraction with martensite structure, 730MPa above high strength, corrosion resistance and bending performance, welding heat affected zone toughness excellent. Using Mo, B, etc., can significantly improve the stamping performance of welding parts.
