1. Superior Corrosion Resistance
- Molybdenum Boost: 2–3% Mo content creates a shield against chlorides (seawater, deicing salts) and sulfuric acid (up to 5% concentration).
- Crevice Corrosion Resistance: 316L’s low-carbon design (≤0.03% C) prevents corrosion in stagnant environments (e.g., offshore pipeline joints).
- Pitting Resistance Equivalent (PRE): 316L achieves PRE >24, outperforming 304L (PRE <19) in marine tests.
2. High-Temperature Performance
- Service Temperature: Withstands up to 925°C (316) and 870°C (316L) without scaling.
- Thermal Stability: Critical for furnace components, jet engine parts, and nuclear reactors.
3. Hygiene & Biocompatibility
- Non-Reactive Surfaces: FDA-approved for food/beverage contact (brewery tanks, dairy equipment).
- Medical-Grade Compliance: 316LVM (vacuum melted) for surgical implants and orthopedic devices.
Industry Applications of 316L Stainless Steel Bar
316L stainless steel bars are widely recognized for their exceptional corrosion resistance, durability, and versatility, making them ideal for use in highly demanding industrial environments. As a low-carbon variant of 316 stainless steel, 316L offers superior weldability and minimizes the risk of carbide precipitation, making it the material of choice in many sectors requiring strong, long-lasting performance under harsh conditions. Welcome to inquire and ask for the lastest price.
