316 Stainless Steel Bar

Description

316 Stainless Steel Bar

Product Introduction

316 stainless steel bar is an austenitic chromium-nickel stainless steel alloy with added molybdenum (Mo)—typically 2–3%—which enhances corrosion resistance, especially against chlorides and other industrial solvents. It is one of the most corrosion-resistant grades available in commercial stainless steel products and is widely recognized for its outstanding mechanical strength, durability, and ability to withstand harsh environments.

Key Features of 316 Stainless Steel Bar

• Excellent corrosion resistance in marine and chemical environments

• High tensile and yield strength

• Non-magnetic in the annealed condition

• Good weldability and formability

• Resists scaling at high temperatures up to 870°C

Superior Corrosion Resistance

Compared to 304 stainless steel, 316 offers better resistance to pitting and crevice corrosion, making it the preferred material in:

• Marine environments

• Offshore equipment

• Chemical processing industries

• Food and pharmaceutical equipment
