Construction Cases

• This is a construction method in which the STS flat irons are arranged in a checkerboard pattern, with the main materials such as STS304, STS329J3L, and STS329LD welded and fixed onto the structure with set anchors. The STS forming boards are then overlaid by 5-10 m between the boards and welded onto the flat iron to be made watertight.

• STS329J3L, the main material, is a high-priced grade of steel, and the POSCO data indicates that its hardness is 1.6 times and corrosion-resistance is 30 times higher than that of STS304, which is why it is used as a main material for cleaning and distributing reservoirs with a high concentration of chlorine. For other general reservoirs, STS329LD or STS304 are used as main materials depending on the chlorine concentration.

• STS329LD was developed as a substitution for the existing STS316, and it is less expensive than STS316 while its corrosion-resistant is similar to that of STS316.
