ASTM A167 16GA Stainless Steel Sheet 4x10ft Heat Resistant For Auto Exhaust Systems
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.
