304L Stainless Steel Round Bar

Overview

304L stainless steel round bar is a low-carbon variation of 304 baja tahan karat, offering excellent corrosion resistance, weldability, and formability. Its low carbon content minimizes carbide precipitation during welding, making it ideal for use in high-temperature environments where welding is required.

304L is widely recognized for its versatility and cost-effectiveness, making it one of the most commonly used stainless steel grades in various industries.

Key Features of 304 Stainless Steel Bar

• Low Carbon Content (L = Low Carbon): Minimizes intergranular corrosion after welding.

• Resistensi korosi yang sangat baik: Performs well in a wide range of environments including acids, chlorides, and atmospheric conditions.

• Superior Weldability: Suitable for all standard welding techniques without the need for post-weld annealing.

• Good Formability and Machinability: Easy to cut, form, and fabricate for industrial or architectural needs.

• Non-magnetic in Annealed Condition: May become slightly magnetic after cold working.
