safekeeping

① Pay attention to moisture, dust, oil, lubricating oil, etc. during storage to avoid surface rust, poor welding or reduced corrosion resistance.

② When water is immersed between film and steel substrate, the corrosion rate is faster than that without film.

③ The warehouse shall be kept in a clean, dry and ventilated place to maintain the original packaging state. The coated stainless steel shall avoid direct light, and the coating shall be inspected periodically. If the coating deteriorates (the service life of the coating is 6 months), it shall be replaced immediately. If the packaging material is wet when padding paper is added, the padding shall be removed immediately to prevent surface corrosion.

transport

In order to avoid surface scratch during transportation, rubber or sleepers shall be used and stainless steel shall be used to protect * * * * * * materials as far as possible. In order to avoid surface pollution caused by fingerprints, gloves shall be worn during operation. The following table shows the introduction of high temperature resistant stainless steel plate with high unit price

Heat resistant steel is often used to manufacture parts working at high temperature in boilers, steam turbines, industrial furnaces, aviation, petrochemical and other industrial departments.

309S stainless steel plate: (0cr23ni13)

Characteristics: it can withstand repeated heating below 980 ℃, and has high high temperature strength, oxidation resistance and carburization resistance.

Purpose: furnace material.

310S stainless steel plate: (0Cr25Ni20)

Features: suitable for making various furnace components, * * * temperature 1200 ℃, continuous service temperature 1150 ℃.

Application: furnace material, automobile purification device material.

253MA ：

Characteristics: 253MA of Avesta Sheffield AB is a heat-resistant austenitic stainless steelstainless steel）, designed for applications requiring high creep strength and good corrosion resistance. Its service temperature range is 850 ~ 1100 ℃.

Usage: in addition to the alloying elements chromium and nickel, this brand of stainless steel also contains a small amount of rare earth metals (REM), which obviously ****************************************************************. Nitrogen was added to ****** creep properties and make the steel completely austenitic. Although the chromium and nickel contents are relatively low, this stainless steel has the same high temperature characteristics as high alloying alloy steel and nickel base alloy in many cases.
