Product Introduction

316 Stainless steel sheet and plate is also called marine grade stainless steel. It is a type of high-quality stainless steel widely used in industries requiring durability in harsh environments due to its excellent corrosion resistance, high strength, and durability.

This material is an alloy primarily composed of iron, chromium (16–18%), nickel (10–14%), and molybdenum (2–3%), which enhances its resistance to chloride environments and pitting corrosion.

It provides advanced corrosion and pitting resistance in more aggressive environments, making it ideal for applications involving salt water, acidic chemicals, or chloride. 316 sheet and plate also is commonly used in the food and pharmacy industry where it is required to minimize metallic contamination. It also provides superior corrosion/oxidation resistance, withstands chemical and high-saline environments, excellent weight-bearing properties, superior durability and is non-magnetic.

FAQ

Q: What makes 316 stainless steel different from 304 stainless steel?

A: The primary difference is the addition of molybdenum in 316 stainless steel, which enhances its resistance to pitting and corrosion in chloride-rich environments, making it ideal for marine and chemical applications.

Q: What are the common applications of 316 stainless steel sheet?

A: 316 stainless steel sheets are widely used in marine equipment, chemical processing, food and beverage production, medical devices, and architectural projects due to their durability and corrosion resistance.

Q: Can 316 stainless steel sheet be used in high-temperature environments?

A: Yes, 316 stainless steel can withstand high temperatures up to 870°C (1600°F) for intermittent use and 925°C (1700°F) for continuous use, making it suitable for heat exchangers and industrial applications.

Q: What surface finishes are available for 316 stainless steel sheets?

A: Common finishes include 2B (smooth, matte), No. 4 (brushed), and #8 (mirror). These finishes serve different purposes, from industrial to decorative applications.

Q: Is 316 stainless steel sheet easy to fabricate?

A: Yes, 316 stainless steel is easy to cut, bend, weld, and machine. Its excellent ductility and strength make it a versatile material for various fabrication processes.
