ASTM A240 316L Low Carbon Austenitic Stainless Steel Plate For Reactors , Heat Exchanger
ASTM A240 specifies the requirements for chromium, chromium-nickel, and chromium-manganese-nickel stainless steel plate, sheet, and strip used in pressure vessels and general applications. Grade 316L is a low-carbon austenitic stainless steel renowned for its superior corrosion resistance, weldability, and versatility.
ASTM A240 316L stainless steel plate is a go-to material for applications demanding excellent corrosion resistance, weldability, and moderate high-temperature performance. Its molybdenum and low-carbon composition make it ideal for chemical, marine, medical, and architectural uses.

Application
316L plates are widely used in industries requiring corrosion resistance and durability:
- Chemical Processing: Tanks, reactors, and piping for aggressive chemicals.
- Marine and Coastal: Boat components, offshore platforms (limited chloride exposure).
- Pharmaceutical/Medical: Surgical instruments, bioreactors (non-reactive, sterilizable).
- Food and Beverage: Equipment for brewing, dairy, and processing (hygienic, FDA-compliant).
- Architecture: Coastal building cladding, structural components.
- Energy: Flue gas desulfurization (FGD) systems, heat exchangers.
