Product Description
Stainless Steel 304 is the most widely used stainless steel grade. AMS 5647 304L Bar is a chromium-nickel austenitic stainless steel with relatively low carbon content and somewhat higher chromium and nickel than AISI types 301 and 302. SS 304L Rod is useful where sanitation and cleanliness are important. Non magnetic in the annealed condition. Hardness and tensile strength can be increased by cold working, but modified by lowered carbon content providing good resistance to corrosion in welded construction where subsequent heat treatment is not practical. In addition, The L in the 304L Round Bars indicates that the alloy is the low carbon version of the 304 grade stainless steel. The SS 304LRound Bars scomes with improved weldable properties. It can effectively resist sensitization from grain boundary precipitation.
What is AMS 5647?
The AMS 5647 is the AMS number of the 304L grade stainless steel. The specification offers exactly the same material as 304L ss, and hence the properties like corrosion resistance and high weldability are also the same. Different types of products like bars, wires, forgings, tubing, etc., can be made with the help of this stainless steel grade.
Applications of SS 304 and SS 304L
• To manufactures tanks and tools
• Food industry appliances and equipment
• Fasteners used in corrosive marine environments
• Architectural apparatus
• Filtration screens
Characteristics of SS 304 & SS 304L
