ASTM 304/304L stainless H beam steel

ASTM 304/304L stainless H beam steel is part of the austenitic family of stainless steel. ASTM 304/304L stainless H beam steel exhibit good machinability and have excellent weld-ability characteristics with or without the addition of filler metals. ASTM 304 H beam stainless steel is the most widely used of the austenitic (chromium/nickel) stainless steels. In the annealed condition it is essentially non-magnetic and becomes slightly magnetic with the application of cold work.

304 stainless H beam steel is preferred in welding applications to exclude the formation of chromium carbides during cooling in the heat affected region of the weld. These alloys represent an excellent combination of corrosion resistance and fabricability.

ASTM 304/304L H beam steel Chemical Composition:

Element	Type 304	Type 304L
Carbon	0.07Max	0.030 Max
Manganese	2.00Max	2.00 Max
Sulfur	0.030 Max	0.030 Max
Phosphorus	0.045 Max	0.045 Max
Silicon	0.75 Max	0.75 Max
Chromium	17.5 to 19.5	18.0 to 20.0
Nickel	8.0 to 10.5	8.0 to 12.0
Nitrogen	0.10 Max	0.10 Max

ASTM 304/304L H beam steel Mechanical Properties:

304L	485	170	40	92	201

304/304L H beam steel Welding: Types 304 and 304L are weldable by most fusion or resistance welding techniques. If filler metal is required, Type 308 is normally used. Type 304L should be used in heavier sections to reduce the occurrence of carbide precipitation in the heat affected region adjacent to the weld pool Katalor is a professional 304/304L stainless H beam steel manufacture and supplier . We offer 304/304L H beam steel . If you have any need of 304/304L stainless H beam steel , please contact us as following ways .
