Analysis of Common Problems for Stainless Steel

Knowledge /

Analysis of Common Problems for Stainless Steel CATALOG Definition of Stainless Steel Stainless steel, also known as stainless acid-resistant steel, water-copper iron, and in Taiwanese, white iron, is a high-chromium alloy steel that remains passive, corrosion-resistant, and rust-proof in the atmosphere and in corrosive media such as acids, alkalis, and salts. It typically contains other elements such as nickel, molybdenum, vanadium, manganese, and tungsten. Chromium is the most important metallic element in determining stainless steel’s rust resistance. It achieves its “rustproof” properties by forming a dense passive film of chromium oxide (Cr₂O₃) on its surface, which isolates it from corrosive media. This passive film is self-repairing if damaged, but chloride

Galvanized Steel Guide: Analysis of key issue

Knowledge /

Galvanized Steel Guide: Analysis of key issue CATALOG Definition of Galvanized Steel Galvanized steel is a steel product coated with zinc to prevent corrosion. This treatment combines the strength of steel with the corrosion resistance of zinc, making it one of the most widely used materials in industry today. The Core Value of Galvanizing The core value of galvanizing lies in its sacrificial anodic protection mechanism: when the zinc coating is scratched or damaged, the zinc corrodes before the steel, protecting the underlying metal from damage. The zinc coating on the steel surface acts as both a physical barrier and an electrochemical barrier. On the one hand, it isolates the

About PPGI Sheet coil Common questions we need to know

Knowledge /

Common questions we need to know about PPGI Steel CATALOG PPGI Material PPGI stands for pre-painted galvanized iron, a type of color-coated steel that is often used in construction, transportation, and appliances. It is made by hot-dipping zinc-coated steel and then pre-painting it in a factory. This is different from other types of painted steel, which are painted after the zinc coating is applied. What are the colors of PPGI sheet coil ? Our company’s ppgi coils are custom-made and can be made in the color of your choice. We also offer a full range of RAL color tables for customers to choose from. Commonly used colors include RAL 3000,
