Stainless Steel Sheets 4x10ft 16GA, ASTM A167, Heat-Resistant,
Lightweight, Auto Exhaust Systems
stainless steel sheet (4x10ft, 16 gauge / 1.6mm thickness) is a high-performance material engineered for demanding
automotive exhaust systems. Manufactured in compliance with ASTM A167, this sheet combines exceptional heat resistance (up to 870°C)
with lightweight durability, making it ideal for reducing vehicle
emissions and improving fuel efficiency. The austenitic
chromium-nickel alloy ensures superior oxidation resistance,
thermal stability, and corrosion resistance against road salts,
moisture, and acidic exhaust byproducts. Precision-rolled to a
smooth finish, it minimizes friction in exhaust flow while
maintaining structural integrity under extreme thermal cycling.
