1.4306 Round Bar Supplier

Looking for 1.4306, X2CrNi19-11 or AISI 304L round bars?

WTE PowerSteel is a European supplier and stockholder of 1.4306 (X2CrNi19-11 / AISI 304L) austenitic stainless steel for corrosion-resistant engineering applications. We supply certified round bars with full material traceability, EN 10204 3.1 certification and fast worldwide delivery.

1.4306 is a low-carbon chromium-nickel stainless steel offering excellent corrosion resistance, outstanding weldability and very good formability. Thanks to its reduced carbon content, it minimizes the risk of intergranular corrosion after welding, making it an ideal material for welded components operating in aggressive industrial environments.

The alloy is widely used for manufacturing pressure vessels, piping systems, valves, pumps, tanks and process equipment. Its excellent corrosion resistance and hygienic properties make 1.4306 a preferred material for chemical processing, food & beverage, pharmaceutical, water treatment and general industrial applications.

Why Choose 1.4306?

Compared with standard austenitic stainless steels, 1.4306 (X2CrNi19-11) provides excellent corrosion resistance together with improved weldability and resistance to intergranular corrosion.

Frequently Asked Questions

What is 1.4306 stainless steel?

1.4306 (X2CrNi19-11) is a low-carbon austenitic stainless steel equivalent to AISI 304L. It offers excellent corrosion resistance, outstanding weldability and very good formability, making it suitable for pressure vessels, piping systems and welded process equipment.

Is 1.4306 suitable for welded constructions?

Yes. Thanks to its low carbon content, 1.4306 minimizes the risk of intergranular corrosion after welding. It is widely used for tanks, piping systems, pressure vessels and other welded stainless steel equipment operating in corrosive environments.

What is the equivalent of 1.4306?

The closest international equivalents include AISI 304L, UNS S30403, TP304L, SUS304L and BS 304S11. Material selection should always be verified against the applicable specification and project requirements.

What is the difference between 1.4306 and 1.4307?

Both 1.4306 (X2CrNi19-11) and 1.4307 (X2CrNi18-9) are low-carbon austenitic stainless steels comparable to AISI 304L. The main difference is the specified nickel content. 1.4306 has a higher minimum nickel content, providing improved corrosion resistance and better toughness, particularly at low temperatures. 1.4307 has a slightly lower nickel range and is commonly used for general industrial applications. Both grades offer excellent weldability and corrosion resistance, but the final material selection should always follow the applicable standard and project requirements.
