926 Stainless Steel Bar Alloy 1.4529 High Precision Round Bar for Industrial Applications

Overview of UNS N08926 / 1.4529 Stainless Steel

UNS N08926, also known as 1.4529, is a high-performance alloy designed to offer excellent corrosion resistance, high strength, and good weldability. This alloy is a part of the austenitic stainless steel family, characterized by its high resistance to pitting, crevice corrosion, and stress corrosion cracking. The primary use of this stainless steel is in industries where severe environments, such as highly acidic or chloride-rich conditions, are common.

The alloy is widely used in industries like chemical processing, desalination, food production, and petrochemical processing. The high resistance to chloride-induced corrosion and its superior mechanical properties make UNS N08926 an ideal choice for applications requiring both high strength and long-lasting durability.

This product information focuses on the 926 Stainless Steel Bar Alloy 1.4529 in the form of a high-precision round bar, which is often used in critical industrial applications.

Key Properties of UNS N08926 / 1.4529 Stainless Steel Bar

Corrosion Resistance

One of the standout features of UNS N08926 (1.4529) stainless steel is its excellent corrosion resistance, particularly in environments where other alloys might fail. Its high content of molybdenum (up to 6%) and nickel (around 25%) enhances its resistance to chloride-induced stress corrosion cracking (SCC), pitting, and crevice corrosion. This makes it ideal for use in:

• Chemical processing

• Marine environments

• Power plants

• Food processing

• Water treatment and desalination plants

The alloy can withstand prolonged exposure to a wide range of aggressive chemicals such as sulfuric acid, phosphoric acid, and other oxidizing environments, which are typically harmful to lower-grade alloys.
