The surface of the stainless steel plate is smooth, has high plasticity, toughness and mechanical strength, and is resistant to corrosion by acids, alkaline gases, solutions and other media. It is an alloy steel that is not easily rusted. The stainless steel plate refers to a steel plate that is resistant to corrosion by weak media such as atmosphere, steam, and water, and the acid-resistant steel plate refers to a steel plate that is resistant to corrosion by chemical etching agents such as acid, alkali, and salt.stainless steel pipe supplier
The performance of stainless steel plate：
1.High temperature oxidation resistance
Stainless steel plates have high temperature oxidation resistance, but the oxidation rate is affected by inherent factors such as the exposed environment and product morphology.
The stainless steel sheet has the ability to withstand general corrosion similar to the unstable nichrome 304. Prolonged heating in the temperature range of chromium carbide may affect alloys 321 and 347 in harsh corrosive media. Mainly used in high temperature applications, high temperature applications require strong sensitization of materials to prevent intergranular corrosion at lower temperatures.
The total heat transfer coefficient of the metal depends on other factors, in addition to the thermal conductivity of the metal. In most cases, the film’s heat dissipation coefficient, scale and metal surface condition. Stainless steel keeps the surface clean and tidy, so its heat transfer is better than other metals with higher thermal conductivity. Liaocheng Suntory Stainless Steel provides technical standards for stainless steel plates. High-strength stainless steel plates with excellent corrosion resistance, bending processability and weld site toughness, and excellent stamping performance of welded parts. Specifically, it contains C: 0.02% or less, N: 0.02% or less, Cr: 11% or more and less than 17%, and an appropriate content of Si, Mn, P, S, Al, Ni, and satisfies 12 ≤ Cr Mo 1.5Si ≤ 17, 1 ≤ Ni 30 (CN) 0.5 (Mn Cu) ≤ 4, Cr 0.5 (Ni Cu) 3.3Mo ≥ 16.0, 0.006 ≤ CN ≤ 0.030 stainless steel plate is heated to 850 ~ 1250 ° C, and then carried out at 1 ° C / s The above heat treatment for cooling rate cooling. Thus, it can be a structure containing a martensite having a volume fraction of 12% or more, a high strength of 730 MPa or more, corrosion resistance, bending workability, and a high-strength stainless steel sheet excellent in weld heat-affected zone toughness. By using Mo, B, etc., the press working property of the welded portion can be remarkably improved.
The flame of oxygen plus gas cannot cut stainless steel because the stainless steel is not easily oxidized.
5CM thick stainless steel plates are machined with special cutting tools.
The selection of stainless steel plates should consider the operating conditions, such as manual operation or automatic operation, the performance and type of the hot press, and the quality requirements of the pressed materials such as hardness and gloss. Also consider the economic accounting, each time a new polished steel plate, the number of times to produce a slow quality decorative board.steel square bar
In addition, when selecting the reasonable thickness of the steel plate, the time, quality and rigidity of the steel plate should be considered, and the strength requirements of the plate under pressure should be considered; the heat conduction performance; the pressure distribution, the format of the pressure plate.
If the thickness of the steel plate is not enough, it is easy to bend, which will affect the production of decorative panels. If the thickness is too large, the steel plate is too heavy, which not only increases the cost of the steel plate, but also brings difficulty in operation. At the same time, the remaining amount of stainless steel plate processing or use should be considered. The thickness of the copper plate is not uniform, but the thickness of the same steel plate is to be as uniform as possible. Generally, the medium-sized saw blade has a thickness tolerance of 0.05-o.15 mm. If the requirements are too strict, the grinding costs will also increase. Generally, it is a steel plate with large tensile strength and hardness, and the greater the resistance to mechanical damage, the longer the durability of use, but the processing cost of the grinding boring is also relatively high.
