Stainless steel plate is generally stainless steel plate and acid resistant steel plate, is a kind of alloy steel is not easy to rust. Thickness 0.4mm-80mm width 1.m-2.5m etc. The surface formed can be used in different scenes, with corrosion resistance, high temperature oxygen resistance and physical properties. Can be used for pulp and paper equipment heat exchanger, machinery equipment, dyeing equipment, film development equipment, pipelines, coastal area building materials.


What is a stainless steel plate

Stainless steel plate is generally stainless steel plate and acid - resistant steel plate. It is an alloy steel that is resistant to rust, but not absolutely resistant to rust. Uses: pulp and paper equipment heat exchanger, mechanical equipment, dyeing equipment, film development equipment, pipelines, building materials in coastal areas, etc.


The performance of stainless steel plate

  • Corrosion resistance is the main role of chromium, stainless steel plate with unstable nickel-chromium 304 similar to the ability to resist general corrosion. Prolonged heating in the temperature range of chromium carbide levels may affect alloys 321 and 347 in badly corrosive media. It is mainly used in high-temperature applications, which require strong resistance to sensitization to prevent intergranular corrosion at lower temperatures.

  • High temperature oxidation resistance, stainless steel plate has high temperature oxidation resistance, but the oxidation rate will be affected by the exposure environment and product form and other inherent factors.

  • Physical properties, the total heat transfer coefficient of metal depends on other factors besides the thermal conductivity of the metal. In most cases, the film heat dissipation coefficient, rust and metal surface condition. Stainless steel keeps surfaces clean, so it can transfer heat better than other metals with higher thermal conductivity.


The choice of stainless steel plate

Choose stainless steel plate to consider the use of operating conditions, such as manual operation or automatic operation, the performance and type of hot press, the quality requirements of pressing material such as hardness, luster, etc.. Also consider the economic accounting, each new polishing steel plate, the number of decorative plate can produce a slow quality. In addition, the choice of the most reasonable thickness of steel plate, should consider its use time, quality, stiffness, while considering the strength requirements of plate compression; Thermal conductivity; The distribution of pressure, the size of the platen. If the steel plate thickness is not enough, easy to bend, will affect the production of decorative plate. If the thickness is too large, the steel plate is too heavy, not only increase the cost of the steel plate, but also bring unnecessary difficulties to the operation. At the same time also consider the stainless steel plate processing or use should stay the margin. The thickness of copper plate is not absolutely consistent, but strive to be consistent in the thickness of the same plate as far as possible, general medium specification saw plate, thickness tolerance is 0.05-o.15 mm. If the requirements are too strict, grinding costs will increase accordingly. Generally is the resistance to tension, hardness of large structure steel plate, mechanical damage resistance performance is greater, the use of longer durability, but the polishing cost is relatively high.


Surface characteristics of stainless steel plate







Hot rolled to specified thickness

It does not need to have a shiny surface



After cold rolling, heat treatment and pickling are carried out

General wood, deep drawing wood


Luster is stronger than NO.2D

NO.2D,After treatment, a final light cold rolling is carried out on a polishing roll

The general material


as bright as a sixpence

Non standard, but usually bright annealed surface finish with high surface reflectivity

Building materials, kitchen utensils


rough lapping

Grind with a whetstone belt of 100~200#(unit)

Building materials, kitchen utensils


Intermediate grinding

A polished surface obtained by grinding with a 150~180# abrasive belt

Building materials, kitchen utensils


Fine grind

Grind with a 240# strop abrasive belt



Very fine grinding

Grind with a 320# strop abrasive belt

Hairline grinding

It has a large number of whetstone grains when it is used for grain grinding (150~240#)

Buildings, building materials


Close to mirror grinding

Grind with 600# rotary polishing wheel

For art or decoration


mirror ultrafinish

The mirror is ground with a polishing wheel

Reflector, decorative
