304L stainless steel polished round bar is a material, using special process smelting, with high hardness and high toughness, can withstand corrosion from a variety of acidic substance, widely used in various industries. Stainless steel plate depending on the proportion of ingredients, some of the advantages of the properties have also slightly different. This article will introduce some knowledge of the 304L stainless steel polished round bar for you.
Excellent in a wide range of atmospheric environments and many corrosive media. Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above about 50°C. Considered resistant to potable water with up to about 200mg/L chlorides at ambient temperatures, reducing to about 150mg/L at 60°C. Consult Atlas Technical Assistance for specific environmental recommendations.
Good oxidation resistance in intermittent service to 870°C and in continuous service to 925°C. Continuous use of 304 in the 425-860°C range is not recommended if subsequent aqueous corrosion resistance is important, but 304L and dual certified product 304/304L does not suffer from this problem. For temperatures above 500°C specific high-temperature grades would normally be chosen such as 304H, 321H, 310 or S30815.

304L stainless steel polished round bar standard size effect:
Stainless steel will not produce corrosion, pitting, corrosion or wear. One of the highest strength of the material with a metal material or stainless steel construction. Because stainless steel has good corrosion resistance, so it can maintain a permanent structural component engineering design integrity. Chromium stainless steel is also set mechanical strength and high elongation in one, easy-to-parts manufacturing, to meet the needs of architects and structural designers.
