Common Materials Selection Guide

Material Description & Applications
65Mn Steel High carbon steel with excellent hardness and wear resistance. Commonly used for springs, tools, and automotive parts requiring high strength and durability.
316 Stainless Steel Austenitic stainless steel known for its exceptional corrosion resistance, especially in marine and chemical environments. Ideal for food processing, pharmaceuticals, and marine applications.
304 Stainless Steel The most widely used stainless steel with good corrosion resistance, formability, and weldability. Commonly used in kitchen equipment, architectural applications, and chemical industries.
Carbon Steel (Q235) Low-carbon steel with good weldability and strength. Widely used in construction, automotive, and manufacturing industries for structural components.
Surface Treatment Selection Guide
Surface Treatment Description & Applications
Dacromet A chrome-free zinc coating offering excellent corrosion resistance. Suitable for automotive and industrial equipment exposed to harsh environments.
Galvanizing (Zinc Plating) Zinc coating applied through electroplating or hot-dip, providing strong corrosion protection. Common in construction, outdoor machinery, and pipelines.
Black Oxide (Blackening) A chemical oxidation process that creates a black, protective layer on steel. Ideal for mechanical parts, automotive components, and tools where appearance and corrosion resistance are important.
Zinc-Chromate Coating A zinc coating with added chromium for enhanced corrosion resistance. Used in aerospace and high-performance applications.
Nickel Plating A nickel coating providing high hardness and excellent corrosion resistance, with a smooth surface. Used in electronics, precision parts, and industrial applications requiring high gloss and protection.
Phosphating A process that forms a phosphate layer on the metal surface, improving adhesion and corrosion resistance. Used in automotive and machinery applications requiring good paint adhesion.
