316L Stainless steel plate

Product Overview

316L stainless steel plate is a premium low-carbon austenitic stainless steel grade, engineered with molybdenum (Mo) addition and strict carbon content control (≤0.03%). Compliant with ASTM A240/ASME SA240 and GB/T 20878-2024 (022Cr17Ni12Mo2) standards, it delivers exceptional corrosion resistance in chloride-rich environments, superior weldability, and stable mechanical properties across a wide temperature range (-196℃ to 800℃). As the preferred material for critical applications, it outperforms 304 stainless steel in marine, chemical, and high-humidity settings, ensuring long-term reliability and cost efficiency.

Core Advantages

1. Superior Corrosion Resistance (Chloride & Acid Resistance)

- Enhanced with 2.00%-3.00% molybdenum, forming a dense chromium-molybdenum passivation film that resists pitting, crevice corrosion, and stress corrosion cracking in chloride environments (e.g., seawater, salt spray)  .
- Critical Pitting Temperature (CPT) ≥60℃ in 3.5% NaCl solution, 2x higher than 304 stainless steel .
- Excellent resistance to sulfuric acid (concentration <15% or >85%), phosphoric acid, and organic acids, ideal for chemical processing and pharmaceutical equipment  .
- Low carbon content (≤0.03%) prevents intergranular corrosion after welding, eliminating the need for post-weld annealing  .

2. Outstanding Mechanical & Physical Properties

Property Specification 
Density 7.98 g/cm³ 
Tensile Strength ≥485 MPa 
Yield Strength ≥170 MPa 
Elongation ≥30%
