ASTM A312 TP304L Seamless Steel Square Fin Tube For Boiler Heat Exchanger
ASTM A312 TP304L Seamless Steel Square Fin Tube For Boiler ,Heat exchanger
TP304L stainless steel is primarily composed of 18%-20% chromium and 8%-10.5% nickel. This alloy composition gives it outstanding corrosion resistance in oxidative environments, such as air, water, and many common chemical substances.It can resist the corrosion of most oxidative acids and is not easily corroded by common acidic foods, making it very suitable for use in food processing equipment.P304 stainless steel has high tensile strength and yield strength, while also possessing good toughness, which allows it to maintain structural stability and integrity under various complex working conditions.
