ASTM A380 is a standard that provides practices for cleaning, descaling, and passivation of stainless steel parts, equipment, and systems to remove contaminants and enhance corrosion resistance.

The 2B finish is a smooth, dull gray surface produced by cold rolling, annealing, pickling, and a final light pass on polished rolls. It provides a clean, uniform appearance with good corrosion resistance, and is ideal for applications where appearance is not critical but cleanliness and consistency are important.

EN 1.4006 stainless steel is a martensitic grade equivalent to AISI 410, known for its high strength, good hardness, and moderate corrosion resistance.

EN 1.4301 is the European equivalent of AISI 304 stainless steel—they share the same chemical composition and similar properties.

304 stainless steel contains 18% chromium and 8% nickel. It has strong resistance to rust and oxidation, can withstand harsh outdoor environments, and is very suitable for long-term use under conditions of high humidity, frequent rainfall, and large temperature differences.
